backProjectHistogram :: [Image GrayScale D8] -> Histogram -> Image GrayScale D8

Given a set of images, such as the color channels of color image, and a histogram with corresponding number of channels, replace the pixels of the image with the likelihoods from the histogram

histogram :: [(Image GrayScale D8, Int)] -> Bool -> Maybe (Image GrayScale D8) -> Histogram

 Calculate an opencv histogram object from set of images, each with it's own number of bins.
