In this paper, an image-denoising method is presented based on mathematical morphology and wavelet transform. Highfrequency coefficients are processed by mathematical morphology firstly. Then, according to the respective characteristics, high frequency sub-band images at horizontal, vertical and angular directions are denoised by three different filter templates after wavelet transform. We take measures to protect edge information and detail of image. Experiment result shows that the noise of the image is removed effectively. At the same time, the detail of the image is kept well. The method has better denoising effect.
