hi link github.com/esimov/caire/cmd/caire is down?

Hello,
I just gave caire a try against one of my images and it seems to be spinning non-stop.

./caire -in ./source.JPG -out ./dest.JPG -width 480 -height 720

And, I then changed to perc 20 and this worked but produced the image that is almost 3 times the original size.

Not sure what I am missing. Also, -debug doesn't print anything ...

Let me know what additional info you need ...

Thanks!

It would be ideal if pipes were usable with the CLI for enabling more expanded use-cases. After having worked with ImageMagick in the past - I could see this being a highly requested feature.

With ImageMagick you can have the input arrive from a pipe, or have the output sent to a pipe.

Examples:

Pipe to file:

caire -in bridge.jpg -scale -perc 70 > small_bridge.jpg

Input from pipe:

caire -scale -perc 70 -out smaller_bridge.jpg < small_bridge.jpg

Input and output from pipe:

cat small_bridge.jpg | caire -scale -perc 70 > smaller_bridge.jpg

There are usages of pipes in the OpenFaaS CLI (also in Go) if that helps. https://github.com/openfaas/faas-cli

I'm using this library in a project of mine, and I realized that resizing was using an incredible amount of RAM, much more than I would have expected to process one image. I decided to run a memory profiler to confirm my suspicions. I tested this image, rescaling from from 2048x1536 to 1920x1080. These were the results [pdf] I got after running caire with pprof. Specifically, here was the code I used:

func resize(in io.Reader, out io.Writer) {
	defer profile.Start(profile.MemProfile).Stop()
	p := &caire.Processor {
		NewWidth:  1920,
		NewHeight: 1080,
		Scale: true,
	}

	err := p.Process(in, out)
	check(err)
}

As you can see, caire used 3.4 GB of RAM to process this one image. I decided to investigate further on what it was using this memory for, and focused on the reduce() function, which is the main function which is called repeatedly when resizing an image:

reduce := func() {
	width, height := img.Bounds().Max.X, img.Bounds().Max.Y
	c = NewCarver(width, height)
	c.ComputeSeams(img, p)
	seams := c.FindLowestEnergySeams()
	img = c.RemoveSeam(img, seams, p.Debug)
	imgs = append(imgs, img)
}

The program appends each iteration it creates to an imgs slice, which from my understanding is only used when the input is a gif, since that slice will be used to reconstruct the frames of the gif. Since I was processing a jpg, I removed the line and ran the program through a profiler again, and here were the results [pdf]. Removing this one line reduces the memory usage from 3.4 GB to only 232 MB.

I tested the change on another image and found a similar reuction, from [1.8 GB] to [231 MB]. More testing could be done, but I would propose adding another parameter to the Processor struct, like 'IsGIF', then only appending the images to the slice if this is given as true, such as

if (p.IsGIF) {
	imgs = append(imgs, img)
}

Is your feature request related to a problem? Please describe.

Because Go 1.16 offers support for embedded files, it's desirable to embed the cascade face classifier directly into the generated binary file. This way we can avoid having to provide the face classifier as a parameter for the CLI application.

In order to make it easy to use caire as a library it would be to nice to have caire using golang modules.

Hi, I'm Yevgeny Pats Founder of Fuzzit - Continuous fuzzing as a service platform.

We have a free plan for OSS and I would be happy to contribute a PR if that's interesting.
The PR will include the following

• go-fuzz fuzzers (This is generic step not-connected to fuzzit)
• Continuous Fuzzing of master branch which will generate new corpus and look for new crashes
• Regression on every PR that will run the fuzzers through all the generated corpus and fixed crashes from previous step. This will prevent new or old bugs from crippling into master.

You can see our basic example fuzzitdev/example-go and you can see an example of "in the wild" integration google/syzkaller.

Let me know if this is something worth working on.

Cheers,
Yevgeny

imageFile, err := os.Open(inPath)
if err != nil {
	return err
}
defer imageFile.Close()

outFile, err := os.Create(outPath)
if err != nil {
	return err
}
defer outFile.Close()

p := &caire.Processor{NewWidth: width, Scale: true}
return p.Process(imageFile, outFile)

I have a function along the lines of that, I've removed some superflous details.

I was trying to resize an png image of the dimension 1200 × 750 to 120 x 120. However, the terminal output stuck at Processing... - for minutes.

Can this library be used in go code. If yes, there is no link for documentation.

how do you upload an image from a source

Trying to run it on a MacbookPro (13" 2016 3.3ghz i7), but cant get anywhere past Processing message.

I've installed caire via homebrew, my sample image is the one used in the repo:

my input image is of size 204x383 (portrait).

