error in lip detection algorithm of my matlab code

Question

I am getting error in my Matlab code. I am using R2009b version

Frame index must be a numeric value greater than zero and less than or equal to the number of frames in the file.

Error in ==> mmreader.read at 74 videoFrames = read(getImpl(obj), index);

Error in ==> testing at 10 Ii=read(mov,k*10);

Answer 1

Just a hunch, but I'm guessing that your frame index is not:

a numeric value greater than zero and less than or equal to the number of frames in the file.

MATLAB is telling you that the error is happening in mmreader.read , and it is happening when you call mmreader.read at this point in your file testing :

Ii=read(mov,k*10);

If your movie reader object mov contains less than k*10 frames, or if k is zero or a negative number, you are asking MATLAB to do something impossible.

These sort of errors can be easily tracked down by typing dbstop if error at the command line, which means that when there is an error you enter debug mode. At this point you can then check what the value of k is, and also the number of available frames in mov .
