Design Approach of Colour Image Denoising Using Adaptive Wavelet

In modern age, visual information transmitted in the form of digital images is becoming a major method of communication, but the image obtained after transmission is often corrupted with noise. For obtaining the high quality image from original noisy image data manipulation is required. In this paper noise is remove by wavelet based approach & it is proved that wavelet based approach is best when the image is corrupted by Gaussian noise, salt and pepper noise, speckle noise and Brownian noise. Quantitative measures of comparison are provided by the signal to noise ratio of the image. In this paper colour image is denoise by using wavelet based approach & also improve the peak signal to noise ratio of the colour image.
