Genetic algorithm （GA） is a random search and optimization method based on natural selection and genetic mechanism of the living beings. In recent years, GA is used successfully in solving the complex optimization and the industrial engineering problems. Therefore, the research on GA has attracted a lot of attention. This paper discusses and surveys the status and advances in GA research, The basic algorithms, theory, implementation techniques of GA are outlined first. Then many applications of GA in image processing field are reviewed, such as image segmentation and edge detection, image compression, image restoration, image matching, image enhancement, and image reconstruction. At last, several key problems in this field are discussed as well as their development in the future.
