| 摘 要： | 图像DCT变换是图像压缩的一项重要技术,如何准确、快速地进行图像压缩一直是国内外研究的热点.现研究了两种二维离散余弦变换(DCT)的方法.在DCT算法结构上利用了变换的可分离性和行列的可分解性,并采用行列分解的方法将二维DCT转换为2个串行的一维DCT实现.

| Abstract: | The image DCT transform technique is an important technique in the field of image compression.How to compress the image accurately and fast has been a research focus both at home and abroad all the time.In this paper,two methods which are used to achieve two-dimensional discrete cosine transform(DCT) have been studied.Two-dimensional DCT is converted to two serial one-dimensional DCT by using separability of transform and resolvability of row-column. |
