Abstract:Inertial measurement unit (IMU) data has proven to be quite successful in the field of activity recognition, both on human and animal activities. This IMU data can be gathered relatively easily from animals using collars with sensors. However, for training accurate models a large amount of this data needs to be labeled, which is a very expensive and time-consuming process. To overcome the issue, researchers have come up with several ways to generate IMU data from video, as labeled video data is abundantly available. Previous approaches mainly make use of pose estimation and forward kinematics. In this paper, however, the viability of using end-to-end deep learning for generating IMU data is evaluated. This research consists of two parts, the first part will be to use end-to-end deep learning to generate IMU data from video data. The second part will be to train an animal activity recognition(AAR) model to evaluate the effects of adding generated IMU data to the training data of the AAR model. In this research is shown that, albeit with a fairly small dataset with a limited amount of activities, there are indications that IMU data generated from video using neural networks can contribute to the training of an AAR model.
