| Abstract(in English) | Compressing texture features of natural images by conventional JPEG method requires many bits to preserve their feature details. Therefore, the highly compressed JPEG image does not have detailed texture. We define this degraded image without texture features as structure image, and also defined the difference between the input image and the structure image as texture image. In general, one can find the tight relationship between the edges of the structure image and the boundary of texture patterns in the texture image. Moreover, the texture image can be drastically compressed by focusing on the fact that the texture images contains a lot of repetitive features. From these observations, we proposed a novel image coding by using noiselet transform for representing the texture image, and making compaction image that has almost of all repetitive texture patterns. Then, the encoder sends the input image and compaction image compressed by JPEG method, and the noiselet coefficient. At the decoder side, we proposed reconstruction method for the compaction texture image from these information. |
