カラー画像の多階調型ブロック符号化

抄録

This parer describes a modified technique for Block Truncation Coding and its application to color images. The technique uses a 1-4 level adaptive quantizer based on the K-means clustering method over small block (local regions) of images. The technique is applied to color images by using a new two dimensional Plateau Coding which is a method for efficient coding the chromatic component. The paper presents the obtained good performance of the technique for typical color images.
