本文探讨图象数据压缩的自适应DCT方法,针对给定细节较少的输入图象的特点,给出一种自适应DCT分区编码压缩处理方案。计算机仿真试验结果表明,此方案使数据压缩的效果和输出图象的主、客观质量得到了较大的改善。
In this paper, the adaptive DCT method for image data compression is discussed. For a given input image with less detail, an adaptive DCT partition coding compression scheme is proposed. Computer simulation results show that this scheme makes the data compression effect and the output image of the main and objective quality has been greatly improved.
