Embodiment Construction

[0049] The present invention proposes a video splicing method based on interpolation transition:

[0050] Step 1. Size consistency.

[0051] In the adjacent video clips, calculate the average distance value of the anchor node of each target object in the previous video (first video), and adjust the same target object in all images in the next video (tail video) based on the distance value size of. Resizes all objects of interest for all images in the next video.

[0052] Step 2. Find the position of the best splicing point.

[0053] Calculate the average position value of the anchor node of each target object in each frame image in the adjacent video clips, and use this position as the coordinate origin to recalculate the position of the non-anchor key node of the same target object in the image and the relationship between the relevant key nodes direction between.

[0054] In adjacent video clips, the stitching cost of the front and back images is calculated, including th...

Abstract

The invention provides a video splicing method and system based on interpolation transition. The method comprises the steps of unifying object sizes before and after a video, searching for the position of an optimal splicing point, unifying illumination brightness and object positions before and after the video, calculating the number of interpolation transition images and generating an interpolation transition image sequence. The technical scheme provided by the invention has the technical effects of smooth video transition, high speed and strong real-time performance.

Description

technical field [0001] The present invention relates to the technical field of computer vision and video processing, in particular, the present invention relates to a method and system for splicing video by using interpolation transition frames. Background technique [0002] Video stitching is an important part of video processing. In video communication, when the network bandwidth fluctuates, the variable bit rate video communication system can dynamically adjust the bit rate through scalable coding (such as adjusting resolution, frame rate or image quality), but for fixed bit rate video In the communication system, there will be obvious freeze phenomenon at the receiving end, which is specifically manifested as intermittent video. For the first case, the received image sequence can be uniformly interpolated to improve the frame rate of the video and the smoothness of playback. For the second case, it is necessary to supplement the paused image sequence fragments to mainta...
