Return image data associated with movie frame
[X,Map] = frame2im(F)
[X,Map] = frame2im(F) returns the indexed image data X and associated colormap Map from the single movie frame F. The output Map is a three-column matrix where each row of the matrix is an RGB triplet value that defines one color of the colormap. If the frame contains true-color data, then Map is empty. The functions getframe and im2frame create a movie frame.
