Abstract :
Wavelet transform has widely applied in image denoising, and how to select the threshold is the key to wavelet image denoising. The paper put forward the algorithm for image denoising based on harr wavelet transform. First, The image with noise is decomposed by Haar wavelet transform, then select the soft threshold to clean the image noise. Experiments show that the algorithm can reduce image noise effectively and improve the detail effect of picture and raise the PSNR value of image.
