摘要：This Paper presents a wavelet-based multiscaleproducts thresholding scheme for noise suppression of magneticresonance images. This paper proposed a method based on imde-noising and edge enhancement of noisy multidimensionalimaging data sets. Medical images are generally suffered fromsignal dependent noises i.e. speckle noise and broken edges. Mostof the noises signals appear from machine and environmentgenerally not contribute to the tissue differentiation. But, thenoise generated due to above mentioned reason causes a grainyappearance on the image, hence image enhancement is required.For the intent of image denoising, Adaptive Multiscale ProductThresholding based on 2-D wavelet transform is used. In thismethod, contiguous wavelet sub bands are multiplied to improveedge structure while reducing noise. In multiscale products,boundaries can be successfully distinguished from noise. Adaptivethreshold is designed and forced on multiscale products as analternative of wavelet coefficients or recognize important features.For the edge enhancement. Canny Edge Detection Algorithm isused with scale multiplication technique.Simulation results shows that the planbetter suppress the Poisson noise among several noises i.e. salt &pepper, speckle noise and random noise. The Performance ofImage Intesification can be estimate by means of PSNR,MSE.
