Hi,

U can use the rgb2hsv function in MATLAB to convert an RGB image HSV (hue, saturation, value). The resulting image will be of class double.

U can then use hsv2rgb function to convert the HSV image back to RGB. The input image must be of class double.

Hope this works

Regards

WT

Hello, Try using rgb2hsv command. this command will give you hue ,saturation and value components ie 3 dimensional matrix, use the first matrix which contains hue. here is the small code. >> IM=imread('sunflower.bmp'); >> HSV=rgb2hsv(IM); >> HU=HSV(:,:,1);%HU is hue component --- lowtechorhightech <lowtechorhightech@lowt...> wrote: > Please explain how to obtain the hue of a colored > image in MATLAB __________________________________
