摘要

在本研究中，我们研究了几种非线性滤波器在图像信号降噪方面的性能。我们发现全变分(TV)正则化滤波器在有效降噪和保持图像质量方面表现出最好的性能。我们分析了电视正则化滤波器的行为，并阐明了如何在不损失边缘清晰度或图像细微性的情况下有效地降低噪声。

Nonlinear filters for noise reduction in image signals

In this study, we investigate the performance of several nonlinear filters for noise reduction in image signals. We find that the total variation (TV) regularization filter exhibits the best performance for effective noise reduction and picture quality preservation. We analyze the behavior of the TV regularization filter and elucidate how noise is reduced effectively without losing edge sharpness or picture minuteness.
