+Note:
+The input folder contains one image from Van Hateren's natural image database
+(http://www.kyb.tuebingen.mpg.de/?id=227). Image pixels are 12-bit depth. Thus,
+for calculation of the B-bin histogram of an image, the corresponding histogram
+bin is computed as ((pixel * B) >> 12).
+Monochrome images from other databases or synthetic images can also be used. The
+read input function (in main.cpp) might need to be changed accordingly. If image
+pixels are b-bit depth and the histogram contains B bins, the histogram bin will
+be computed as ((pixel * B) >> b).
