ABSTRACT

In many imaging systems, detected images are subject to geometric distortion introduced by perspective irregularities in which the position of the camera with respect to the scene alters the apparent dimensions of the scene geometry. Applying an ane transformation to a uniformly distorted image can correct for a range of perspective distortions by transforming the measurements from the ideal coordinates to those actually used. Similarly, there are situations related to masking out certain areas of an image. is is done through logical operations that act on the image in a pixel-by-pixel manner and inhibit or manifest certain values depending on the operation. In this chapter, these two types of operations are explored in detail so that the reader can prepare for the advanced operations where these two operations will be used repeatedly to perform a higher level task.
