摘要: Color quantization is a useful method for obtaining high-quality compressed images storage and subsequent distribution via the World Wide Web. The first step of most color techniques to create histogram colors in truecolor image. dramatic differences time space efficiency various data structures used represent image histograms are visually explored 3D. Spatial subdivisions use buckets store portion RGB cube. Linked lists typical structure buckets; we propose using red-black trees treaps. Our visualizations highlight clustering property spatial subdivision methods.
