Hello.

I am working on a code named Demo_SR via this link https://github.com/tingfengainiaini/sparseCodingSuperResolution.

I tried to rename the images on the Testing folder to suite image list. I obtain the below error each time I run the code.

I really wish to know why and how to resolve this.

Thanks

Error using rgb2ycbcr>parse_inputs (line 127)
MAP must be a m x 3 array.
Error in rgb2ycbcr (line 49)
rgb = parse_inputs(varargin{:});
Error in Demo_SR (line 41)
    im_l_ycbcr = rgb2ycbcr(im_l);

You forgot to completely fill out the form when you posted, or chose not to. So we don't know what release you have. Evidently your release of MATLAB expects rgb2ycbcr() to have a colormap as it's input, and does not allow images, if that is what im_l is. New versions of MATLAB will take an rgb image so make sure that's what you're using and what you're passing in. At line 41, insert this and tell us what it says

whos im_l

It should show rows by columns by 3.

So you have a gray scale image, not a true color RGB image. So it doesn't really make sense to ask for Cb and Cr images. Your gray scale image is just the Y image. Do you (incorrectly) think your image is color? It is not.
