| Abstract(in English) | It is well known that the standard JPEG algorithm causes visually disturbing blocking effects when high quantization parameter is used, in order to obtain a high compression ratio. In order to obtain a better compression performance for low bit-rate, we propose the JPEG with two-stage image size conversion in this paper. The proposed method is superior to the standard JPEG for low bit-rate, since, we can realize smaller quantization parameter. In the proposed method, we change JPEG to the JPEG with image size conversion depend on the bit-rate. We study how to change the compression methods. Moreover, we show that the proposed method is suitable for color image compression. |
