| Attribute |
Vehicle or LP parameter: brand, model, color, LP number, etc. |
| Base64 |
A standard for encoding binary data (in the context of the CARS_API – images) using 64 ASCII characters. |
| Bestshot |
The best shot of an object (car, smoke/fire, or animal). |
| Bounding box (BBox) |
A rectangle that bounds the image space containing a detected object (vehicle, LP, pedestrian, animal). |
| CARS_Analytics |
Subsystem for collecting, storing, and displaying the results of the CARS_API and CARS_Stream operations via a web interface. |
| CARS_API |
Subsystem for detection and recognition of vehicle and LP attributes on images in real-time. |
| CARS_Stream |
Subsystem for detecting and tracking vehicles, LPs, pedestrians, and animals in the video stream and determining the best frames. |
| Classifier |
An object in the CARS_API subsystem that recognizes one of the attributes of a vehicle or LP. |
| Crop |
An object cut from a fullframe (car, smoke/fire, or animal). |
| Detection |
The process of identifying areas of the image containing vehicles or LPs. |
| Detector |
An algorithm for identifying areas in the image that contain vehicles or LPs. |
| Event |
A type of CARS_Analytics work scenario in which the object is considered detected and recognized, but does not require attention to each individual case. |
| False Positive Detection |
A detection result where an object that is not a vehicle or LP is incorrectly identified as a vehicle or LP. |
| False Negative Detection |
A detection result where a vehicle or LP is not detected or identified as a vehicle or LP. |
| Foreground subtraction (FGS) |
A technology that subtracts the background of an image and processes only the region with moving objects. It is used to improve the performance of the system. |
| Full frame |
Full frame from the camera. |
| Handler |
An algorithm that determines the logic of frame processing. Used for creating scenarios. |
| Incident |
A type of CARS_Analytics work scenario in which the object is considered detected and recognized, but at the same time require attention to each individual case. |
| Inference |
Image processing by the neural network and generation of results: detection coordinates and the probability that the detection is an object of interest (vehicle, LP, smoke, fire, pedestrian, or animal). |
| Intersection Over Union (IOU) |
Parameter determines the coefficient of intersection of two detections. |
| License Plate (LP) |
An individual alphanumeric designation assigned to a vehicle by a registration authority. |
| LUNA CARS |
A system designed for detection, tracking, and recognition of vehicle and LP attributes. The system consists of three subsystems: CARS_Analytics, CARS_API, and CARS_Stream. |
| Model FGS |
The static part of the video stream, or the background of the video stream, with no moving objects. |
| Nginx |
A load balancer that distributes requests and responses between running instances of the CARS_API and external systems. |
| Non-Maximum Suppression (NMS) |
An algorithm for determining the boundaries of objects in an image. |
| Object |
An item of interest for the system within the processes of detection, re-detection, and tracking: vehicle, license plate, smoke, fire, pedestrian, or animal. |
| Real Time Streaming Protocol (RTSP) |
A transport-layer data transfer protocol in connectionless networks that provides the delivery of datagrams without requiring confirmation of their receipt. |
| Redetection |
The process of re-identifying areas of an image containing vehicles or LPs. |
| Reidentification |
Repeated action to identify an object in order to «glue» the broken tracks of the same object into one. |
| Scenario |
System customization for generating events and incidents based on handlers. |
| Track |
Information about the position of a vehicle and LP across a sequence of frames. |
| TrackEnd |
Event about the end of tracking an object (car, smoke/fire, or animal). |
| Tracking |
The process of obtaining information about the position of a vehicle or LP across a sequence of frames. |
| Transmission Control Protocol (TCP) |
A real-time streaming protocol that contains a simple set of basic commands for controlling the video stream. |
| Vehicle |
A mechanical device used for transporting people and/or goods, which requires a special right to operate. |
| User Datagram Protocol (UDP) |
A transport-layer data transfer protocol in connectionless networks that provides the delivery of datagrams without requiring confirmation of their receipt. |
| WebSocket (WS) |
A communication protocol over TCP connection designed to exchange messages between a browser and a web server using a persistent connection. |
