Improved Median Filtering Algorithm and Its Hardware Implementation of FPGA

为了有效抑制数字图像在其获取和传输过程中受到的噪声污染,基于中值滤波,提出一种具有噪声检测模块的改进中值滤波算法,并在FPGA硬件平台上实现,改善了传统中值滤波会模糊图像的缺点。由实验结果分析可知,该算法不仅能有效抑制噪声,而且还能保存更多的图像细节,从而提高图像处理质量。

In order to effectively suppress the noise pollution in the process of image acquisition and transmission,this paper presents an improved median filtering algorithm with noise detection module based on the median filtering.And it is implemented successfully in the FPGA hardware platform.It has improved the shortcoming that the traditional median filter will blur the image.The experimental results show that the proposed algorithm can not only suppress the noise effectively,but also save more details of the image,so as to improve the quality of image processing.
