Provided are a three-dimensional video filtering method and device, the three-dimensional video filtering method comprising: projecting the pixels in the plane of an image into three-dimensional space; according to the coordinate values of the pixels to be filtered and the reference pixels in the three-dimensional space, calculating the spatial proximity of the pixels to be filtered and the reference pixels in the three-dimensional space; according to the texture pixel values of the pixels to be filtered and the reference pixels, calculating texture pixel value similarity of the pixels to be filtered and the reference pixels; according to the texture pixel values of the pixels to be filtered, the reference pixels, and the pixels in the same position in the previous frame of the image, calculating motion characteristics consistency of the pixels to be filtered and the reference pixels; calculating the weight of the pixels to be filtered; determining filtering weight according to the proximity, texture pixel value similarity and motion characteristics consistency, and conducting weighted averaging on the pixel values of the reference pixels to obtain a filtering result of the pixels to be filtered, thus improving three-dimensional video filtering accuracy. |
