Effective Problem Solving Practitioners Guide Providing access to a variety of powerful mentoring resources and information on MENTOR s projects and initiativesRegarding the imhist (image) part, you might want to try converting the image to grayscale first (even if it was originally a grayscale image), as follows: newImage = rgb2gray (oldImage); After, you should be able to perform the imhist (newImage) without any problems. As understood, achievement does not suggest that you have extraordinary points. Just use any frame as the reference (I suggest using the first one, but there is no real reason to do so), and keep it for all the remaining frames. One issue with this approach is that when a 16-bit image is histogram matched to an 8-bit reference image with good contrast, the bit depth of the resulting image is still 8-bit.
