Explore the mysteries of the six major applications of intelligent video surveillance

    Facing the massive amount of video data information, it undoubtedly brings more pressure to the security big data information processing. If high-definition is no longer the only development direction of security, then only intelligent monitoring can keep pace with it. So behind the security big data, what kind of development will intelligent monitoring have, and what killer features will security companies use? Today, let's discuss the six major applications of intelligent monitoring.

    The reason why the field of security monitoring is intelligent is to meet the increasingly demanding needs of users on the one hand, and to reduce labor costs on the other hand. As more and more places popularize monitoring facilities and high-definition monitoring, massive data information and complex video retrieval will follow. How to find the most core information in security big data, intelligent monitoring has made a grand debut.

    Uncover the secrets behind big data: six applications of intelligent monitoring

    Intelligent monitoring-image enhancement and restoration

    Does the surveillance camera in your community have the symptoms of "blindness", especially at night, when the surveillance camera images are pitch black or white in low-light environments. Obviously, in low-light environments, image augmentation technology should make up for the defects.

    As the industry analysis shows, the image enhancement algorithm can effectively improve the image quality problems caused by lighting, fog and other reasons, and significantly improve the image details. Simply put, this is an image optimization technology. In addition to image enhancement, there is also an image restoration technology that is particularly suitable for night vision monitoring, but this capture environment is more targeted.

    Identify fast-moving vehicles in the lane

    Image restoration technology is more suitable for capturing fast-moving objects, such as moving cars. If you want to capture license plate information correctly and completely, you can model the process of image blur caused by focusing, movement, etc., and use the deconvolution algorithm to reverse the original image information. This can partially restore key information such as license plate text and face.

    For example, the license plate capture includes the following information: the most important is the license plate number, license plate color, letters, text, etc., especially for the easily confused number "0" and letter "Q", the processing system needs to treat it specially. Of course, some monitoring probes not only capture license plate information, but also have speed measurement functions embedded, which is definitely a "thunder" for drivers.

    Smart Monitoring-Condensed Playback

    When surveillance cameras are not equipped with intelligent analysis modules, most cameras only have basic recording functions. When dealing with emergencies, the surveillance system often lags behind. For example, if the police need to retrieve video data within a week, it will take a long time to watch them minute by minute, not to mention how much video data there is. In the future, it will be possible to extract key data information from massive video information, and condensed playback will come into being.

    Video intelligent retrieval

    Condensed playback literally means quickly browsing video information. But how does the video system do it in actual applications? First, the video is condensed to generate a summary and the original image is set up; then several hours of video clips are compressed into a few minutes of condensed video; then the objects that appear at different time points in the video are superimposed on the same screen; finally, they are played and marked according to the different time points of their appearance. This condensed playback and quick extraction of effective information greatly improves the search efficiency.

    The most common intelligent monitoring - face retrieval

    Unlike face recognition, face search is to provide the facial image information of the person to be searched, search in a huge database, find similar-looking people through face database search and comparison, and then make a judgment. This is a common way to quickly confirm identity.

    Face search can be used to search the permanent population database, key personnel database, drug addict database, etc. to quickly confirm the identity. It can also search the fugitive database to realize case analysis. In addition, it can also analyze and compare identity cards, temporary residence permits, household registration certificates, etc. to find problems such as multiple certificates for one person.

    Smarter than face recognition - face and body attribute analysis

    In addition to face retrieval, we are also familiar with face recognition. However, there is now a more intelligent face recognition method that not only includes the face, but also some human attributes. For example, the captured person's gender, age group, height, and whether he wears glasses. Such detailed face recognition will further locate the person to be retrieved.

    Face and body attribute analysis is to automatically capture faces through face capture machines. Combined with binocular stereo vision technology, human attribute features are extracted, and these features are exactly the ones I mentioned above. This kind of human attribute analysis is mostly used by public security agencies to screen suspicious people, or for commercial analysis of shopping malls and business districts with large traffic.

    3D stereo recognition is smarter

    Compared with traditional face recognition, three-dimensional recognition is more intelligent. This three-dimensional recognition detection method can check whether there are people in the house and the number of people; in addition, it can also locate and track the movement path of people in the house; even smarter, it can determine whether the person is standing or lying on the ground through intelligent analysis, and issue a timely warning. This type of three-dimensional recognition is suitable for small indoor scenes, road prison interrogation rooms, vault scenes, etc.

    Intelligent monitoring upgrade: vehicle face search

    At the beginning of the article, the author introduced the image restoration technology, which is particularly suitable for license plate recognition. Often, some cunning criminals may use fake license plates, which brings great trouble to solving the case. The law is long and will not let criminals take advantage of it. The new vehicle face search function can determine whether the suspect has modified or replaced the license plate. The vehicle face search also inputs a sample image to find similar vehicles and license plate numbers to achieve a quick search function.

    The above are the six major applications based on intelligent high-definition monitoring. Whether it is image upgrade or recognition method upgrade, it ultimately further highlights the role of intelligent monitoring on the basis of high definition. Regarding intelligence and high definition, there are still many technical applications worth exploring.
