Abstract
A method for generating a video synopsis may include: segmenting a video file into a plurality of video fragments. The method may also include extracting moving object information from the video fragment based on a distributed computing method and determining a plurality of index files based on the moving object information. The method may further include combining the plurality of index files and generating a video synopsis based on the moving object information and the combined index file.
Claims18
A method for generating a video synopsis comprising:
- segmenting a video file into a plurality of video fragments;
- extracting moving object information from the plurality of video fragments based on a distributed computing method;
- determining a plurality of index files corresponding to the plurality of video fragments based on the moving object information;
- combining the plurality of index files;
- and
- generating a video synopsis by:
- arranging the moving object information based on the combined index file;
- generating video data of a plurality of frames based on the arranged moving object information;
- and
- encoding the video data into the video synopsis.
A method for generating a video synopsis comprising:
- segmenting a video file into a plurality of video fragments;
- extracting moving object information from the plurality of video fragments based on a distributed computing method;
- obtaining a first moving path sequence for a first section in a first video fragment based on the moving object information;
- obtaining a second moving path sequence for a second section in a second video fragment based on the moving object information;
- comparing the first moving path sequence and the second moving path sequence;
- determining a duplicate moving object of the first video fragment and the second video fragment
- removing the duplicate moving object from the first video fragment or the second video fragment;
- determining a plurality of index files corresponding to the plurality of video fragments based on the moving object information;
- combining the plurality of index files;
- and
- generating a video synopsis based on the moving object information and the combined index file.
A system comprising:
- memory storing instructions;
- and
- at least one processor that executes the instructions to perform operations comprising:
- segmenting a video file into a plurality of video fragments;
- extracting moving object information from the plurality of video fragments based on a distributed computing method;
- determining a plurality of index files corresponding to the plurality of video fragments based on the moving object information;
- combining the plurality of index files;
- and
- generating a video synopsis by:
- arranging the moving object information based on the combined index file;
- generating video data of a plurality of frames based on the arranged moving object information;
- and
- encoding the video data into the video synopsis.
