DCT变换在彩色图像有损RLE压缩中的应用研究

游程编码（RLE）压缩方法原理简单且易于实现，对于相邻数据相似性很大的数据进行压缩，压缩效果特别明显。在众多的压缩算法中，RLE压缩属于无损压缩，能够对原始数据进行完整的还原。将DCT和RLE相结合能够实现彩色图像的有损压缩，并且能够在可以接受的损失范围内，获取比较好的压缩比。

DCT Transform in the Image Damage RLE Compression on the Application

Run-length encoding （RLE） compression method is simple and easy to realize principle, similar to the data of the adjacent lot of data compression, compression effect particularly evident. Among the many compression algorithm, RLE compression is lossless compression to the original integrity of the data reduction. DCT and RLE will be combined to achieve the lossy compression of color images, and can be accepted within the framework of the loss of access relatively good compression ratio.
