Local rank transform: Properties and applications

In this paper we discuss about some interesting properties of local rank transform and also about some possible applications of this transform such as in edge extraction and image enhancement. An interesting convergence property on the iterative application of this transform on a signal has also been proved in this work.

Research highlights
► The work discusses about definition and properties of Local Rank Transform (LRT).
► It introduces the concept of-LRT and its uses in developing image processing algorithms.
► The work presents new algorithms of edge extraction and color image enhancement based on LRT.
