Comparative Study on Infrared Image De-noising Based on Matlab

As the significant link of the image preprocessing, image denoising has an effect on subsequent research work that cant be ignored. Infrared image de-noising based on the Matlab digital image processing environment is studied. The infrared image with different noises by different algorithms, such as average filtering, median filtering, multi-image average de- noising algorithm, low pass filtering and wavelet transform de-noising algorithm, are analyzed and processed. At last, via analyzing these algorithms for different noises and their owe characteristics comparatively, a suitable and effective de noising algorithm for the infrared image of electric power transmission line fault is found.
