摘要
为了满足图像实时处理时对速度的要求,以及适应能够同时抑制高斯噪声和脉冲噪声的需要,提出了一种简单有效的滤波方法-混合滤波。MATLAB上的算法仿真表明:通过将中值滤波器与均值滤波器级联,可以有效的滤除视频图像中的混合噪声(脉冲噪声和高斯噪声)。采用VerilogHDL对电路进行设计,并在Xilinx公司的Spartan-IIE系列芯片上实现了混合滤波器。此滤波器算法简单,便于硬件实现,可以应用于实时图像处理中。
A simple and efficient filter method, called mixed filter, is presented to fulfil the speed requirement of real-time image process and to restrain Gauss noise and the pulse noise. The mixed-filter is the concatenation of median filter and average filter, the result from MATLAB for the algorithm of the mixed-filter indicated that the mixed-filter can filter Gauss noise and the pulse noise. The filter is described with Verilog, realized on Spartan-liE series chip of Xilinx CO, The filter algorithm has advantage, simple and easy to be implemented in hardware. It can be used in real-time image process.
