I wish to do thresholding operation on a HSV Image converted from an RGB image. Is there any function like imtool()for RGB images that display the HSV Values of a pixel?

Yes. My demo "Simple color detection by hue" in my File Exchange does that. http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 Also there is an interactive thresholding application.

You can use impixelinfo() to have the value of the three channel image that's being displayed show up in a little static text box as you mouse around. The image can be RGB, grayscale, or HSV. Let me know if you can't figure it out. You may have to play around with the 'Position' option to see the text.

No. What original HSV values? As far as I know there is only one hsv image, and it has values between 0 and 1, like it should. Exactly what are you expecting?

channel1Min = 0.825;
channel1Max = 0.451;
% Create mask based on chosen histogram thresholds
sliderBW = ( (H(:,:,1) >= channel1Min) | (H(:,:,1) <= channel1Max) );
BW = sliderBW;

You can use the Color Thresholder app on the Apps tab of the tool ribbon to interactively threshold the color image by moving sliders.
