Hello,
I have genereted H, S and V histograms of two images. Anyone can give me suggestion for how to compare them for similarity. I have used the below code
rgbImage = imread('0.JPG');
rgbImage2 = imread('1.JPG');
hsvImage = rgb2hsv(rgbImage);
hImage = hsvImage(:, :, 1);
sImage = hsvImage(:, :, 2);
vImage = hsvImage(:, :, 3);
hsvImage2 = rgb2hsv(rgbImage2);
hImage2 = hsvImage2(:, :, 1);
sImage2= hsvImage2(:, :, 2);
vImage2 = hsvImage2(:, :, 3);
figure;
subplot(2,2,1);
hHist = histogram(hImage);
grid on;
title('Hue Histogram');
subplot(2,2,2);
sHist = histogram(sImage);
grid on;
title('Saturation Histogram');
subplot(2,2,3);
vHist = histogram(vImage);
grid on;
title('Value Histogram');
subplot(2,2,2);
imshow(rgbImage);
subplot(2,2,3);
hHist = histogram(hImage2);
grid on;
title('Hue Histogram');
subplot(2,2,2);
sHist = histogram(sImage2);
grid on;
title('Saturation Histogram');
subplot(2,2,3);
vHist = histogram(vImage2);
title('Value Histogram');
subplot(2,2,4);
imshow(rgbImage2);
Thank you.

missing the code.
If your image sizes are equal, then you can compare them directly. Example, img_1 == img_2. If not you may want to scale.

Perhaps you just want to take the mean and standard deviation of each histogram. Why don't you look into CBIR papers to see how they do it?
