runtime errors

[antithing]

Hi, and thank you for making this code available. I know you have not updated it for a while, but if you have a minute, could you help me to get it running?

It builds fine, but when i run it with:

matting.exe grad 1000 .\05.ppm .\05_scribs.pgm .\05_gt.pgm

I get: Error: read 61183/441600 pixels.

Is this code functional?

Also, is it possible to run it on cv::Mat images, instead of the ppm reader?

Thanks again.

You're on Windows, which has absolutely bizarre behavior regarding file reading and writing. I'll bet $100 that if you change the fopen() calls to have argument "rb" instead of "r" in ppm.h, this fixes your problem.

If you have other problems, try getting hold of a Linux box if you can.

Ah, thank you! this has solved the issue, and the code will now run. However, i am getting strange results. From the files you include with the code, the ground truth looks like:

When I run:

matting.exe grad 1000 .\05.ppm .\05_scribs.pgm .\05_gt.pgm

I get an alpha result like:

What could be going wrong here?

thank you again.

Hi, thank you for making gpu acceleration. However, I got some problems. If you have spare time, can you help me with these problems? My configuration is ubuntu 16.04, cuda 10, gcc 5.4.0, cmake 3.5.1, which is not the same with your settings.

when It builds fine, but when i run it as your instruction: I get: Laplacian generation: 7.44e-01s 441600
