Journal ArticleDOI
Contrast Enhancement Based on Layered Difference Representation of 2D Histograms
TL;DR: A novel contrast enhancement algorithm based on the layered difference representation of 2D histograms is proposed, which enhances images efficiently in terms of both objective quality and subjective quality.
Proceedings ArticleDOI
Contrast enhancement based on layered difference representation
TL;DR: A novel contrast enhancement algorithm based on the layered difference representation is proposed, which represents gray-level differences at multiple layers in a tree-like structure and solves a constrained optimization problem to derive the transformation function at each layer.
Journal ArticleDOI
Power-Constrained Contrast Enhancement for Emissive Displays Based on Histogram Equalization
TL;DR: A power-constrained contrast-enhancement algorithm for emissive displays based on histogram equalization (HE) that can reduce power consumption significantly while improving image contrast and perceptual quality is proposed.
Proceedings ArticleDOI
Multiple random walkers and their application to image cosegmentation
TL;DR: A graph-based system to simulate the movements and interactions of multiple random walkers (MRW) is proposed, and the repulsive rule for data clustering is developed, illustrating that the MRW clustering can segment real images reliably.
Journal ArticleDOI
Video Stabilization Based on Feature Trajectory Augmentation and Selection and Robust Mesh Grid Warping
TL;DR: A video stabilization algorithm, which extracts a guaranteed number of reliable feature trajectories for robust mesh grid warping and reconstructs videos more stably than the conventional algorithms.
