Genetic Algorithm Framework for Image Block Clustering

Jyh-Horng Jeng, Chih-Wen Wang

Abstract


Principal Component Analysis (PCA) for image coding suffers the difficulties of computation complexity and projection errors. A typical method to solve this problem is the usage of clustering which partitions the image blocks into groups of smaller sizes. Moreover, the individuals belonging to the same group should exhibit the same visual properties such as edges and textures. In this paper, the genetic algorithm (GA) is adopted as a framework in the clustering process with visual properties imposed in the fitness function. Under such mechanism, the proposed method can effectively increase the retrieved quality and preserve the visual effects.