Whenever I run

caire -in in.jpg -out out.jpg -width=$((204*3/2)) -height=$((383*3/2))

or

caire -in in.jpg -out out.jpg -width=$((383*3/2)) -height=$((204*3/2))

The output image is in landscape (though it doesn't looks the same).

Hi
since caire provide the flag '-face', but when I specified this flag, caire will report a error that is 'please provide a face classifier file'. I know Pigo is face detector which can be used here, but I don't know how to use it. Could you please help me ? Thanks in advance.

When generating an image at, for example, half "resolution", this tool creates undesirable effects as it tries to remove half the image data while keeping everything at it's current resolution, resulting in rather mangled output. The solution to this is to first resize the image using a traditional scaling method without applying any cropping, then passing the data to this tool to apply the cropping to the image.

It would be nice to see a flag, that when set, would automatically pre-scale an image before applying this algorithm to it.

eg:
Given an image of dimensions 2048x1536 if I supply a command similar to the following:
caire -in image.jpg -out thumb.jpg -width=1024 -height=500 -scale=1
it would be nice to see the tool first resize the image to 1024x768, then utilize it's existing algorithms to remove the final 268 pixels instead of its current implementation on trying to keep everything the same scale and having to remove much more data.

I don't know if keeping the original resolution image is beneficial for calculating better seems however.

after I run the resize successfully, it print out:

Rescaled in: 17.47s
Saved as: out.jpg 

where 17.47s and out.jpg are in green color, other are same as console default color.
But the reset of the console (username:folder$ ) are still in green color.

Action performed

resize an png image to a smaller image

Expected behavior

the generated image should be a png file

Actual behavior

the generated image is jpeg file

Example

beenotung:caire$ caire -in 'ctrl police esc chasing.png' -out 'ctrl police esc chasing.1.png' -perc -width 20 -height 20
Processing... |
Rescaled in: 21.94s
Saved as: ctrl police esc chasing.1.png 

beenotung:caire$ file ctrl\ police\ esc\ chasing*
ctrl police esc chasing.1.png: JPEG image data, baseline, precision 8, 690x262, frames 3
ctrl police esc chasing.png:   PNG image data, 863 x 328, 8-bit/color RGB, non-interlaced

When I try to rescale this image: https://wallhaven.cc/w/dgpj33 from its original size 3840x1080 to new size 3046x1050, this happens:

"cannot rescale to this size preserving the image aspect ratio" seems to always show up. I was under the impression that the whole purpose of this utility is to change the aspect ratio of the image?

Hey!
I feel it'd be great having this as tool as a Web App for general public to make use of. Would you be interested in building a backend over this so that a Web App (which I could build) could use it as an API.

Anyone interested in such a project feel free start a discussion cause I see potential in this!

It would be nice, if there was a method on Processor like Processor.Resize which took image.Image or something like Processor.Process which lets you control what you want to encode the image as.

For performance reasons we shouldn't encode each time the image raw pixel data into an image file when running the face detector. This way we can avoid to generate a new image at each iteration and also we can avoid of using a global TempImage variable available across the whole codebase.

Describe the bug

I installed it from the AUR (`yay -S caire).

When I'm trying this command:

caire -perc=0 -width 3840 -height 1080 -in everyone.png -out test.png

than I'm getting this:

⚡ CAIRE is resizing the image... ✔
Error resizing the image:
	Reason: scale option can not be used on image enlargement

How can I expand the image to 3840x1080?

API related bug

I don't really know what to write here... (I'm not familiar with go)

Expected behavior

That I'm getting the same image just bigger.

Screenshots

• [Screenshots, logs or errors]

Bug with the Desktop version (please complete the following information):

• Sytem information like OS: [e.g. macOS, Ubuntu]
• You are using the binary file from the uploaded releases or you are doing a manual build?

As I said in the beginning I installed it from the AUR and run it via CLI.

Additional context

Any chance you could add this to Homebrew for easier packaging and updates on macOS?

$ caire -in in.png -out out.jpg -perc=1 -width=150 -height=150 -debug=false
Processing... -
Error rescaling image: in.png. Reason: The generated image size should be less than original image size.

while specifying the enlargement size also have other problems as mentioned in #24

I used caire with a couple of images, and aside from the girl example in the README, I haven't gotten it to actually provide an output with any of the images I tried, even after 10-15mins. I have tried using different flags to make it faster, but it seems to be stuck processing forever.

Here's an example to reproduce my issue:

wget -O input.jpg "https://unsplash.com/photos/CaDoHQ3fB8w/download?force=true"
caire -in input.jpg -out output.jpg -face=false -scale -square -width=500 -height=500 -blur=0

Any suggestions?

