Abstract

Representation of the digital image by a triangulation does not bring a high compression but enables geometric transformations and is very simple. In this paper we will show that it is also possible to choose the triangulation vertices randomly, then their [x,y] position does not need to be stored as it can be easily reconstructed during decoding. We show how such a choice behaves in comparison and in combination with the vertices selected from the edges of the digital image.
