A New Method for Image Contrast Enhancement Based on Automatic Specification of Local Histograms  
Summary The histogram equalization (HE) method is widely used for image contrast enhancement. While it can enhance the overall contrast, the inherent dependence of its transformation function on the g......

Edge sharpening through ramp width reduction  
Edge sharpness is very important to the visual quality of an image. Most commonly adopted methods increase the contrast of the edges to achieve sharpening. However, for wider ramp edges, increasing co......

AUTOMATIC CONTRAST ENHANCEMENT BY HISTOGRAM WARPING  
We present an automated algorithm for global contrast enhancement of images with multimodal histograms. To locate modes and valleys, histogram analysis is performed by kernel density estimation, a rob......

Contrast Enhancement and Intensity Preservation for Gray-Level Images Using Multiobjective Particle Swarm Optimization  
The contrast enhancement of gray-level digital images is considered in this paper. In particular, the mean image intensity is preserved while the contrast is enhanced. This provides better viewing con......
