摘要
为了适应图像的存储和传输,需要对图像进行压缩以减少数据量。由此,许多压缩技术和标准应运而生,取得了相当优秀的成果。但对于彩色图像而言,其色彩模式和数据组合直接影响了压缩效率。根据彩色图像的数据结构将图像的色彩进行提取,并利用JPEG压缩标准分区域操作,从而实现JPEG压缩模式下的无色彩压缩。实验表明,该算法得到的压缩图像在与JPEG同等质量的条件下,数据量要远小于JPEG压缩的数据量,同时可实现不同压缩比的高质量压缩。
In order to adapt image storage and transmission, researchers need compress image to reduce image data. Therefore, many image compress techniques and standards have been introduced and made, and they have acquired very excellent production. For the color image, its mode of color and combination of data has a direct effect on the compressed effection. In the present paper, the researchers use JPEG compress standard and image data structure operating image by talking the color of the image according to the data structure of the colored image, so as to realize the colorless compress with JPEG compress mode. Experiments show that the compressed image data by this operator turn out to be less than that of JPEG compress mode in condition to coequality effect with JPEG. And at the meantime, a high quality compress can be realized by different compressive percentage.
