opennotescanner's Introduction

OpenNoteScanner

This little application provides a way on scanning handwritten notes and printed documents.

It automatically detect the edge of the paper over a contrastant surface.

When using the printed special page template it automatically detects the QR Code printed on the bottom right corner and scans the page immediately.

After the page is detected, it compensates any perspective from the image adjusting it to a 90 degree top view and saves it on a folder on the device.

It is also possible to launch the application from any other application that asks for a picture, just make sure that there is no default application associated with this action.

Usage

See the FAQ.

Requirements

Because of the version of OpenCV that is used in the project it needs to run on Android 5.0 (lollipop) or newer.

In order to capture and manipulate images Open Note Scanner depends on having the OpenCV Manager application installed. If not installed Open Note Scanner will ask to download it from https://github.com/ctodobom/OpenCV-3.1.0-Android or from Google Play Store.

How to Install

Open Note Scanner is available for simplified installation on Google Play Store, from Amazon App Store and also from F-Droid Android Open Source Repository.

Disclaimer: Google Play version is ad-supported.

Binary APK file is available directly from GitHub in the releases section of the project.

Instructions for building

Android Studio

Import the project from GitHub using File -> New -> Project from Version Control -> GitHub, fill the URL https://github.com/ctodobom/OpenNoteScanner.git

It will ask for a base directory, normally AndroidStudioProjects, you can change it to your preference.

After this the Open Note Scanner can be built.

Command Line

Go to your base folder and import it using git:

$ git clone https://github.com/ctodobom/OpenNoteScanner.git

This should import the Open Note Scanner repository in OpenNoteScanner folder

You need to point the environment variable ANDROID_HOME to your Android SDK folder and run gradle to build the project:

$ cd OpenNoteScanner
$ export ANDROID_HOME=~/android-sdk-linux
$ ./gradlew assembleRelease

Instructions for Contributing

If you're new to open-source, we recommend you to checkout our Contributing Guidelines and Setup Guidelines. Feel free to fork the project and send us a pull request.

History

I've started this app on a brazilian holyday "extended weekend" based on the fact that I was unable to find any open source application that does this job. I was mainly inspired on the RocketBook Wave closed source application.

I really do not know if I will extend more the application, but I am writing bellow some objectives to make it better.

Roadmap

enhance the image gallery of scanned documents
register a share action in order to obtain documents already pictured through standard camera apps
implement automatic action based on the RocketBook Wave marking of the page

Donations

My job is on enterprise servers administration and some development consulting. I do collect money from my customers. I am well paid for that.

For being part of open source projects and documenting my work here I really do not charge anything. I am trying to avoid any type of ads also.

If you think that any information you obtained here is worth of some money and are willing to pay for it, feel free to send any amount through paypal or bitcoin.

Paypal	Bitcoin

In order to fund the development of Open Note Scanner, since version 1.0.36 when downloaded from Google Play store the app will show ads on some screens and will also allow for donation through Google Play in-app purchase. There is no difference on the features available from Google Play version and F-Droid releases.

Contributing

If you have any idea, feel free to fork it and submit your changes back to me.

opennotescanner's Issues

Bad quality?

I managed to get a couple of pictures, but only after turning on the flash (maybe you shoud lower the contrast treshold).
Anyway, the captured pictures are at very low resolution and the text is unreadable (11pt on A4, fairly standard).
Am i missing something?

I believe it might be trying to perform an animation on an image that has been deleted.

feature req: add option to change location of images

It would be nice to be able to change the default directory for ONS' image files.
As @ctodobom told me on the telegram-chat
ONS folder is hardcoded right now.

Future request. Automatic sharing.

like a RocketBook.
For example, tag "Rocket" - sending image to e-mail.

Won't capture images

Hi. I'm a big fan of camscanner so when I saw you had a FOSS app that did something similar I was super excited.

I have a Sony Xperia Z1 compact with Android 5.11 - stock rom.

I installed v1.0.10 OpenNoteScanner from f-droid, and let the app install openCV manager from google play. When I launch the app I get the camera preview, I can toggle the buttons on the right, but I can't capture anything. I have tried tapping the blue shutter icon and the screen, and the feedback indicates it registers taps, but nothing happens.

Any ideas?

