摘要
一些简单的图像处理算法如边缘检测,平滑滤波和线性插值等都是针对输入图像若干象素临域进行计算。在FPGA中实现此类算法需要首先构造输入图像临域,根据临域大小预取若干行输入图像象素数据存入片内存储器中。本文讨论独立于计算过程的两级图像输入缓存的设计机制,该机制可用于任意的需要按行序构造输入图像临域的图像处理算法之中。
Some primary Image Processing algorithms such as edge detective,smooth filter and linearity interpolation are all in allusion to rectangular region of input image.To implement these kinds of algorithms with FPGA needs to put several lines of pixels into stor age inside FPGA to construct expectative image region.An algorithm-independent 2 level image input buffer design mechanism is in troduced,it can be used for all image processing algorithms which need horizontal input image region.
