Paper Abstract

Image restoration deals with functions of two variables. A function of two variables can be described by two variations, namely total variation and linear variation. Linear variation is a topological characteristic of a function of two variables. In this text we compare possible approaches to calculation of linear variation: the straightforward one, based on conventional algorithms for connected component labeling, and also we present a modification that exploits specificity of the problem to dramatically reduce complexity by reusing of intermediate results. Possibilities for further optimizations are also discussed.
