中文摘要：

介绍了一种用于数字电视系统中的视频噪声检测的优化算法，该算法采用了基于时域和空间域相结合的噪声检测方法，基于纹理分析器和同质分析器的运算，在平坦的或者运动的纹理较多的区域都能给出一个较为精确可靠的噪声估计结果。为数字电视图像后处理模块中尤其是数字降噪模块，提供及时准确的参考依据。

英文摘要：

An optimum design of noise meter in digital video processing of TV system is proposed. It adopts the combination detection method from both of temporal and spatial domains, and bases on the calculation of homogeneity analyzer and textual analyzer to estimate the noise level. The simulation result proves that the estimation result is accurate and reliable for both fiat and moving textual areas, and also get good applications for noise reduction IP in TV video processing.
