| Abstract: | As the disadvantage of lower contrast and the existence of noise in practical infrared images, combined with human visual characteristics, an infrared image enhancement method on wavelet transform and adaptive histogram equalization is used to enhance the infrared image based on the existent image enhancement method. The problem of the low contrast in the infrared image is not only solved,but the noise of the image is also reduced, and the image detail is also highlighted. |
