hi I have an image of face that I devided it into 3 RoIs and now I want to apply analysis of vertical histogram(showing the intensity differences between successive rows,pixel-wise) and horizontal histogram(showing the intensity differences between successive columns,pixel-wise). if anyone know how we can obtain the vertical and horizontal histogram of an image?

What about
[countV, binValuesV] = hist(diff(yourImage, 1, 1))
[countH, binValuesH] = hist(diff(yourImage, 1, 2))

I need to draw horizontal and vertical histogram of my image to identify the rectangular ROI region. I used your function. But, it's showing error. What to do?

The poster wanted differences, and you don't. See answer to your question here: https://www.mathworks.com/matlabcentral/answers/422483-how-to-draw-vertical-and-horizontal-histogram-of-an-image#answer_340060

plot(mean(image))
plot(mean(image,2))
I think its what you're asking for, but its not really a histogram though.
