Abstract

Deep learning-based action classification technology has been applied to various fields, such as social safety, medical services, and sports. Analyzing an action on a practical level requires tracking multiple human bodies in an image in real-time and simultaneously classifying their actions. There are various related studies on the real-time classification of actions in an image. However, existing deep learning-based action classification models have prolonged response speeds, so there is a limit to real-time analysis. In addition, it has low accuracy of action of each object if multiple objects appear in the image. Also, it needs to be improved since it has a memory overhead in processing image data. Deep learning-based action classification usingone-shot object detection is proposed to overcome the limitations of multi-frame-based analysis technology. The proposed method uses a one-shot object detection model and a multi-object tracking algorithm to detect and track multiple objects in the image. Then, a deep learning-based pattern classification model is used to classify the body action of the object in the image by reducing the data for each object to an action vector. Compared to the existing studies, the constructed model shows higher accuracy of 74.95%, and in terms of speed, it offered better performance than the current studies at 0.234 s per frame. The proposed model makes it possible to classify some actions only through action vector learning without additional image learning because of the vector learning feature of the posterior neural network. Therefore, it is expected to contribute significantly to commercializing realistic streaming data analysis technologies, such as CCTV.