Thanks

App Status

Is the application still in development?

The idea behind the application is really brilliant but the app does not seem to evolve. I have found all the issues that have been reported one year ago.

The most important are:

Bad quality;
Document recognition failure;
PDF template icons unmanaged.

Thank you so much for work you've done!

Focus problem on some devices

Reported on Sony Xperia SP by @SparkyCola on Telegram group

Looks like camera looses focus on the right moment of takePicture action.

Nexus 7 (2013) no focus (auto or manual)

When I'm trying to take photo of some document I can't capture it properly because I can't focus it properly. It is just stuck on one level and larger documents are often blurry and text is not recognised

App crashing on Marshmallow samsung tablet(sw600dp)

Threema incompatibility ("is no image file")

After an crash when opened via Threema (#33) there is still an issue when opening the app via

Now I can shot the photo, but when it is returned to Threema I just see a broken image:

When I tap to send it, it says "The selected file is no image file". So some metadata/file type seem to missing...

Crashes when loaded from another app

I have another all which allows you to chose "camera" for sharing photos. There you chose the camera so and the camera so sends the picture back to the app for further processing.
However when I choose your app there it always crashes after I take a photo.

App Crashed when "Storage" permission is revoked.

When the "Storage" permission is revoked ("Camera" permission is granted) the app crashes. (see the gif below).

IMHO, the APIs for checking(checkSelfPermission) Storage permission should get called just before saving the picture.

Create a better icon and banner

The current Icon / Logo is a mockup of three different icons. The Google Play banner is very amateur.

It is needed to create a new High Resolution logo (512 x 512) as well as the application Icon on all its versions mdpi to xxxhdpi mipmaps, and maybe a vector drawable one.

The Google Play banner would be nice to improve too. The official size is 1024 x 500 px and it would be featured on the initial page of the project too.

Obviously to say that the Green color used in the app must be the main one used on the arts (#00E676).

Possibility to update images based on same page?

Hello guys!

First of all I want to say CONGRATS on this great app.

I know that you're working on current features to be stable and fully working in order to process more features but I'd like to point out a new possible feature that will be update the image if we make changes on the page.

Eg. I draw a circle on a page and I process it with the app, once I draw a triangle on the same paper sheet it would automatically update existing and processed image(I guess it would take a reprocessing of the image) .

Regards.

should i be able to download/build dependencies w/single command?

Hi, I'm using gradle --version 2.10, and trying to figure out how to build this project and its dependencies. Do these issues sound specific to gradle version or some step I'm missing/didn't see in the README?

I get the following (regardless of arguments) when calling ./gradlew:

Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain

and when I run my own gradle (2.10):

ANDROID_HOME=/path/to/my/sdk gradle assembleDebug

I get: https://dpaste.de/juge/raw/ tl;dr "can't find java libraries" eg: FullScreenViewActivity.java:8: error: package android.support.v4.app does not exist

I seem to recall gradle does this automagically as needed. Are these dependencies just not declared in a build.gradle somewhere or am I misunderstanding?

Gallery looks strange

My gallery in Open Note Scanner looks like this:

Fail to open large image from the gallery

In some phones an out-of-memory error occurs when trying to open a large image from the gallery, or navigate sliding the fullscreen viewer to a large image.

This error occurs on phones where the OpenGL surface allows 4096x4096 images.

Icons and dimensions of page template

Is it possible to get the icons and the dimensions of the page template so I can create a bigger template?
Does it meet any specification on icon size percentage base on the paper dimension?

Or at least have another A4 page template with let's say A4 one page?

Regards.

mention location of stored files

I'm having a hard time right now finding out where the stored images are.

I expected to have a "details" view or something on each image. Or a settings dialogue where I can see the storage path.

OpenNoteScanner does not recognize the document

Hi, I'm using this app from a Nexus 6 with Android N. Everything seems to be working fine, but the app does not recognize the borders of the document I'm trying to scan (an a4 paper on a table with good contrast). I have to "scan the whole image", that of course it not optimal.

