hello,
Can we display transformed image in cartesian plane according to image's rotation or shear? iF yes, then how can we do this?(I want to display a rgb image not its color pixels )
Any help would be appreciated.

You're passing in a color image and imhist() is not set up for that. If you want 3 histograms, extract each color channel independently,
% Extract the individual red, green, and blue color channels.
redChannel = rgbImage(:, :, 1);greenChannel = rgbImage(:, :, 2);blueChannel = rgbImage(:, :, 3);like in the attached demo, and histogram each color channel one at a time. Or if you don't care which color channel, then just lump them all together with (:)
imhist(rgbImage(:));A grayscale image with a colored contour plot superimposed:
% Make some sample grayscale image
I = abs(sin((1:500)'/100)*sin((1:500)/100));% Convert the grayscale image to RGB
Irgb = cat(3,I,I,I);% Plot the image and some contours in color
image(Irgb)hold allcontour(I);
