Performance comparison of contourlet and wavelet transform in denoising of ultrasound image
Pictures are simple way of representing information. At the time of applying operations like segmentation, feature extraction, feature analysis image should be noise free. The purpose of image de-noising process is to eliminate the without affecting actual quality of image. Introduction of noise is due to disgraceful securing, transmission and gathering and capacity and recovery forms. As noise gets introduced in image, there is degradation in visual quality of image. There are many types of noises present into image such as Speckle noise, Additive noise.
