ABSTRACT: Single Stage Convolutional Neural Networks (CNNs) have been lately dominating the field of object detection due to their real-time inference speeds while exhibiting competitive performance with heavy state-of-the-art multiple-stage models. In this paper, we use CNNs for gesture detection as a public security measure and equip them with microcontrollers to transform detections into meaningful by emitting light and sound signals. Particularly, we use a modified form of YOLOv3 (Redmon & Farhadi, 2018) to target small-scale object detection suited for frames captured from surveillance cameras. We train the model using over custom annotated images and the results demonstrate good generalizability. We integrate the model with ESP8266 and camera module to build a functional alarm system that can alert, record, and send detections using mailing systems.
