dct.pdf中介绍的公式非常经典，但其中的一段源程序有一些错误，但在C文件dctmatrix.c有了修正。 dctmatrix.c给出了如何定标DCT系数。 dctmatrix.c中，FIX_DCTMTX_2[Rows][Columns]采用Q11定标,FIX_DCTMTX采用Q15定标。 DCTMTX_2[Rows][Columns]*2=DCTMTX[Rows][Columns]-dct.pdf formula described in a very classic, but a section of source code has some mistakes, but in C has been amended dctmatrix.c document. How dctmatrix.c given DCT coefficient calibration. dctmatrix.c in, FIX_DCTMTX_2 [Rows] [Columns] using Q11 calibration, FIX_DCTMTX calibration using Q15. DCTMTX_2 [Rows] [Columns]* 2 = DCTMTX [Rows] [Columns]
