Catfish PSO Based Enhancement for Digital Mammogram Images

摘要

ZJn medical field, breast cancer detection at early stage is a cumbersome task. As a first step, the images have to be enhanced, which is the most crucial pre-processing step. Many methods that exist today for image enhancement are based on histogram of the image. In this paper, we propose a novel Catfish Particle swarm Optimization (PSO) algorithm based image enhancement techniques used for image enhancement that can be used for breast cancer image enhancement or mammography enhancement. The results are compared with Classical Histogram Equalization (HE) technique and Particle swarm Optimization (PSO) algorithm. The result proves the superiority of the proposed technique.
