Sobel边缘检测的FPGA实现

Implementation of Sobel Edge Detection Based on FPGA

为了采用FPGA来实时实现Sobel边缘检测,设计者往往自己编写代码。在此介绍基于QuartusⅡ提供的参数可设置宏功能模块,实现Sobel边缘检测的新方案。该方案获得了比用户编写的代码更优的综合和实现结果,节省了宝贵的设计时间,并且获得了很好的边缘检测效果。

To realize real- time Sobel- edge detection using FPGA,designers often encode their own logic. A new design scheme of Sobel - edge detection based on the Quartus Ⅱ - provided parameterizable Megafunctions is introduced. The scheme gets more efficient logic synthesis and device implementation than coding users＇ own logic,saves valuable design time and obtains very good result.
