Hello, I am trying to convert an rgb image to hsv.
I made the following steps:
1.make the image [MNx3]
2.multiply with the opponent coords
3.increase the saturation
4.apply Inverse transform to go back to rgb
5.Gamut mapping
6.Redo Display Gamma
Now i have an array MNx3
My problem is that i cannot display the image as it is. It displays a line. How can I convert that to an image??
Any help??

What does "[MNx3]" mean? Images have usually a size of [M x N x 3]. And how do you try to display the image? Please post the exact code instead of a description.

does the rgb2hsv function not work?
I do it that way...,
hsvimg = rgb2hsv(rgbimg);
... do something ... (like saturation increase)
rgbimg = hsv2rgb(hsvimg);
