摘要: The Indexed color mode is used mainly in order to lower the number of colors and thus need for memory space. When RGB describe pixel values, there are totally 16,777,216 each image; however, an ordinary image usually does not so many colors. Generally, 256 enough common images; that is, it more than adequate select representative according content image. However, some images can be simple structure as (e.g. 128 colors, 64 colors) necessary. In this paper, we shall propose a new scheme incorporates both CIQBM Partial LBG. Our dynamically adjust needed other words, without damaging quality, our will use few possible present As result, reduce storage demand save transmission time over networks.
