Embodiment Construction

[0039] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0040] First, the surveillance video quick preview system of the present invention is introduced.

[0041] refer to figure 1 , The surveillance video quick preview system of the present invention includes: a dynamic frame extraction module, a dynamic frame filter module, a dynamic frame playback module, a dynamic frame retrieval module, and a dynamic frame jump module. Wherein, the dynamic frame extraction module is used for extracting the dynamic frame image that contains moving target from video recording; The dynamic frame filter module is used for filtering out the dynamic frame that repeats in the dynamic frame image that the dynamic frame extraction module extracts, and retains Filter out the dynamic frames that contain less and repeated moving targets in the dynamic frames, the dynamic frame extraction module extracts, and the dyn...

Abstract

The invention discloses a fast previewing system of a surveillance video. The fast previewing system comprises a dynamic frame extracting module for extracting a dynamic frame image containing a moving target from the surveillance videos, a dynamic frame filter module for filtering repeated dynamic frames, a dynamic frame play module for playing the filtered dynamic frame images, a dynamic frame searching module for searching dynamic frame images in a gallery, a dynamic frame jump module for jumping the dynamic frame images in the galley to the original video and starting playing the original video on a dynamic frame appearing part, and a dynamic frame storage module for storing the filtered dynamic frame images into a database. The fast previewing system disclosed by the invention has the beneficial effect that the dynamic frame image containing the moving target can be quickly previewed in the video before a user replays the video, and the video can be replayed from the part when the interested moving target is seen; static frames can be filtered and attention is concentrated on a significant moving target, so that the video viewing efficiency is improved.

Description

technical field [0001] The invention relates to a surveillance video preview system and a preview method, in particular to a surveillance video quick preview system and a quick preview method, belonging to the technical field of multimedia processing. Background technique [0002] It takes a lot of manpower to find clues to solve crimes in massive surveillance videos, which has always been a difficult problem in video surveillance applications. There are often large segments of still images in surveillance videos, which contain very little effective information. What we need to browse carefully is a dynamic picture containing moving objects (such as people, vehicles, etc.). [0003] The conventional processing method is to fast forward / rewind, or drag the time bar to choose to play. However, these manual methods for searching for moving objects are less efficient because they do not know where the moving objects appear. [0004] Another approach is video enrichment (or vi...
