For decades, video surveillance has been used to detect and stop crimes in homes, businesses, and public places. However, the traditional video surveillance system is nothing more than a lifeless eye. The amount of work left for humans is still very large. In the future, artificial intelligence will make surveillance cameras more "smart", thus reducing the manpower and material resources needed to combat illegal crime more effectively. Compared with traditional video surveillance technology, what are the advantages of artificial intelligence technology?
Recalling the history of artificial intelligence in the past decade has been magnificent, especially an exciting thing, but a better future has not yet arrived. When we are ready to enter the door of 2018, a lot of changes in artificial intelligence are already in the making, especially the video surveillance technology led by artificial intelligence.
Researchers in the field of artificial intelligence have demonstrated excellent progress in machine learning and artificial intelligence over the years. The addition of artificial intelligence has revolutionized urban life: image recognition technology is helping doctors improve the accuracy of diagnosis; smart retail is rejuvenating people’s consumer experience, and forms such as self-pay orders have become part of the new game of “hand-out partyâ€; auto-pilot technology is also It will help people determine road conditions and accurately select the best route from home to company. In the context of the implementation of many applications in cities, economic development and changes in people’s lifestyles are pushing for more breakthroughs in artificial intelligence applications. Whether it is IBM’s Watson who defeated the world’s smartest man in the quiz show Jeopardy, or is an artificial intelligence platform from China surpassing humans in IQ tests or Google’s artificial intelligence The poet wrote his own beautiful poetry, and numerous examples can prove the greatness of artificial intelligence technology.
At present, in addition to major breakthroughs in areas such as health care, energy and power, transportation and space, and linguistic image recognition, artificial intelligence technology will also promote positive industrial development in the field of security. Specifically, artificial intelligence will light up a brand new skill tree to help the police effectively monitor the video and thereby crack down on a series of illegal crimes.
We will see the specific progress made by artificial intelligence in the security field. Below, I will introduce several aspects in detail.
First, artificial intelligence can overcome human attention deficits
Entrepreneur Bob Beechler explained: “A problem that should not be underestimated by human food surveillance operators is attention fatigue.†The human brain always alternates naturally between attention and attention and cannot 24 hours to maintain a high degree of concentration, accurate and efficient monitoring of all scenes; and in video surveillance, distractions will lead to a variety of terrible consequences. So what if we have an artificial intelligence monitoring system that will not be disturbed by attention fatigue and reduce errors by working with humans?
This is the positive change that artificial intelligence can bring us in video surveillance.
Although video surveillance technology already exists and allows people to play back historical video recordings when they need it, it has never told human surveillance operators: "Hey, this video does not look right!" Manual playback viewing surveillance video It is a very inefficient matter that requires a lot of manpower and material resources. The artificial intelligence video monitoring system allows users to free themselves from the burdensome watching and monitoring work and to make efficient and accurate decisions with ease.
Just last year, Movidius, a US machine vision development company, and Hikvision, a security hardware manufacturer in the United States, announced their intention to cooperate and collaborated in the production of an artificial intelligence video surveillance camera with a deep neural network that will be detected at the camera. Sends notifications to humans when specific events occur and provides a series of real-time alerts.
To give a practical example - when the camera of this artificial intelligence monitoring system monitors a store, it will notice that the same person repeatedly wanders around the same place within a given time range, or returns to the same place several times. In a series of actions, the monitoring system will determine the property that the target object may be in the stolen store. This is the difference between humans and artificial intelligence: the camera will find this behavior abnormalities and alarms, and conduct further investigations, and due to attention fatigue, human monitoring operators may not even notice these behaviors.
Second, artificial intelligence has powerful facial recognition capabilities
After the occurrence of illegal activities, people often need to make difficult examinations of video content in order to find out who the criminal suspect is. More unfortunately, only when the police identify the suspect's facial features on the screen can he further confirm his identity. Advanced artificial intelligence software such as MegaFace can change this situation.
MegaFace is an ongoing artificial intelligence project at the University of Washington. It received a huge dataset training with nearly 672,000 photo-ebookers and nearly 5 million images. Almost all of the images in the dataset came from Flickr. In previous tests, the system was able to match two photos of the same person in a data set of one million facial images, with an accuracy of 75%. And if the system has 10 chances, the accuracy of facial recognition will increase to 90%.
Obviously, facial recognition systems have a lot of potential value. It can be combined with video surveillance systems. As a result, law enforcement personnel can help identify and identify the faces of target personnel in the crowd. This may help the police to trace the criminals in the future, and even prevent them from happening. Organize crimes from the source.
Artificial intelligence makes decisions on crime in real time
Artificial intelligence monitoring system can not only be used in the police's late investigation, but also can detect and track criminal behavior in real time. For example, the artificial intelligence video surveillance system developed by Movidius can find unattended objects in practical applications such as airports and train stations. The camera can identify unattended packages, track when they are initially left alone, and issue warnings so that on-site security personnel are highly vigilant about related suspicious activities.
Another practical example is an anti-theft camera system that is trained to recognize the body language and movement that a thief would normally have before stealing. When these behaviors are identified, the system will prompt the security team to deploy personnel to check the situation on the site to prevent theft.
The future of artificial intelligence and video surveillance systems
Just as there are great potentials in many other industries and fields, the role of artificial intelligence in the security field is equally worth looking forward to. Whether it is the enterprise's loss prevention department to monitor offline stores, homeowners to protect their personal property, or law enforcement personnel to identify illegal acts, its application scenarios are very rich.
Believe me, the development of artificial intelligence in the security field in the next few years will be very exciting.
