摘要： A system and method are provided for analyzing a video. The method comprises: sampling the video to generate a plurality of spatio-temporal video volumes; clustering similar ones of the plurality of spatio-temporal video volumes to generate a low-level codebook of video volumes; analyzing the low-level codebook of video volumes to generate a plurality of ensembles of volumes surrounding pixels in the video; and clustering the plurality of ensembles of volumes by determining similarities between the ensembles of volumes, to generate at least one high-level codebook. Multiple high-level codebooks can be generated by repeating steps of the method. The method can further include performing visual event retrieval by using the at least one high- level codebook to make an inference from the video, for example comparing the video to a dataset and retrieving at least one similar video, activity and event labeling, and performing abnormal and normal event detection.

摘要： Systems and methods are described to analyze visual data and trajectory data from sports and games, to determine the content of the input data and detect actions and events, quantitatively measure their impact on the future activities and events and make predictions. In real-time, at every moment of the game, the probability of the next action/event in the game is estimated; the impact of the current state of the game on the future outcomes are predicted; and the current player action/match event is labelled. More specifically, given a predefined objective, a quantitative value is assigned to the input data based on the current observation characterizing the probability of reaching an objective, or incremental changes to that probability based on the observed state of the game from the video or trajectory data.

摘要： A method is described, for processing images of persons or objects to generate an identity preservative feature descriptor learnt for each person or object. The method includes obtaining an image of a person or object, extracting at least one spatial attribute of the person or object from the obtained image, and extracting at least one appearance feature of the person or object from the image by using a mapping function to translate image pixels into appearance attributes represented by at least one numerical feature. The method also includes combining the at least one spatial attribute and the at least one appearance feature to generate the unique feature descriptor representing the person or the object, to assign the unique feature descriptor to the image to enable feature descriptors representing the same person or object to be compared to feature descriptors representing different people or objects given a predefined mathematical pseudo-distance metric according to a least a distance from each other.

摘要： There are provided methods and systems to generate a summary of a video by decomposing the video into segments automatically, where each segment has a quantitative score. The assigned scores to those segments can be generated using models that are quantitatively describing and/or evaluating the individual or group activities of the objects in the scene. The segments can be grouped based on their scores to generate a video summary. In an implementation, such a system can generate video summaries of a game based on the quantitative game models. Using a game model that assigns values to different game events and actions in a game, a set of most interesting, least interesting and neutral plays can be identified in the video and a highlight or lowlight reel generated. With adjusting the valuation of player actions and game events based on their impact on the game's result, the monotony in highlight reels can be avoided. The video segments can also be used to generate a playlist of the different plays in game ordered based on their assigned scores.
