| 摘 要： | 为充分利用视频的时空联系去噪,提出了视频的刚体模型.刚体模型以线性关系组织视频的像素,结合了像素间的时域和空域关联,可以通过主色调区域划分和边缘句法匹配获得视频的刚体分解及其对应关系.基于刚体模型的插值去噪利用像素值的空域邻近性和时域稳定性联合判断插值像素的参考价值.对常用测试视频的去噪实验表明了刚体模型的正确性,基于刚体模型的插值去噪方法在视觉效果和峰值信噪比上都表现出色. |
| 关 键 词： | 视频处理 视频去噪 刚体模型 插值去噪 时空联合去噪 |

| Abstract: | A rigid model of video is proposed to denoise videos via temporal-spatial relations of video.The rigid model(RM) resolves videos into rigid block and organize the pixels with linear relations,combining the special and temporal relations.Rigid blocks and the correspondences is generated by color dividing and syntax matching of edges.In interpolation denoising based on RM the references is judged by pixels' neighborhood in space and stability in time domain.The validity of RM and Interpolation based on RM is ... |
