Image representation using Voronoi tessellation: adaptive and secure
نویسندگان
چکیده
An image is represented by the Voronoi tessellation generated from selected sampling points. Using a multiresolution approach, the density of the sampling points can be adaptive to image properties: smoother regions will have fewer sampling points than more detailed regions. The adaptation property results in better image quality than non-adaptive Voronoi representations, while preserving the property that only the holder of the seed of the pseudo-random number generator can reconstruct the original image.

Image representation using Voronoi tessellation
The major approaches to image representation [l] in terms of its constituent regions may be divided into two broad categories: (1) those which specify the borders of the regions and (2) those which describe their interiors. Most of the approaches and the more interesting ones, belong to the latter category. This may be attributed to the increased dimensionality of information (regions, rather t...

متن کاملTexture segmentation using Voronoi polygons
Texture segmentation is one of the early steps towards identifying surfaces and objects in an image. Textures considered here are de ned in terms of primitives called tokens. In this paper we have developed a texture segmentation algorithm based on the Voronoi tessellation. The algorithm rst builds the Voronoi tessellation of the tokens that make up the textured image. It then computes a featur...
