videovideo processing

I am working on project which involve image processing on video files.All my codes are working fine.But,sometimes,when i am executing my program,matlab and my system hangs and program stop responding to my commands.I suspect it may be due to main memory getting overloaded.Is there any way,in which i can keep flushing main memory as one action is completed?

Best Answer

"clear" variables when you are finished using them.

If you are using virtual memory or swap space, you might want to reduce that so that the program runs out of memory and gives an error instead of using the (very slow) disc as memory.

MATLAB: Displaying a difference image as a video

After the loop,

mymovie(1:numFrames).cdata = deal(temp{:});
mymovie(1:numFrames).map = [];

then you can

movie(mymovie)

If you want to write the movie out to disk then if you have 2010b or onwards, consider using the new VideoWriter class. Otherwise,

aviobj = avifile('MyMovie.avi');
aviobj = addframe(aviobj, temp{:});
close(aviobj);

Caution: your sFrame and pFrame are most likely of unsigned integer data type, so when you construct the difference image, the place where the second image is greater than the first would want to go negative but cannot due to the unsigned data type; negatives will be replaced by 0 in that case. That might not be what you want, so you might have to change the data type and rescale the data and then translate and rescale the difference image. There is an Image Processing Toolbox command that will change the data type and rescale for you, but I have forgotten the name of the command.

MATLAB: Storing images in matrix

Your ImgR will be an array. What does Predicted_Function do with array inputs? If it returns an array, then you are expecting to store that array in the single location NewFrames(c,r).

Perhaps you want,

NewFrames(c,r).cdata = NewFrame;
