Transform Coefficient Histogram-Based Image Enhancement Algorithms Using Contrast Entropy

Abstract: Many applications of histograms for the purposes of image processing are well known. However, applying this process to the transform domain by way of a transform coefficient histogram has not yet been fully explored. This paper proposes three methods of image enhancement: a) logarithmic transform histogram matching, b) logarithmic transform histogram shifting, and c) logarithmic transform histogram shaping using Gaussian distributions. They are based on the properties of the logarithmic transform domain histog… Show more

“…Local CE improves contrast by altering pixels in terms of local properties, and typically operates in the image transform domains, such as the discrete cosine transform (DCT) [4] and the discrete wavelet transform (DWT) [5]. Local CE can also be enforced by adaptively applying the global CE to local image regions [3].…”

“…The accelerated HE algorithm is proposed as follows, Comparing with the baseline HE algorithm [1], the integrated acceleration measures are included in the steps (1), (2), (4). Specifically, in the step (1), spatial image downsampling decreases the number of counted pixels, which can accelerate the generation of histogram.…”

“…In order to overcome the limitations of HE, several brightness preserving methods have been proposed (Kim et al, 2001;Chen and Ramli, 2003a;Sun et al, 2005;Chen et al, 2006;Wang and Ward, 2007;Sengee and Choi, 2008;Wang and Ye, 2005;Agaian et al, 2007). One of the popular brightness preserving methods is the mean Brightness preserving BiHistogram Equalization (BBHE) introduced by Kim (Chen and Ramli, 2003b).…”
