| 摘 要： | 针对实时图像处理的要求,使用FPGA对图像数据流进行在线Prewitt边缘检测。针对传统算法需要人工给定阈值和产生的边缘较宽的不足,用基于FPGA的自适应阈值算法和非极大值抑制方法对边缘检测的结果进行细化处理,提高了边缘检测的精度。

| Abstract: | For real-time image processing requirements,this paper presents an FPGA-based design of online Prewitt edge detection to process the image data streams.For the shortage that the traditional algorithm needs a given threshold manually and produces wide edge,a method of adaptive threshold and non-maximum supression based on FPGA is used.The method thinning the results of edge detection,improve the accuracy of edge detection. |
