摘要

本文提出了一种内容感知的数字电视降噪方法，该方法可以保留图像的纹理和边缘。在该方法中，首先通过时间递归NR滤波器降低噪声，然后通过空间NR滤波器进一步抑制噪声。为了保持图像的纹理，在空间滤波中采用了在噪声图像中准确表示边缘的显著性映射。实验结果表明，与传统方法相比，该方法具有更好的NR性能。

A saliency based noise reduction method for Digital TV

In this paper, we propose a content-aware noise reduction (NR) method for the Digital TV, which preserves image textures and edges. In the proposed method, noise is first reduced by a temporal recursive NR filter and then further suppressed by a spatial NR filter. To preserve the image texture, the saliency map which accurately represents edges in a noisy image is employed in the spatial filter. Experimental results show that the proposed method exhibits the better NR performance as compared with conventional methods.
