2D video three-dimensional method based on sample learning and depth image transmission

The invention discloses a 2D video three-dimensional method based on sample learning and depth image transmission. The problem that in an existing 2D video three-dimensional process, computation complexity is high, and applicability is poor is mainly solved. The method comprises the steps that (1) two frames of 2D video images are input; (2) the best depth values of pixel positions of the first frame of video image are obtained through the method based on sample learning; (3) the best depth values are subjected to postprocessing; (4) the depth values of pixel positions of the input second frame of video image are obtained through a depth transmission technology; and (5) through a drawing technology based on depth images, input video images and the obtained depth values of the pixel positions are combined, and left-right-format 3D video is formed. According to the method, computation complexity is low, high-quality depth images which are obvious in moving foreground, clear in edge and natural in structure can
