ijariie.com2.1 Image Acquisition An image can be defined as a two-dimensional function, f (u, v), where u and v are plane coordinates, and the amplitude of f at any pair of coordinates (u, v) is called the intensity or gray level of the image at that point[3]. We can call an image as digital image, when u, v and the amplitude values of f are all finite ...

The images acquired by these cameras may appear grainier due to lower signal to noise ratio. • But they address one particular application, i.e. deblurring in a very principled way. • Spread spectrum filters may not be available in many different
