摘要
实时图像分割对于实时图像处理系统具有非常重要的意义。对于具有二次曲线边界的图像,为了确定其边界以进行实时分割,必然涉及到硬件电路上数据的开方等复杂计算,这对于一般情况下数据传输速率达到80MHz左右的实时图像处理系统来说无疑是个很大的挑战。为了完成图像分割,文章通过一种逐位比较的算法以确定图像边界,该算法的数学本质是利用二分法进行数值计算。而在具体实现方面,设计了基于FPGA的硬件电路,其中处理器内部结构采用数据通路和数据控制通路分离的方式,并通过VerilogHDL语言编程下载。最终实现了对具有二次曲线边界的图像的实时物理分割。
Real-time image segmentation has great significance of real-time image processing. To capture me boundary of an image with conic edges, extracting roots on circuit is affirmatively involved. For realtime image processor, which designed to handle pixel data transmitting in approximately 80 MHz, it is definitely a challenge. The bit after bit comparison arithmetic with the hypostasis of bisection method is applied to real-time image processing. The hardware, a circuit including FPGA, is designed primarily. And the processor＇s structure inside the FPGA is programmed in advance of separate structure of data flow and controller. The purpose of real-time physics image segmentation is finally completed.
