Keenly priced technology makes AI accessible to all

According to Uri Guterman, Head of Product & Marketing for Hanwha Techwin Europe, deep learning AI is no longer an emerging technology which is only suitable for high security or mission critical video surveillance cameras.

Guterman believes that many people who are not involved in video surveillance projects involving deep learning AI might be under the impression that the technology is too expensive to be deployed for anything other than high-end applications.

“With the introduction of a new generation of affordable cameras supplied with deep learning AI onboard, this is far from being the case.” stresses Uri Guterman. “However, the jargon associated with the technology, such as artificial neural networks and machine learning, may certainly have created the impression that the capabilities of what the technology can deliver go way beyond what the majority of end-users require to achieve maximum benefit from their video surveillance solutions.”

Making false alarms a thing of the past

Here, Uri Guterman explains the case for a much wider use of deep learning AI beginning with the age old problem of trying to eliminate false alarms.

“In simple terms, deep learning AI video analytics ignores video noise, waving trees, moving clouds and animals, all of which might normally be the cause of false alarms when standard motion detection technology or sensors are being used to detect activity, because it has not been trained to look out for them.

This higher level of performance of deep learning AI based video analytics means control room operators and security personnel can focus on responding to real incidents and emergencies and not waste time and effort on false alarms. In addition to extreme accuracy, deep learning also allows operators to search for specific features and attributes, including a person’s age group and gender, and whether they are wearing glasses, a hat, or carrying a bag.”

Easy set up and use

According to Hanwha, because the AI technology is already built into specific cameras, there is nothing at all complicated about installing, setting up and using deep learning AI. System integrators should therefore be able to put the technology to good use as part of virtually any video surveillance project.

With AI ready to work out of the box, albeit with the opportunity to customise it to reflect an end-user’s operational requirements, there is no real need for users to get to grips at a deep technical level with how it works.

Deep Learning is more sophisticated than traditional analytics

However, it is interesting to look at an overview of Hanwha Techwin’s definition of the technology and how it works.  “Deep learning is part of machine learning and is a way of achieving artificial intelligence by training a machine to perform tasks based on a large number of examples. To do this, deep learning uses multi-layered or deep artificial neural networks, which are essentially mathematical models inspired by the human brain. The fact they are deep makes them very suitable for solving complex problems, such as identifying and recognising objects and events in raw video, with extremely high accuracy.”

“As an example, being able to correctly establish the gender of a person requires expert Hanwha Techwin R&D engineers to design, train and validate a deep learning network which, during the training stage uses a database of millions of suitably selected faces, each of which is tagged with its known true gender. After several days of training by our engineers, the neural network is ready to be put to work and is likely to have an accuracy of approximately 98%, which is about the same as the ability of human beings to do the same thing.

Deep Learning AI techniques offer a far superior performance compared to more traditional video analytics. The latter are usually based on motion detection and are therefore not sophisticated enough to detect static objects such as parked vehicles or cope with video noise, such as light pollution from headlights or moving shadows, all of which are causes of false alarms.”

The company has also found that the performance of the analytics is just as impressive in fast moving or very busy environments, which improves the forensic search for evidence and speeds up investigations.  It is for this reason that Guterman believes deep learning AI will inevitably gradually replace traditional video analytics, particularly in cases where false alarm are a challenge.

“Deep Learning AI is particularly suitable for applications which require a greater degree of sophistication than that offered by traditional video analytics. It enables, for example, retailers to capture and analyse business intelligence such as age and gender, allowing them to granularly analyse customer demographics and in doing so, gain a greater understanding of customer behaviour and buying patterns.”

Improving lives and productivity

One of the most topical examples in recent times is the fact that Deep Learning AI has made a valuable contribution to society during the Covid pandemic, as it has been at the heart of face mask detection, distance measuring and occupancy monitoring applications.

“In addition to helping combat criminal activity, there are countless ways edge-based Deep Learning AI video analytics can help businesses improve productivity and operate safely in a pandemic affected world. With the recent availability of more keenly priced cameras equipped with the technology, users can now expect a high return on investment, regardless of how they capitalise on the technology,” concludes Uri Guterman.
