Hough变换:对于边缘检测结果,使用Hough变换将直线参数表示转换到参数空间。对于检测水平形状的平板,可以使用标准Hough变换或改进的Hough变换(如Probabilistic Hough Transform)。 直线检测与过滤:在参数空间中对累加结果进行阈值设定,选取符合条件的直线参数,进而在原始图像中绘制检测到的直线。
Circle Hough Transform (CHT) has found applications in biometrics, robotics, and image analysis. In this work, the focus is the development of a Field Programmable Gate Array (FPGA) based accelerator that performs a series of procedures and results in circle detection. The design is performed ...
