Please explain how to obtain the hue of a colored image in MATLAB

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

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
