Efficient Method for Image Enhancement using Non-Uniform Revisory and Exact Histogram Equalization

Rupneet Kaur Hanspal ^[2] | Kishor Sahoo ^[2]

Abstract: This paper presents the Image Enhancement using Non-uniform Illumination Revisory and Exact Histogram Equalization. This technique is hybrid technique, which is a combination of two individual contrast enhancement techniques. One is Non-Uniform Illumination and the second one is Exact Histogram Equalization. Here Non-Uniform Illumination is used for to correct the illuminance and to differentiate the background and foreground in image. And Exact Histogram Equalization is used for the contrast enhancement.

Keywords: Image Enhancement, Non-Uniform Illumination, Morphological Operators, Erosion, Dilation, Opening, Closing, Exact Histogram Equalization, Contrast per Pixel CPP, Variance Value, Mean Value, etc
