Sir, I am doing fruit classification system.I finished preprocessing and segmentation using k-mean and thresholding. I think to use HSV color space for color feature. I want to know how can I calculate hsv value for the object of interest (fruit image). I find hsv value but I got the value of the whole image including background. Thank you so much,sir.

What about multiplying the x value by 360?
If you ask an internet search engine for images concerning "hue 0 to 360" you find many examples: bars, lines, polar diagrams. So what do you want?
Add this to your segmentaiton code:
% Get the aspect ratio of each blob.
props = regionprops(mask, grayImage, 'MajorAxisLength', 'MinorAxisLength', 'Area');aMajor = [props.MajorAxisLength]aMinor = [props.MinorAxisLength]allAreas = sort([props.Area])aspectRatios = aMajor ./ aMinornumBlobs = length(props)cmap = zeros(numBlobs+1, 3);for k = 1 : numBlobs if aspectRatios(k) > 2 % Whatever value you want.
cmap(k+1, :) = [1, 0, 0]; % Red.
else cmap(k+1, :) = [0, 1, 0]; % Green.
endendcmaph3 = subplot(2, 2, 3);labeledImage = bwlabel(mask);imshow(labeledImage, []);colormap(h3, cmap);
Note: my segmentation is not good because it didn't find the lower right washer nice and the screw and the washer are touching and I didn't try to separate them. But the colormap code works well.