FR: Manual perspective pinning

It would be great if this app also offers manual corner pinning like most scanning apps offer.

thanks

Slow Scan

Open Note Scanner it's good, but it's very slow because you're trying to dynamically recognize images, before the photograph is taken - like the human brain does, which on not high end devices tends to be tediously slow. On the other hand, apps like CamScanner work blazing fast because they recognize a still image ( after photographing ) .... I'd request the devs to add an option for static image recognition.
Thank You.

feature request. Detect book pages

It would be great to detect two book pages on contrast surface and split them up and store both of them into two separate files.

image for example:

Inefficient API is used

Dear developers,

I found an inefficient API, setImageURI(), is used in OpenNoteScanner.

For setImageURI(), Google says this:
https://developer.android.com/reference/android/widget/ImageView.html#setImageURI(android.net.Uri)
" This does Bitmap reading and decoding on the UI thread, which can cause a latency hiccup. If that's a concern, consider using setImageDrawable(android.graphics.drawable.Drawable) or setImageBitmap(android.graphics.Bitmap) and BitmapFactory instead. "

I noticed that in the following code, setImageURI() is used:
com.todobom.opennotescanner.views.TouchImageView.java (line number: 181)
https://github.com/ctodobom/OpenNoteScanner/blob/master/app/src/main/java/com/todobom/opennotescanner/views/TouchImageView.java

Do you think the use of setImageURI() will affect OpenNoteScanner's performance? If so, maybe we should move Bitmap reading and decoding to a background thread.

Thanks.

Gallery selection doesn't show correct after scroll

When scrolling the gallery with some selected items, new items appears as selected.

Camera upside down

Hi!
This app is great! :D

But I have a small issue... I am on Nexus 5X with Android 7.1.1, and the camera is shown upside down in this app.

Do you have any idea why?

I am not a Android dev, but if you point me in the right direction I can try to work on this too :)

Feature request: manual edition

I'd like an option to manually cut the photo and adapt it to the size of my screen. This is very useful if you take a photo with an angle or you just need a paragraph from an entire page.

feature request. Merge few images into one pdf

I used ImageMagick's convert utility before for processing multipage documents with morphology and merging to pdf. That useful, but requires an regular OS, but it would be great to do all operations instantly inside your app.

Captured image dark.

Could you please help me?

Aggressive post processing

I like this app because I can use as camera replacement for scanning documents but for that purpose I find the post processing on images to be super aggressive such that most of the images I take with it are not even readable at all, fonts are gone, images are gone etc. I even tried the color mode, but that just gave the same result as the bw mode not sure if it is buggy. I tried the auto on off without any success.

Anyways it would be great if one could levrage the level of the processing a bit.If people want super auto mode that is fine but I personally like to use this to scan documents, receipts, napkin notes etc

I use the latest Fdroid version on CM12

thanks

Handle apps that passes content provider URI

Problem explainded by @mimiks at #33 (comment):

Some apps may provide an URI that refers to a content provider rather than a file. In that case, the URI scheme starts with content:// rather than file:// and fileUri.getPath()(line 870) will not return a file path.

A comprehensive example of how to get the path from file-based content providers can be found here: FileUtils.java

Permanent translation issue

This issue will receive a new comment every time I change something on the strings of the project, in order to inform translators about the pending work.

For now we have translations to:

Portuguese (by myself)
Italian (by @Claudinux )

Google Play statistics tells that there are major use on people that speaks German, Spanish and French also, and, I know that there is a lot of activity on Asia and middle east.

Any help on translating to those languages is appreciated.

[Enhancement] Detect and fix folds

When a paper has been folded in two or four, it can be hard to make it flat.
That results in non-rectangle shapes, that could maybe be detected and corrected?
Very low priority.

Wrongly asks for READ_PHONE_STATE permission

It was unintentional, placed on the manifest by Android Studio

Reported on a comment by Rapunsel Jensen on the Linux Magazine article ( http://goo.gl/xWdqJD )

Need removal of the permission

[Request] Provide apk binary

I have been looking for such an open-source application and would like to test yours. Would you please provide the apk binary in the “Releases” section or publish your app to F-Droid?

Thank you.

Can't install on Android 4.2.2 phone

Hi,

I just wanted to try the latest release and copied the APK to my Android 4.2.2 phone.
When I try to open the APK it says "can't parse file". Any idea why that is?
Is it even compatible with Android 4.2.2?

Greetings
