WebIn order to become suitable for digital processing, an image function f(x,y) must be digitized both spatially and in amplitude. Typically, a frame grabber or digitizer is used to sample and quantize the analogue video signal. Hence in order to create an image which is digital, we need to covert continuous data into digital form. There are two steps in which it is done: WebIn every imaging process, blur places a definite limit on the amount of detail (object smallness) that can be visualized. ... In effect, the MTF of the imaging system can cut out the higher frequency components associated with an object, and the image will be made up only of lower frequency components. Since low frequency components are ...
