System And Method For Detection Of High-Interest Events In Video Data

摘要

A method for event identification in video data includes identifying a feature vector having data corresponding to at least one of a position and a direction of movement of an object in video data, generating an estimated feature vector corresponding to the feature vector using a dictionary including a plurality of basis vectors, identifying an error between the estimated feature vector and the feature vector, identifying a high-interest event in the video data in response to the identified error exceeding a threshold, and displaying the video data including the high-interest event on a video output device only in response to the error exceeding the threshold.

1. A method for monitoring video data comprising:
identifying a feature vector of an event having data corresponding to at least one of a position and a direction of movement of an object in video data; generating an estimated feature vector corresponding to the feature vector using a dictionary that includes a plurality of basis vectors; identifying an error between the estimated feature vector and the identified feature vector; identifying a high-interest event in the video data in response to the identified error exceeding a threshold; and displaying the video data that includes the high-interest event on a video output device only in response to the identified error exceeding the threshold.
