RADU IONESCU, SecurifAI

About us

In recent years, criminal organizations, terrorist and radical groups have posed a significant threat to the modern society. Recent attacks in major cities around the world have brought many casualties among innocent citizens. Put together, all these facts indicate that we need increased security standards in order to protect our modern society and prevent the degradation of the geopolitical situation at the global level. However, increasing security personnel in certain areas does not necessarily make people feel safer, as the respective area can be seen as very unsafe. In this context, we believe that intelligent video surveillance software can increase the security standards around the world, without requiring more security personnel.
Usually, security alerts are provided by well-intended people witnessing an event that threatens their security or, sometimes, by security personnel present at the scene by chance. In many cases, the alerts are not timely provided for an efficient intervention. In some cases, for example when robberies happen during the night, the event is reported long after it has occurred. Inefficiency in the relay of information directly from the scene leads to increased response times, which in turn may even result in human casualties.

We envision a safer world, one where the people are able to enjoy life in their own cities without being afraid of potential attacks, robberies, or life-threatening events. Our aim is to bring the next generation of intelligent video surveillance software to our clients and users. The SecurifAI video surveillance software is designed to work in various environments and to be easily adapted to different scenarios. Our software is able to automatically detect possible life-threatening situations or events, and deliver timely security alerts to security personnel.

Our Systems

We automatically detect abnormal events by learning a model of normal events from training video.

Abnormal event detection in video is a challenging task in computer vision, as the definition of what an abnormal event looks like depends very much on the context. For instance, a car driving by on the street is regarded as a normal event, but if the car enters a pedestrian area, this is regarded as an abnormal event. A person running on a sports court (normal event) versus running outside from a bank (abnormal event) is another example. Although what is considered abnormal depends on the context, abnormal behaviour should be represented by unexpected events that occur less often than familiar (normal) events.
Hence, our approach to abnormal behavior detection is based on learning a model of familiarity from a given training video and label events as abnormal if they deviate from the model. We employ deep convolutional neural networks and support vector machines to achieve state-of-the-art results for the abnormal event detection task. Our system is flexible and can be adjusted to reach a desirable trade-off between true and false detections.

We automatically detect unattended luggage in public areas using background subtraction, motion tracking and deep learning.

In many airports and public areas, people are instructed to keep their personal belongings attended at all times. Criminals can use their luggage to hide bombs in public places and leave the scene before the bomb explodes. Hence, any unattended luggage is a potential threat to the people passing by. To automatically detect such threats, we first employ background subtraction and motion tracking to spot stationary objects.
We then employ our convolutional neural network trained to distinguish between abandoned luggage and other stationary objects, for example sleeping persons or parked cars.

Our face detector is designed to work in real-time, while producing highly accurate face detections.

Face detection is a very well-studied task in computer vision and, hence, there are many systems that can accurately detect faces. We considered a state-of-the-art system based on deep features able to detect faces in real-time. The system is trained on tens of thousands of images for improved accuracy.
Although the face detection system can be employed for many other tasks, for example face recognition or people counting, we use the detected faces as input for the facial expression recognition system and the contactless heart rate estimation system.

Our face recognition system can reliably recognize persons from a single photo of each subject.

Face recognition is perhaps one of the most important problem that requires solving in the context of video surveillance. Face recognition systems usually need many training image samples, before recognizing the people in the provided training data. However, in real-life scenarios, there are only a few images (most-likely only one image) available for a certain person of interest (that needs to be recognized).
In this context, we specifically designed our system based on convolutional neural networks to recognize a person in video even when there is only a single training photo available for the respective person. Our face recognition system can also be used for face authentication. In this case, we can verify if a person user tries to impersonate a known user using a printed photo by employing the contactless heart rate estimation system.

Our facial expression recognition system ranked 4th in the Facial Expression Recognition Challenge of the WREPL Workshop of ICML 2013.

Before committing a crime, a person may feel angry or disgusted about what is about to happen. Our facial expression recognition system uses both handcrafted and automatically-learned features to deliver an accuracy higher than human-level performance. We improve our performance by constructing a recognition system on the fly, tailored to each image that needs to be analyzed. We are proud to report that a preliminary version of our system (that uses only handcrafted features) ranked on the 4th place among 56 teams around the globe, in the Facial Expression Recognition Challenge of the WREPL Workshop of ICML 2013.
Our system is able to distinguish among 8 standard facial expressions: anger, contempt, disgust, fear, happiness, sadness, surprise, and neutral. The output provided by the facial expression recognition system can be corroborated with the output of the contactless heart rate estimation system in order to retain a suspect for questioning.

We automatically analyze the small changes in the light reflected by the face skin while the blood pumped by the heart inflates the small vessels under the skin.

Recent developments in computer vision and signal processing have enabled an interesting application, namely the heart rate estimation of a person using contactless technology. We only need a few seconds of video recording with the subject’s face. We first eliminate the noise that naturally occurs in digitally recorded images. We then analyze the small changes in the light reflected by the face skin while the blood pumped by the heart inflates the small vessels under the skin.
Security personnel can use our system to track suspects and check their pulse rate without the subjects’ acknowledgment. A high pulse rate is an indicator of anxiety, stress, anger, in which case the security personnel can retain the suspect for questioning.

Our pedestrian detection and tracking system is based on fast convolutional neural network components that deliver real-time processing.

The pedestrian detection and tracking system is based on the same components as the car detection and tracking system. In the detection stage, we use a deep single-stage convolutional architecture that provides fast and accurate detections. For short-time tracking, we use a state-of-the-art handcrafted object tracker, which we improve by applying a deep pedestrian classifier.
For long-time tracking, we employ a siamese neural network to match the short-time tracklets. Our pedestrian detection and tracking system can be used for people counting or to ensure the security in no-entry zones.
