- W2350443802 abstract "Image denoising is a front subject of signal processing.Contourlet transform approximates source image with a group of infra architecture similar to line segment.Aiming at the multi-scale and multi-directional of Contourlet transform,a new self-adaptive and multi-threshold method of denoised images with combined soft threshold function and hard threshold function was put forward.This method fully considers the texture,scale and direction of image,and holds the excellence of soft threshold function and hard threshold function.A higher signal-to-noise ratio and better visual effects can be obtained,the information of the image texture is maintained,and finally an excellent denoising result is obtained." @default.
