GNC function fails #32

Closed renedlog closed 3 years ago

renedlog commented 5 years ago

The GNC function fails due to YCBCR image is out of the Valid range caused by:

b = ycbcr + sqrt(level)*randn(sizeA);

and fails at the next step:

b=ycbcr2rgb(b)*255;

error: ycbcr2rgb: input must be a colormap (Nx3) or RGB image (NxMx3)
error: called from

Have you solved it? I couldn't replicate the error as you reported. Is it related to MATLAB version?
