Embodiment Construction

[0061] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0062] Such as figure 1 Shown, the inventive method comprises the following steps:

[0063] 1) For each frame image of the video to be repaired, the image of its adjacent frame is projected onto the image of the current frame using the depth information and camera parameters, and the pixel point is selected from the hole area of ​​the video to be repaired according to the projection result to establish a repairable pixel point area Ω t As a part of the hole area, and then perform time-domain consistent depth and color patching on the part of the hole area in the video;

[0064] 2) For the remaining hole area of ​​the video to be repaired, select the image frame with the largest remaining hole area, use the image interpolation method and flood filling method to complement the color and depth of the remaining hole area in the frame im...

Abstract

The invention discloses a time-domain-consistent cavity region repairing method for a static scene video shot in motion. The method comprises the following steps: projecting the image utilization depth information and camera parameter of an adjacent frame onto an image of a current frame, selecting pixel points from the cavity region of a video to be repaired according to a projection result to establish a repairable pixel point region serving as a pair of the cavity region, and performing time-domain-consistent depth and color repairing on the part of cavity region in the video; and complementing the color and depth of a remaining cavity region in a frame image by adopting an image interpolation method and a flood-fill method, projecting the frame image onto an adjacent frame image by using the depth information of the frame image, and repairing the color and depth of the remaining cavity region in the adjacent frame by using the color and depth of the projected image. Through adoption of the method, time-domain-consistent video cavity repairing can be realized, and the consistence and jumping freeness of video repairing are ensured; and moreover, full-automatic video repairing can be realized, the processing efficiency is high, and manual interaction assistance is not needed.

Description

technical field [0001] The invention relates to a video patching method in the technical field of video editing, in particular to a patching method for time-domain consistent hole regions of static scene videos captured in motion. Background technique [0002] With the development of digital image processing technology, more and more fields need to use video repair technology, and the so-called video repair is the process of filling the defect area in the video, the purpose is to fill the defect video completely, so that the observer cannot perceive it. This video used to be broken. Therefore, video repair technology has become a current research hotspot, and it has been widely used in cultural relics protection and video error concealment. At the same time, this technology can also be applied in the process of 2D to 3D conversion. [0003] There are many video inpainting techniques, such as the early image interpolation method (inpainting), which generally can only deal wi...
