一种比较好用的边缘检测方法CORNER Find corners in tensity image. ％ CORNER works by the following step: ％ 1. Apply the Canny edge detector to the gray level image and obtain a ％ binary edge-map. ％ 2. Extract the edge contours from the edge-map, fill the gaps in the ％ contours. ％ 3. Compute curvature at a low scale for each contour to retain all ％ true corners. ％ 4. All of the curvature local maxima are considered as corner ％ candidates, then rounded corners and false corners due to boundary ％ noise and details were eliminated. ％ 5. End points of line mode curve were added as corner, if they are not ％ close to the above detected corners.

这段代码的作用是计算 ENET（以太网）模块时钟频率与 MDC（管理数据时钟）的最大频率的两倍之商再加一的结果。这个结果在以太网驱动程序中用于配置 PHY（物理层）寄存器，以确保 MDC时钟频率不会超过 PHY所能接受的最大值。具体而言，ENET_ROUNDED_UP_DIV() 是一个将除法结果向上舍入到最接近的整数的宏定义，其中 moduleClk 是ENET模块的时钟频率，而 FEATURE_ENET_MDC_MAX_FREQUENCY 是MDC的最大频率。
