jpeg中DCT变换程序。为前向DCT的浮点运算，它要比整数运算更精确。该程序只适用于8×8的块变换。-jpeg DCT transformation procedure. For front to the DCT floating point calculation, it must be more precise than the integer operation. This procedure is only suitable for 8脳8 block transformati

H264中的整数DCT变换编码及量化代码,并附有原文的DCT编码、量化的说明文档。本源码从X264及JM中抽取后整理得来，并用原文档中的示例数据进行了测试，与原文档结果完全一样，是学习H.264不可多得的参考资源. -H264 in the integer DCT transform coding and quantization code, together with the original DCT coding, quantitative descr iption of the doc
