程序代码说明 P0401：用Prewitt算子检测图像的边缘 P0402：用不同σ值的LoG算子检测图像的边缘 P0403：用Canny算子检测图像的边缘 P0404：图像的阈值分割 P0405：用水线阈值法分割图像 P0406：对矩阵进行四叉树分解 P0407：将图像分为文字和非文字的两个类别 P0408：形态学梯度检测二值图像的边缘 P0409：形态学实例——从PCB图像中删除所有电流线，仅保留芯片对象 ( Procedure code explanation P0401: Examines the picture with the Prewitt operator the edge P0402: Examines the picture with the different sigma value LoG operator the edge P0403: Examines the picture with the Canny operator the edge P0404: Picture threshold value division P0405: Divides the picture with the water line threshold value law P0406: Carries on to the matrix four forks the tree decomposition P0407: Divides into the writing and the non- writing two categories the picture P0408: The morphology gradient examines two values pictures the edge P0409: The morphology example 鈻♀枴deletes all electricity streamline from the PCB picture, only retains the chip object )

用实数编码求盲均衡,包含一些测试代码，效果还不错(Demand with real-coded blind equalization, including some test code, the results were good)

these codes implement out of band carrier de activation for OFDM. the number of subcarriers is flexible.

Small multiplication table.
