When you convert this image to grayscale, you then need to only store a single 8 bit value per pixel for the grayscale value. You go from 24 bits per pixel down to 8 bits per pixel, so your grayscale images will be a mere 33% the size of the originals. Besides saving you a ton...

A grayscale image, sometimes referred to as anintensityimage, is stored as anm-by-ndata matrix,X, whose values represent intensities within some range. A grayscale image is represented as a single matrix, with each element of the matrix corresponding to one image pixel. While grayscale image...
