Embodiment Construction

[0067] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0068] A kind of 3D 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:

[0069] ① The original 3D video sequence to be processed consists of a color video sequence and a depth video sequence. Assuming that the total number of frames of the color image contained in the color video sequence and the total number of frames of the depth image contained in the depth video sequence are both T, the color The color image at time t in the video sequence is denoted as {I t (x,y)}, record the depth image at time t in the depth video sequence as {D t (x,y)}, where T>1, such as T=10, 1≤t≤T, 1≤x≤W, 1≤y≤H, W represents the color image and depth video sequence in the color video sequence The width of the depth image in, H represents the heigh...

Abstract

The invention discloses a three-dimensional video repositioning method. The three-dimensional video repositioning method comprises the step of firstly extracting an image saliency map, a gradient energy diagram and a motion saliency map of each frame of a color image in a color video sequence respectively, mixing with depth information of a scene to obtain a visual attention map of each frame of the color image in the color video sequence, and calculating an intra-frame consistency energy diagram and an inter-frame consistency energy diagram of each frame of the color image in the color video sequence; finding out all the vertical gaps of each frame of the color image in the color video sequence by adopting a dynamic planning method; and then removing pixels falling in all the vertical gaps of each frame of the color image in the color video sequence and pixels falling in the same vertical gaps of each frame of a depth image in a depth video sequence to obtain a repositioned color video sequence and a repositioned depth video sequence. The three-dimensional video repositioning method has the advantages that the image deformation of the obtained repositioned three-dimensional video can be reduced, time domain jitter of the obtained repositioned three-dimensional video can be avoided, outstanding content of the obtained repositioned three-dimensional video can be highlighted, and accordingly relatively high visual comfort is kept.

Description

technical field [0001] The invention relates to an image signal processing method, in particular to a three-dimensional video relocation method. Background technique [0002] With the rapid development and upgrading of video display devices (such as smart phones, tablet computers, TVs, etc.), display terminal devices with different resolutions and screen aspect ratios are flooding people's work and life. When the resolution of the image or video to be displayed does not match the resolution of the screen, how to change the resolution of the image or video content to adapt to display devices of different sizes without changing the viewing experience of the user as much as possible? It's a retargeting problem. Current solutions to this problem are: uniform scaling, cropping, and letterboxing. However, these traditional methods usually cannot achieve a good user experience effect, cannot fully utilize the size advantage of the display device, and degrade the user experience. ...
