中文摘要: 针对软件去噪算法难以满足实时图像处理的问题,采用基于FPGA的硬件滤波算法,该方案相对于软件算法具有高度的并行性和灵活的硬件可编程性.采用Matlab和QuartusII的联合测试平台,分析和优化了基于FPGA的维纳滤波算法的设计,同时通过实验结果比较了十字型与3×3型滤波窗口设计对滤波效果的影响,实验证明3×3窗口的滤波效果比十字窗口的滤波效果更好.
Abstract:Image filtering algorithms based on software do not often meet real-time image processing system.The solution to filtering algorithms based on FPGA not only provides an effective method to realize real-time parallel processing of large volume of data but also possesses the flexibility of hardware programability.Testing platform combined with Matlab and QuartusII is adopted to analyze and optimize wiener filtering algorithm based on FPGA.The filtering results of the designed methods of cross window and are compared with those of the 3×3 window,with the conclusion that the performance of the 3×3 window is better.
