基于小变换，以及边缘融合算法的图像边缘检测算法。包含了在多尺度下层层检测分解重构图像。-Based on the small change, as well as the edge of fusion algorithm of image edge detection algorithm. Included at every level of multi-scale decomposition of reconstructed image detection.

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]

数字图象处理算法的演示，包括：图象的DFT和逆DFT，图象的FFT和逆FFT，在图象中加入正弦噪声，图象的模板运算实现图象平滑和锐化等等。-digital image processing algorithms demo, including : Image DFT and inverse DFT, FFT image and inverse FFT, in the image by adding sinusoidal noise, the template image Operational Image sharpening and smoothing and so on.
