Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0035] Computer Vision (Computer Vision, CV) is a science that studies how to make machines "see". Furthermore, it refers to the use of computer equipment such as cameras and computers instead of human eyes to identify, track and measure target objects in images, etc. , the image can be further processed to make the processed image more suitable for human observation or easier to transmit to other equipment for detection. The theory and technology related to computer vision research, trying to build an artificial intelligence system that can obtain information from images or multi-dimensional data. Computer vision technology can usually include image processing, image recognition, image semantic understanding, image retrieval, OC...

Abstract

The invention relates to the field of computer vision, provides a video cropping method and device, computer equipment and a computer readable storage medium, and aims to solve the problem that the video cropping efficiency is low or key parts in a video are easily cropped off in the prior art. The method comprises the following steps: obtaining a region of interest of an initial video frame in ato-be-cropped video; tracking the region of interest in each frame of video after the initial video frame in real time; cropping each frame of the to-be-cropped video by taking the edge of the regionof interest or the extended edge around the region of interest as a cutting boundary according to a real-time tracking result of the region of interest to obtain a cropped video; and outputting the cropped video. According to the technical scheme, on one hand, the efficiency is high, the cost is low, and on the other hand, important and key parts of the to-be-cropped video are reserved when the to-be-cropped video is clipped, so that the video cropping effect can meet the requirement of a user for the video.

Description

technical field [0001] The present application relates to the field of computer vision, and in particular to a video cropping method, device, computer equipment and computer-readable storage medium. Background technique [0002] In the field of video processing for product advertisements, a lot of high-quality pictures of a certain product are obtained through picture optimization, and then these pictures are made into videos by means of picture switching, and these pictures are displayed, or a video is shot for a certain product, and then By optimizing these original videos with a pre-defined template, a dynamic product advertisement (Dynamic Product Advertisement, DPA) can be obtained. [0003] Generally speaking, the specifications of the video PAD produced for a certain product are fixed and single. To make the video adaptable to different ad slot specification requirements, the specification of the video must be trimmed. At present, methods for clipping the video PAD ...
