Simplified Implementation of Histogram Equalization Using Approximation Offset

This paper presents a simplified implementation of Histogram Equalization by adding offset values to the Histogram bins. The proposed approach helps to simplify the division/multiplication operations in Histogram Equalization calculation using shift operations. This approach is tested on different resolutions of gray images. The image quality comparison of this approach with conventional Histogram equalization shows that the proposed simplified implementation is effective for lower values of approximation offset.
