Fig. 6From: Algorithm-assisted diagnosis of Hirschsprung’s disease – evaluation of robustness and comparative image analysis on data from various labs and slide scannersMicrophotographs of ganglion cells and their immediate surroundings from each medical center along with RGB histograms. The images demonstrate differences in color, resolution and texture with corresponding differences in each color channel pixel value distribution as demonstrated in the histograms (expressed as the percentage of pixels corresponding to each pixel value). Each set of image and histogram "a" through "d" corresponds to the different medical centers A through D, respectivelyBack to article page
