Abstract

Three-dimensional weighted median filters for noise reduction in gray-level image sequences are presented. The filters are designed to retain completely nonmoving regions in image sequences. In moving regions, 3-D filter structures adapt automatically to changes in image sequence content and perform a filtering operation in moving regions. Noise attenuation capability of the filters is studied. The performance of the filters in terms of detail preservation and noise reduction is examined using real image sequences.<>

图像序列滤波中保留非移动区域的中值滤波器

提出了用于灰度图像序列降噪的三维加权中值滤波器。滤波器被设计成保留图像序列中完全不移动的区域。在移动区域中，三维滤波器结构自动适应图像序列内容的变化，并在移动区域中执行滤波操作。研究了滤波器的噪声衰减能力。使用真实图像序列检验了滤波器在细节保留和降噪方面的性能。
