Title of the talk : Human Activity Recognition - Dance Modelling and Analysis

Abstract: Dance experts often view dance as a hierarchy of information, spanning low-level (raw images, image sequences), mid-levels (human poses and bodypart movements), and high-level (dance genre). We propose a Hierarchical Dance Video Recognition framework (HDVR). HDVR estimates 2D pose sequences, tracks dancers, and then simultaneously estimates corresponding 3D poses and 3D-to-2D imaging parameters, without requiring ground truth for 3D poses. Unlike most methods that work on a single person, our tracking works on multiple dancers, under occlusions. From the estimated 3D pose sequence, HDVR extracts body part movements, and therefrom the dance genre. The resulting hierarchical dance representation is explainable to experts. To overcome noise and interframe correspondence ambiguities, we enforce spatial and temporal motion smoothness and photometric continuity over time. We use an LSTM network to extract 3D movement subsequences from which we recognize dance genre. For experiments, we have identified 154 movement types, of 16 body parts, and assembled a new University of Illinois Dance (UID) Dataset, containing 1143 video clips of 9 genres covering 30 hours, annotated with movement and genre labels. Experimental results demonstrate that our algorithms outperform the state-of-the-art 3D pose estimation methods, which also enhances our dance recognition performance.

Title of the talk : Privacy-aware Multimedia Analytics

Abstract :In this talk, we present our research on privacy-aware multimedia analytics. We will present three works covering different aspects of multimedia analytics. The first work is about privacy protection against machines. Utilizing machine learning and big data, algorithms often act as a tool for privacy violation, by automatically selecting content with sensitive information, such as photos that contain faces or vehicle license plates. The key idea is to perturb images using adversarial machine learning to protect image attributes privacy, while ensuring the images are not degraded. We conducted an experimental study to explore factors that influence human sensitivity to visual changes, which led to the concept of a human sensitivity map. Using this map, a human-sensitivity-aware image perturbation model is developed that can subtly alter an image such that sensitive attributes like gender are misclassified. The second work concerns privacy-preserving analytics on images. Attributes such as emotions, gender and age in images and videos are important for many applications. Existing methods extract this information from faces in the images. However, faces raise serious privacy concerns as they reveal people's identity. We first did an eye-tracking based human study of age, gender, and emotion prediction of people in images under various identity preserving scenarios - obfuscating eyes, lower face, head or the full face. Motivated by this study, we successfully developed a deep learning model for attributes prediction under privacy-preserving conditions and we present its results. The third work concerns training machine learning models where data sets cannot be shared due to privacy regulations (e.g., from medical studies). A simple yet unconventional approach for anonymized data synthesis can enable third parties to benefit from such valuable data. We propose learning implicitly from visually unrealistic, task-relevant stimuli, which are synthesized by exciting the neurons of a trained neural network. Neuronal excitation serves as a pseudo-generative model, and can be extended to inhibit representations that are associated with specific individuals, thus providing privacy. The stimuli data is then used to train new classification models. Experiments on MNIST and sleep apnea data show that these models offer protection against adversarial association and membership inference attacks. We will end with a general discussion on privacy concerns related to multimedia analytics.
