49502 针对合成孔径雷达(synthetic aperture radar，SAR)图像不同内容间的统计特性差距较大以及采用非局部降斑方法处理SAR图像时会产生图像细节丢失及伪影等现象，提出了一种基于非局部分类处理的SAR图像降斑方法。 For synthetic aperture radar (synthetic aperture radar, SAR) image statistical characteristics of the gap between the different content is bigger and the nonlocal drop spot method processing SAR image will produce the phenomenon, such as loss of image details and artifacts is proposed based on a nonlocal classification processing of SAR image spot method.
49503 首先对相似块方差系数的均值采用阈值比较的方法将图像分为同质区和异质区， First on the similar piece variance coefficient of the mean image adopt the method of threshold value is divided into homogeneous and heterogeneous area,
49504 在寻找目标块对应的相似块时，根据图像块中心像素点所属的类别选择合适的参数进行块匹配， when looking for a target block corresponding to the similar block, according to the category of the image block center pixel belongs to choose the appropriate parameter block matching,
49505 并在获得相似块后分别使用加权平均的方法处理同质区目标块和3D变换域硬阈值收缩方法处理异质区目标块。 and after getting similar piece respectively using weighted average method of homogeneous area target block and 3 d transform domain hard threshold shrinkage method to deal with heterogeneous area target block.
49506 该方法不仅能在块匹配过程中选择不同的块尺寸和搜索范围以提高块匹配的精度，而且使用不同方法处理同质区和异质区时能够在图像降斑与细节保持的权衡中达到更好的平衡。 This method not only can choose a different block size in the process of block matching and search scope in order to improve the accuracy of block matching and using different methods dealing with homogeneous area and heterogeneous areas in the image spot on details to keep balance to achieve a better balance.
