7 is a diagram exemplarily illustrating a method of determining an abnormal behavior in a captured image.

Referring to FIG. 7 , a method of determining an abnormal behavior using a CCTV video uses a location and/or a movement direction of a person object in the image with a virtual boundary line 421 as a center. The virtual boundary line 421 may be predetermined by an administrator. The virtual boundary line 421, for example, by a combination of the location (or shooting angle) of the CCTV camera 20 and the structure of outdoor facilities, may be arranged at a specific location of the CCTV video. A danger area and a safe area may be divided based on the virtual boundary line 421 .

The intelligent analysis module 320 analyzes the continuous frames of the CCTV video by using the abnormal behavior analysis algorithm. As illustrated in FIG. 7 , assume a situation in which two people move closer to the railing. The intelligent analysis module 320 first detects two independent person objects in the CCTV video. As the direction vectors 422 of the two person objects, that is, the movement directions move toward the virtual boundary line 421 , the intelligent analysis module 320 determines that the position of at least one person object is at the virtual boundary line 421 . It is determined whether it approaches or crosses the virtual boundary line 421 and enters the danger area.

When the person object is located in the danger area including the virtual boundary line 421 , the intelligent processor 340 extracts a frame representing it as a snapshot. Thereafter, the intelligent processor 340 transmits the extracted snapshot to the control server 500 through the communication router 400 .

8 is a diagram exemplarily illustrating a method for determining violent behavior in a captured image.

Referring to FIG. 8 , a method of determining violent behavior using a CCTV video uses a motion vector of a person object in the video. The intelligent analysis module 320 analyzes the continuous frames of the CCTV video by using the violent behavior analysis algorithm. As illustrated in FIG. 8 , when three people move apart from each other, it appears as a group of three person objects. However, if two of them commit an act of violence, the two person objects appear as one person object. In order to group the motion regions into one group in this way, a clustering process is performed, and if a motion vector is analyzed for each grouped group, when a person walks or runs as shown in the image on the left, the motion direction extracted from one grouped region is appear the same However, as shown in the image on the right, in a scene where two people engage in violent acts, it is determined as a group because the two people are attached, and the direction of the motion vector in this grouped area is not constant and collision occurs. As such, it is possible to detect a violent act by focusing on a change in the direction of a motion vector occurring within an area in which two or more person objects are grouped into one group. Violence and non-violence are prevented by observing the sporadically appearing changes in the direction of motion vectors in successive frames through the applied algorithm, determining the weight of the intensity of change in the direction of motion, and applying a threshold value to the accumulated result value. If it is analyzed and recognized as violence, snapshot (image) information for the corresponding video information can be delivered to the server via a communication router.
