I am using an indexed image.How do I programatically obtain the pixel intensity values obtained by changing the colormap to hsv in the imtool? Is there a way to change the colormap of the indexed image to hsv(256)?
I am new to MATLAB, kindly help!
I have attached the image below:

Which channel does the imtool display and what does the value ’91’ in the imtool stand for? How do I obtain this value?
The Pixel info at the bottom displays the following information:
Pixel info: (X, Y): Pixel Value
Here, we have pixel value of 91 at (309, 510). 91 is the pixel intensity in a range of values (mostly 0 to 255). Only 1 channel is being read because it is a grayscale image.
You can create a hsv image out of an RGB image but it doesnt make sense to talk of a hsv conversion for a gray scale image. What you have is a grayscale image.
