Impulse noise detection

By means of residual impulse noise detection, the window size of median filter was chosen adaptively to remove the high density impulse noise while preserving the details of the image.

通过对剩余脉冲的检测，自适应地改变滤波器窗口尺寸，从而有效地滤除密度较大的脉冲干扰，同时较好地保留图像的细节。

The technology of impulse detection is the key technology of image filter of impulse noise.

脉冲检测技术是脉冲噪声图像滤波的关键技术。

The optimization algorithm proposed can improve the performance of impulse detection algorithm; furthermore, heighten the overall performance of the OFDM receiver in impulsive noise environment.

本消隐非线性阈值的优化算法可以改进脉冲噪声检测算法的性能，进而大大改善OFDM系统在中压配电线脉冲噪声环境中的总体性能。
