java 实现的边缘检测算法，有Roberts算子、Prewitt算子、Laplacian算子、Sobel算子，有界面，直接运行org.zfz.app.PhotoApp，-java implementation of edge detection algorithms, Roberts operator, Prewitt operator, Laplacian operator, Sobel operator, interface, directly run org.zfz.app.PhotoA

用java使用了Sobel算子以及Laplace算子实现的图像边缘提取，时钟时间识别-With java using Sobel operator and the Laplace operator to achieve image edge detection, recognition time clock