I get this error when I use the lib as described in this tutorial: https://getstream.io/blog/go-1-11-rocket-tutorial/

# github.com/esimov/caire ../go/pkg/mod/github.com/esimov/[email protected]/process.go:18:2: imported and not used: "fmt"

Is there something related to the way the tutorial imports CAIRE ? If I delete the "fmt" import myself, then it works fine.

Trying to take the library for a spin, but it seems like the Homebrew installation is out of date. After installing and running caire --help I get the following output:

Usage of caire:
  -blur int
    	Blur radius (default 1)
  -debug
    	Use debugger
  -height int
    	New height
  -in string
    	Source
  -out string
    	Destination
  -perc
    	Reduce image by percentage
  -sobel int
    	Sobel filter threshold (default 10)
  -square
    	Reduce image to square dimensions
  -width int
    	New width

Some notable flags missing are -scale and -face. I've tried to use both of these as my images never seem to finish processing.

I tried the alternative installation method, but when I run go get -u -f github.com/esimov/caire/cmd/caire I get the following error (could open a separate issue for this if needed):

# gocv.io/x/gocv

Anyone else experiencing something similar?

Hi there, I resized an image and the yellow/green highlight got left on. I guess this may be a bug in terminator code? Is an expression missing?

Thanks,

Alex

I do not see in the docs how to enlarge an image (for example -perc1 -width 20 reduce the width in 20%)

I would love a -square option that will make the image be a square based on the shortest edge.

FYI, the image labeled "scotland" is in fact Gásadalur in the Faroe Islands, which is easily corroborated by a google image search. It's a beautiful place which I have been to many times, so I'd appreciate if the caption was fixed.

This project does look very interesting! I'd know that view from anywhere, though, so I thought I'd let you know.

I have finished go install and it have no errors. But I use caire --help to test, it show -bash: caire: command not found. Please give me some instructions. Thank you.

Describe the bug

When an image is resized both horizontally and vertically, the seam carving algorithm first will resize horizontally then vertically, but sometimes, depending on the image, this results with some unpleasant outcome. If we would process the image by applying the seam carving algorithm on horizontal and vertical axis intermittently normally the output would be much better.

In your readme you said

i'm planning to implement my own face detection library to minimize the dependency tree

I wanted to create this ticket so I could watch it and get notified when this is done. I'd love to be able to just install th binary and not have to use homebrew or install any dependencies.

Thanks

Is your feature request related to a problem? Please describe.

Because Github Actions offer more customization than Travis we can consider to migrate the CI part.

Looks like building caire using openfaas is 31 step process. I am getting the following error at Step 15.

Errors received during build:

• [caire-image-resizer] received non-zero exit code from build, error: The command '/bin/sh -c test -z "$(gofmt -l $(find . -type f -name '.go' -not -path "./vendor/" -not -path "./function/vendor/*"))" || { echo "Run "gofmt -s -w" on your Golang code"; exit 1; }' returned a non-zero code: 1

How do I go about this?

Hi, when I try to resize an image with size 2400 * 2400 with setting New_width = 180, scale = true, Square = true, face detection = true, it will not resize the image and output the original image after process, if Square option is removed, then it will resize the image correctly. I wonder if it is config problem or others?

Thank you

I'm new to Go. I have this version installed:

go version go1.9.3 darwin/amd64

I followed the basic installation instructions from the README:

$ go get github.com/esimov/caire/cmd/caire
$ go install

Afte running the go get command, I end up with a go folder in my filesystem's root. I'm not sure where I should execute go install or what should happen next. Should I simply put the caire executable in a specific folder to make it work?

Thanks for your help.
Roel

Great work on this, I'm having fun just messing around with it.

Forgive me if this is obvious - but is there a way to hide the seams on the output file? Each result I have includes the red seams on the image.

Thanks!

Hi,

thank you for this awesome library. I aspire to use it in my application for "cropping" profile images to squares when they are not uploaded as squares.

But: The library does not seem to free its used memory when it's done processing which means my server hits memory limit after two or three users uploaded their image. (200MB to 1.5GB, depending on the image)

The code I used to resize images

Please remind me if I have missed something and there is an option to cleanup.

I'm playing around with this as a library rather than a command-line utility, I wanted to do stuff in-memory without files and unfortunately Process doesn't take an io.Writer (PR incoming!) so for now, I simply copied this code:

	src, _, err := image.Decode(file)
	if err != nil {
		return nil, err
	}
	img := imgToNRGBA(src)
	res, err := Resize(p, img)
	if err != nil {
		return nil, err
	}

Now this works fine going down in size but when going up in size, this happens:
