Abstract: De-noising of images is an important task in image processing and analysis, and it plays a significant role in modern applications in different fields, including medical imaging and pre-processing for computer vision. This paper analysis various medical image using different wavelet transform. Particularly the discrete wavelet transform (DWT) is best suited for De-noising of medical image. To apply two dimensional DWT is applied to the image and the four different sub filters section are obtained. Each section has some threshold value based on the noise effect. The inverse DWT (IDWT) is applied and de-noise effect estimated. To apply various soft threshold techniques like, Visu Shrink, Sureshrink, Bayes Shrink, etc., are applied and results rare compared with state of art techniques. The physical parameters like, RMSE, MSE, PSNR, SNR etc.are compared.
