- 在数字信号处理领域用的较多的是DSP和FPGA。DSP的优势源于多数信号处理算法的乘-累加运算都是非常密集的。FPGA通过多极流水线架构也能够用来实现MAC单元,并且FPGA技术可以通过一个芯片上的多级MAC单元来提供更多的带宽,速度可以比数字信号处理芯片快,并且功耗较低。CORD IC算法完全由移位和加法操作完成,因此利用FPGA可以实现更高的运算速度。采用流水线结构在FPGA上实现基于CORD IC的对数变换,可以达到80MHz的处理速度。

histogram
- 灰度直方图是灰度级的函数,描述的是图像中具有该灰度级的像素的个数。它是多种空间域处理技术的基础。直方图操作能够有效用于图像增强;提供有用的图像统计资料,其在软件中易于计算,适用于商用硬件设备。直方图均衡化是通过对原图像进行某种变换,使原图像的灰度直方图修正为均匀分布的直方图的一种方法。图像灰度 直方图均衡化使得图像的灰度分布趋向均匀,图像所占有的像素灰度间距拉开,加大了图像反差,改善了视觉效果,达到增强目的。MATLAB是数字图像处理的常用工具,应用MATLAB的各种函数能够对数字图像进行各种处
