Problems solved by technology

The traditional method of video scaling is by cropping or scaling by a fixed ratio, but doing so may reduce the content of the video or cause significant object deformation
[0003] For stereoscopic video, if the same video relocation method is directly used for left-viewpoint video and right-viewpoint video, that is, the left-viewpoint video and right-viewpoint video in stereoscopic video are processed separately, it will cause wrong depth information; at the same time, when stereoscopic When the video has fast depth motion, the traditional depth preservation will make the repositioned stereoscopic video still have uncomfortable depth motion, which will cause visual discomfort and affect the viewing experience

Embodiment Construction

[0066] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0067] A kind of stereoscopic video repositioning method that the present invention proposes, its overall realization block diagram is as follows figure 1 As shown, it includes the following steps:

[0068] Step 1: define the current left-viewpoint video image and the current right-viewpoint video image correspondingly to the t-th frame left-viewpoint video image and the t-frame right-viewpoint video image to be processed in the original stereoscopic video sequence to be processed; wherein, t is Positive integer, the initial value of t is 1, 1≤t≤T-1, T represents the total number of frames and the included width of left-viewpoint video images with a width of W and a height of H contained in the original stereoscopic video sequence to be processed W is the total number of frames of right-view video images with a height of H, T is a positive in...

Abstract

The invention discloses a stereoscopic video repositioning method. Depth motion energy, shape maintaining energy, time domain consistent energy, space consistent energy and parallax maintaining energyof target quadrilateral grids corresponding to all quadrilateral grids in a left viewpoint video image and a right viewpoint video image at each moment of a stereoscopic video are extracted, and theoptimal similarity transformation matrix is obtained through optimization, so that important significant semantic information can be well reserved for the obtained repositioned stereoscopic video, thetime domain consistency can be well kept, the size of the stereoscopic video can be effectively adjusted, and the visual comfort can be kept.

Description

technical field [0001] The invention relates to an image signal processing method, in particular to a stereoscopic video repositioning method. Background technique [0002] With the rapid development of stereoscopic display technology, various stereoscopic display terminals with different stereoscopic display functions have also appeared widely. However, due to the wide variety of stereoscopic display When a certain stereoscopic video is displayed on different stereoscopic display terminals, the size of the stereoscopic video must be adjusted first to achieve a stereoscopic display effect. The traditional method of video scaling is by cropping or scaling by a fixed ratio, but doing so may reduce the content in the video or cause significant object deformation. [0003] For stereoscopic video, if the same video relocation method is directly used for left-viewpoint video and right-viewpoint video, that is, the left-viewpoint video and right-viewpoint video in stereoscopic vid...
