| Abstract: | First the image is transformed with dual tree complex wavelet to get the sub-band image at different scale and then the sub-band image is processed with nonlinear diffusion.The advantages of both the nonlinear diffusion and dual tree complex wavelet transform are used to obtain the edges and texture of the image and check the noises. |
