Hi

Is it possible to compile this on windows ?

thank you

Hello,
Could someone provide instruction about how to build it in anaconda environment, in windows 10? After clone the directory locally, the command 'python setup.py build' ends with error:

running build
error: [WinError 2] The system cannot find the file specified

Does that mean the setup.py is not calling conda-build? then how to build?

Thanks

Hello @bwsw,

I will like to use some of your functions within another project of mine, but I am trying to understand how they work; especially the pack. I do understand it takes a bunch of rects which indicates the different contours found as motion, and combines them based on distance right?

I found myself in similar issues when building a project, and though I used non-maxima suppression to combine those that overlap, it didn't work for close ones and still led to having lots of disjointed contours. Looking at your pack code, I believe it will solve the issue for me.

So please I am asking if there is a way to explain a bit more what is passed into it. As I can't seem to get what the bins is all about. Then why the extra copy_images function.

I am sorry I don't really understand C code, so why the extra confusion. I know its a lot to ask, but understanding it will really help.I have spent a lot of time trying to, but to no avail.

Kind regards

I thought this lib was for Python3, but the C-code references PyInt_AsLong which is deprecated. Can you clarify?

I would like to try this lib on a Raspberry Pi 3, and as far as I see it, numba on that platform requires either that I use some special distribution "berryconda" which I never heard of before, or a very complicated compilation process. Is this lib strictly needed, and would it be possible to make a version that doesnt use it?

Hello,

Thanks for this nice code. Any plans to make it easily pip install-able? Will like to use it within a docker environment, but as it is now, for some reasons being difficult for me to install.

Tried using

pip3 install git+https://github.com/bwsw/rt-motion-detection-opencv-python

tells me

Hello, i got a problem when i try to follow your guide in step build the project:

rt-motion-detection-opencv-python# python3.7 setup.py build

running build
gcc -c src/scanner.c -o src/scanner.o -W -Wall -Werror -Wextra -fPIC -O3 `pkg-config --cflags python3` -Isrc -I`python3 -m site --user-site`/numpy/core/include
src/scanner.c:5:11: fatal error: numpy/arrayobject.h: No such file or directory
 # include "numpy/arrayobject.h"
           ^~~~~~~~~~~~~~~~~~~~~

Thank you for your work.

Best regard

@bwsw Hi, thank you for providing such a tool. However, there seems to be a bug for the lambda function you are using.

Exception has occurred: IndexError
list index out of range
  File "....../motiondetector.py", line 42, in <lambda>
    box_filter=lambda b: ((b[2] - b[0]) * (b[3] - b[1])) > 1000,
  File "....../packer.py", line 11, in pack_images
    if box_filter(b):
  File "....../motiondetector.py", line 37, in <module>
    results, box_map = pack_images(

It looks like when b is empty, b[0], b[1], b[2], b[3] are just meaningless..
I'm moving out the lambda function...

Cheers
Pei

I've made some experiments with your code and found out an error in packer.py:

box_map.append((b, (x, y, x + w, y + h), (rid[1], rid[0], rid[3], rid[2])))

should be

box_map.append((b, (x, y, x + w, y + h), (rid[0], rid[1], rid[2], rid[3])))

for correct mapping with original box coordinates.

when I run the make command on wondows 10 I get the following errors:

Hi,

I'm trying to test your algorithm, on mac os x, compiled the c parts successfully, Python 3.7.7
All required libraries installed.

I'm executing the program but I'm always getting segmentation fault 11.

UPDATE:

Added import faulthandler; faulthandler.enable()

I'm getting this:

I haven't changed the default values.

Hope you guys can give me a hand.

Hi, how do I use your code on Windows?

If I either try to run the setup.py build or call make I get this WinError 2.
