Problems solved by technology

In fact, both the artifacts and the current limitations of processing performance make such an approach (i.e., an on-site evaluation of all the information captured by many cameras) impractical

Embodiment Construction

[0039] In practical situations, a single operator may be responsible for monitoring several camera views simultaneously. Typically, in a store, surveillance cameras may cover entrances, checkout lanes and many locations within the store. If a suspicious individual is targeted, this will mean reduced awareness of other views, since the operator will have increased awareness of the targeted individual.

[0040] According to the present invention, when a target person is selected for tracking (ie, identified as an object to be tracked), the operator can make an effective selection. As a result, the operator's attention can be diverted elsewhere, and if one of the prohibited actions is in progress, the system will generate an alert signal whereby the operator can be notified to fully review the situation.

[0041] figure 1 The inventive method according to a first embodiment 100 of the inventive method is illustrated. The method 100 is initiated by a step 102 of detecting a tar...

Abstract

A method for generating an alert signal in a surveillance system is disclosed. The method comprises detecting a targeted individual in a video stream, selecting the targeted individual, and tracking the targeted individual, as first steps. Following these steps the method comprises classifying actions of the detected individual over a plurality of image frames in the video stream in response to the identification of the detected object as being a targeted person, and generating an alert signal if the classified action of the object is classified as a predefined alert-generating action.

Description

technical field [0001] The present invention relates to a method for tracking an object, and in particular to a method for generating an alarm in a video surveillance system. Background technique [0002] Within the fields of video surveillance and video analysis, motion recognition is an area of ​​development. The purpose of action recognition is to achieve automatic detection of actions (usually human actions) performed by objects in the monitored scene. An example might be that a perimeter sensor could generate an alert when an individual or object is entering a certain area, and motion recognition could generate an alert when the same individual assumes a hostile posture. Facilitate development with improved graphics processing technology, deep learning, and more for more advanced processing in less time. [0003] There are several known techniques for action recognition, and they can be divided into spatial and temporal techniques, where spatial techniques include, fo...
