Abstract |
|
Today, the transmission of information takes place mainly through digital images and videos, but the image obtained after transmission is often corrupted with noise. The received image needs processing before it can be used in applications. Image denoising involves the manipulation of the image data to produce a visually improved quality image. In this paper, a brief study on different noise models is presented. They include Gaussian noise, salt and pepper noise, shot noise, speckle noise and thermal noise. This work reviews the existing denoising algorithms, such as filtering approach and wavelet based approach and performs their comparative study. Selection of the denoising algorithm is application dependent. |
