Depth sequence generation method of technology for converting plane video into stereo video

Abstract

The invention relates to a depth sequence generation method in a technique of converting a plane video to a stereo video, belonging to the technical field of a computer multimedia, in particular to the technique of converting the normal plane video to the stereo video. The method includes: based on an optical flow algorithm, a two-dimensional motion of a pixel of a frame in an original two-dimensional video sequence is picked up to obtain an image of a motion intensity of the frame; by utilizing a minimum discrimination information principle, the coloring information of the image of each frame in the original two-dimensional video sequence is mixed with the image of the motion intensity to obtain a distinguishing image of a motion color used for cutting a video image; the image is cut according to the luminance of the distinguishing image of the motion color; and a different depth value is given to each cut area to get a depth map of the image of each frame; the depth maps of the image of all frames constitute a depth sequence. The depth sequence generation method has the advantages that the space and time information of the video sequence are used jointly, and the judgment of the cutting and the depth are accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of computer multimedia, and in particular relates to a technology for converting common plane video into stereoscopic video. technical background [0002] Stereoscopic video, compared with the widely used flat video, can provide users with the depth information of the scene in the video, so that users can see the scene almost completely consistent with the real world through the video, resulting in a huge sense of reality and presence. Due to this huge advantage, stereoscopic video is being promoted and favored more and more all over the world and in many industries. For example, according to statistics in 2006, there are about 1,500 stereoscopic displays in 12 central cities in China, some of which are arranged in large shopping places and entertainment venues, playing pre-made advertisements or other promotional videos, giving people a strong impression. The visual impact attracts the audience's attention...

Problems solved by technology

[0017] The purpose of the present invention is to overcome the deficiencies of the prior art, and propose a method for generating depth sequences in the technology of transforming flat video into stereoscopic video, which can fully automatically implement each step of a video sequence without manual intervention. The acquisition of the depth map of the frame, so as to obtain the depth sequence of the original video sequence, can well realize the technology of converting flat video to stereoscopic video
