Abstract
The method for searching a video event includes: capturing a video; obtaining multiple pixels corresponding to the video; calculating a pixel difference value of each pixel by comparing frames at different timestamps in the video; dividing the video into multiple video segments, each video segment including a group of frames; determining a representative value for each pixel in each video segment according to the pixel difference value of each pixel; generating a metadata file which records the representative value for each pixel in each video segment; and searching an event in the video according to the metadata file.
