Fine-Grained Action Detection and Classification in Table Tennis with Siamese Spatio-Temporal Convolutional Neural Network
Abstract
Human action recognition in videos is one of the key problems in visual data interpretation. Despite intensive research, the recognition of actions with low inter-class variability remains a challenge. To answer this problem, my thesis focus on fine-grained classification challenge using a Siamese Spatio-Temporal Convolutional Neural Network and apply it to a new dataset we have introduced TTStroke-21. Our model take as input data RGB images and Optical Flow and is able to reach an accuracy of 91.4% against 43.1% for our baseline on temporal segmented videos. Detection and classification in videos using a sliding temporal window leads to a score of 81.3% over the whole dataset.
