Evolutionary algorithm-based local structure modeling for improved active shape model

Abstract

An evolutionary algorithm-based robust local structure modeling technique is proposed to improve the performance of the active shape model (ASM). The proposed algorithm can extract boundary of an object under adverse condition, such as noisy corruption, occlusions, and shadow effect. The principle idea of the evolutionary algorithm is to find the global minimum of an objective function by evolving from a large set of populations rather than a single solution which may cause a local minimum. The proposed algorithm has been tested for various images including a sequence of human motion to demonstrate the improved performance of object tracking based on the evolutionary ASM.
