Problems solved by technology

In the process of recognizing and detecting text in the video, too many frames are usually selected as key frames in order not to miss key frames, resulting in redundant key frames, which in turn leads to low confidence in the detection results and affects subsequent recognition precision

Abstract

The embodiment of the invention discloses a key frame deduplication method and device and electronic equipment. A specific embodiment of the method comprises the steps of obtaining a key frame set ofa video and a text area in each key frame in the key frame set; extracting feature points of the character area in each key frame; extracting similar key frames from the key frame set by utilizing thefeature points of the character area, and generating a key frame subset; and carrying out deduplication on the key frames in the key frame subset. According to the embodiment, the redundant key frames in the video are removed.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of computer technology, and in particular to a key frame deduplication method, device and electronic equipment. Background technique [0002] At present, with the comprehensive development of informatization construction, character recognition technology has entered the mature stage of industry application development. In the process of recognizing and detecting text in the video, too many frames are usually selected as key frames in order not to miss key frames, resulting in redundant key frames, which in turn leads to low confidence in the detection results and affects subsequent recognition precision. Therefore, how to deduplicate redundant key frames in video text detection is an urgent problem to be solved. Contents of the invention [0003] This Disclosure section is provided to introduce a simplified form of concepts that are described in detail that follow in the Detailed Description...
