Abstract

This disclosure introduces an automated computer system designed to detect fire and smoke in video frames. Within this system, an object detection model is trained to recognize fire and smoke patterns. In a post-training evaluation phase, the system utilizes the model to determine an instance-level detection threshold from a validation set, which dictates the minimum confidence score required for a fire or smoke designation. In addition, a frame-level detection rule is defined, considering both the cumulative count of detected fire or smoke instances and their associated confidence scores. During inference, the system processes video frames through the model, designates detected patterns with bounding boxes, and subsequently applies the instance-level threshold and frame-level rule. When a sequence of frames fulfills a predetermined criterion, the system activates an alarm.
