Title: Contrast Context Histogram – A Discriminating Local Descriptor for Image Matching
Author: Chun-Rong Huang, Chu-Song Chen and Pau-Choo Chung

Abstract:
This paper presents a new invariant local descriptor, contrast context histogram, for image matching. It represents the contrast distributions of a local region, and serves as a local distinctive descriptor of this region. Object recognition can be considered as matching salient corners with similar contrast context histograms on two or more images in our work. Our experimental results show that the developed descriptor is accurate and efficient for matching.
