LogiCORE IP Image Statistics v5.01a, v6.0 - Why is the Image Statistics core histogram output less than the total number of pixels in the image?

Description

Why is the Image Statistics core histogram output less than the total number of pixels in the image?




Solution

This is a known issue in the Image Statistics core v5.01.a and v6.0 that has been resolved in the Image Statistics core v6.0 (Rev. 1) and later available in Vivado 2013.2 and later.

The problem is demonstrated by the fact that the sum of the R,G,B Histogram values is not equal to the total pixels present in the image.
