摘要： A method for denoising images by block-matching three-dimensional (BM3D) method is disclosed in the present invention. Embodiments of the present invention are used to improve the quality of captured images. Instead of using the same noise variance to denoise all patches of an image, each patch is processed based on a particular assessed noise variance. The assessed noise variance of one reference patch is determined based on noise variance associated with the patch set or based on content characteristics associated with the patch set. The patch set is obtained by block-matching to find similar patches of the reference patch. Noise reduction in frequency domain is applied to the patch set according to the assessed noise variance of the reference patch. The determining of the assessed noise variance can be performed in spatial domain or in frequency domain.
摘要翻译：在本发明中公开了一种通过块匹配三维（BM3D）方法对图像进行去噪的方法。本发明的实施例用于提高拍摄图像的质量。代替使用相同的噪声方差去除图像的所有斑块，每个贴片将根据特定的评估噪声方差进行处理。基于与补丁集合相关联的噪声方差或基于与补丁集相关联的内容特征来确定一个参考补丁的估计噪声方差。通过块匹配获得补丁集，以查找参考补丁的相似补丁。根据评估的参考补丁的噪声方差，将频域的降噪应用于补丁集。评估噪声方差的确定可以在空间域或频域中进行。
