| Abstract: | In order to improve the contrast of infrared image,a method of homomorphic filtering for image enhancement is proposed. By use of the method, the influences of noises are reduced and the contrast and quality of original images improved. A good foundation is built in order to collect the characteristic information in the images further. The computer simulation and experiment results show that homomorphic filtering is an efficient method for contrast enhancement of infrared images. |
