Embodiment Construction

[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0031] refer to figure 1 , a distributed video key frame extraction method based on Hadoop, including:

[0032] S1. Get the raw video to be processed.

[0033] The original video in this embodiment is stored in Hadoop Distributed File System (HDFS). HDFS is used to store large amounts of data on cheap clusters. It improves reliability through multiple copies, and provides fault tolerance and recovery mechanisms; large files are cut into small files during storage, and the idea of ​​​​divide and conquer is used to allow many serv...

Abstract

The invention discloses a distributed video key frame extraction method based on Hadoop, comprising: obtaining the original video to be processed; splitting the original video into independent image frames according to a preset sequence; detecting whether the image frame contains Including the first target, if the image frame contains the first target, it is marked as a target frame, otherwise it is marked as a normal frame; the target frame is divided into several target frame collections; the key frame of each target frame collection is obtained respectively ;Generate a key frame collection based on the key frames of all target frame collections. The invention extracts the key frame for the part containing the target in the video, and improves the efficiency of key frame extraction.

Description

technical field [0001] The invention belongs to the technical field of video processing, in particular to a distributed video key frame extraction method based on Hadoop. Background technique [0002] The amount of all-media public opinion data collected during public opinion supervision is increasing exponentially, especially for video data. If all pre-processing and post-processing are performed manually, it will not only consume a lot of time and energy, but also easily miss key target information. The emergence of key frame extraction technology has greatly improved this situation. Key frames are not affected by time, audio and video synchronization, etc., and can also provide multiple ways for browsing and navigation. However, in the process of actually applying the key frame extraction technology, the biggest difficulty is that the key frame extraction speed is too slow. Contents of the invention [0003] The purpose of the present invention is to overcome the defic...
