| 摘 要： | 非线性滤波是一种有效的噪声抑制技术，已得到了广泛的应用。本文针对中值滤波算法排序量多、速度慢的缺点，采用基于TMS320C6000系列DSP的C程序优化方法对中值滤波代码进行优化。与优化前的代码相比，优化后的代码的运行时间减短，代码的执行性能提高，可以满足实时图像处理的要求。

| Abstract: | Nonlinear filtering is an effective noise restraining technology and has
been widely used. In order to solve the problem that the speed of
classical median filter was slow because of a lot of sorting, in this paper,
the method of the C code optimization based on the TMS320C6000 Series
DSP is used to optimize the code of median filter. Compares with the
original code, the optimized code reduces the running time, enhancing
the performance of code execution. In addition, it will meet the requirement
of real-time image processing. |
