ABSTRACT
The computer operating on the television image in effect samples the data in object space into a finite number of spatial (2-D) data points that are called pixels. Each pixel is assigned an address in the computer and a quantized value that can vary from 0 to 63 in some machine vision systems or 0 to 255 in others. The actual number of sampled data points is going to be dictated by the camera properties, the analog to digital converter sampling rate, and the memory format of the picture buffer or frame buffer as it is called.
