MATLAB: Shadow Removal Using Intensity Surfaces and Texture Anchor Points

enhancementImage Processing ToolboxMATLABsegmentationshadow detectionshadow removal

I am working on removal of shadows from a single image.The shadows from the image must be detected first and then it has to removed. Currently i am using region growing technique for detecting the shadow. Is there any other method for this? plz help me out..

This seems more like an image processing question than a MATLAB question. Maybe you should try the sci.image.processing newsgroup, because there's nothing "built into" MATLAB to do shadow removal. If you have some question about code, for example you coded up this algorithm: http://www.cs.huji.ac.il/~danix/ShadowRemoval/index.html then this forum might help you with coding questions.

MATLAB: The code is unreachable.

INIT_DETECT is always false, thus the first branch of the if-statement cannot be reached.

MATLAB: Converting video frames into image file using vision.VideoFileReader

videoread = vision.VideoFileReader('YourFile.avi');
i = 0;
hold on
while ~isDone(videoread)
    i = i + 1;
    frames = step(videoread);
    imwrite(frames,['Image' int2str(i), '.jpg']);
    im(i)=image(frames);
    drawnow()
end
release(videoread)

However, I do would recommend you consider removing the image() call, as you would simply be putting image on top of image. It would make more sense to,

videoread = vision.VideoFileReader('YourFile.avi');
i = 0;
hold on
while ~isDone(videoread)
    i = i + 1;
    frames = step(videoread);
    imwrite(frames,['Image' int2str(i), '.jpg']);
    if i == 1
      all_images = frames;
    else
        all_images(:,:,:,i) = frames;
    end
end
release(videoread)

after which you could

implay(all_images)
