In this chapter as well as in the following two, elementary image operators and their parallel implementation are introduced. We differentiate between point operators, local and global image operators. Point operators are the simplest image operators in regard to complexity and computing time. They require no data from other pixels to process an input pixel into an output pixel, but simply calculate a single-parameter function with the input pixel as the parameter.
