In the embedded video image processing system,the quality of enhanced image and the speed of image processing are the key points to improve the algorithm efficiency,and the reasonable combination of appropriate algorithms of image enhancement with efficient hardware platforms is a good way to solve the problem. In this paper,different kinds of image enhancement algorithms are researched and three typical enhancement algorithms,namely,histogram equalization,homomorphic filtering and wavelet transform,are simulated on a Matlab platform. Then,the simulation results are analyzed and their advantages and disadvantages are compared. Finally,it gives the best scene for the application and optimum implementation of hardware platform of each algorithm. Moreover,it points out that it will be a developing trend to integrate the advantages of various algorithms to practical applications to image enhancements.
