During acquisition of images in image analysis various factors occurs which causes degradation of images. To restore the information present in the images certain image restoration techniques are available in research areas. The method of restoring the degraded images is known as image restoration process. The visibility of the images is improved by the use of restoration techniques which is achieved by the removal of added noise and degraded function from the original image. Inverse convolution of the degraded image with that of the restoration method is done to remove the noise and blurs existing in the original image. Various methods are available today for the restoration of the images like wiener filters, inverse filters, and constraint least square filter and blind restoration method. The methods of restoration are either linear or non linear depending on the type of images and the noise present in the original images.
