High frequency sub-band images were denoised by mean filtering using different filter templates, and low frequency approximation image remained unchanged in this process. Then the denoised-image was obtained by composing the low frequency approximation images and the high frequency detailed images with mean filtering. Experimental result shows that the noise is effectively removed and the detail of the image is well preserved. This method has better denoising effect than single BEMD method and mean filtering method and the method combining wavelet transform with mean filtering. %K image denoising %K wavelet transform %K bi-dimensional empirical mode decomposition %K mean filtering
