Abstract

The invention provides a method for communicating region in a scan unite image and a device thereof. The method includes steps as follows: firstly, scanning present line of the image for obtaining a communication segment of the present line; secondly, taking out a communication segment as the present segment for processing communication analysis; thirdly, judging upper line whether having a communication segment communicated with the present segment, if yes, executing fifth step, if no, executing fourth step; fourthly, distributing target sequence number for the present segment, and storing the position information of the present segment to a structure body corresponding to the target sequence number; fifthly, confirming a first communication segment, uniting the present segment and each non-first communication segment into the first communication segment, and releasing the structure body stored the non-first communication segment. The method can complete unite only needing once scanning, needs not be distributed overfull temporary data cache which can solve technique problem that the prior technique is not suitable for operating in a hardware environment.

Description

technical field

[0001] The invention relates to the field of intelligent video surveillance, in particular to a method and device for scanning connected areas in combined images in the hardwareization of an intelligent video surveillance system. Background technique

[0002] The core content of the intelligent video surveillance system is to detect, track and identify moving objects in the scene. The purpose of detecting the moving target is to find the moving target from the video sequence and extract the shape of the moving target. The detection of moving objects is the first step in intelligent video surveillance, and it is also the basis for subsequent tracking and recognition applications. The speed and accuracy of detection are very important to the entire intelligent video surveillance. In the process of system hardware, the moving object detection algorithm must also take into account the characteristics of hardware implementation, make full use of the parallel adva...
