Optimal palette create with the specified number of colors using octree quantization

Abstract EN

In the current research work, improved and fast method to get a good approximation of the most important 256 colors of a RGB-Picture was introduced.

In this paper, we propose a spatially-adaptive optimum octree quantization method for robust color printing.

The goal of spatially-adaptive octree quantization is to use quantization well-suited for smooth areas, and to use octree quantization method better suited for edges.

It may be useful for digital image compression, graphics- and game programmers.

Also, this includes reduction of the overall number of colors, quantization or patterning the reduced number of colors, generating bitmap images, and even handling Boolean (on / off) transparency.

The results show the suggested adaptive octree data-structure is useful for color-quantization.
