Latest Patents
One of Lexing Xie's latest patents is titled "Unsupervised learning of video structures in videos using hierarchical statistical models to detect events." This method learns the structure of a video in an unsupervised setting to detect events consistent with that structure. It involves selecting sets of features from the video, updating a hierarchical statistical model based on these features, and evaluating the information gain of the model. Redundant features are filtered out, and the model is updated accordingly. A Bayesian information criterion is applied to rank order the models and feature sets for effective event detection.
Another notable patent is "Structural analysis of videos with hidden Markov models and dynamic programming." This method analyzes the high-level syntax and structure of continuous compressed videos by utilizing a plurality of states. It begins with training a set of hidden Markov models for each state using a segmented training video. Domain-specific features are then extracted from a fixed-length sliding window of the continuous compressed video. Maximum likelihoods are determined for each set of features using the trained models, and dynamic programming is applied to ascertain specific states for each window of frames.
