System and method for moving object detection and processing

摘要

A method is provided for an intelligent video processing system based on object detection. The method includes receiving an input video sequence corresponding to a video program, obtaining a plurality of frames of the input video sequence, and obtaining a computational constraint and a temporal rate constraint. The method also includes determining one or more regions of interest (ROIs) of the plurality of frames based on the computational constraint and temporal rate constraint, and selecting a desired set of frames from the plurality of frames based on the ROIs such that the desired set of frames substantially represent a view path of the plurality of frames. Further, the method includes detecting object occurrences from the desired set of frames based on the selected desired set of frames such that a computational cost and a number of frames for detecting the object occurrences are under the computational constraint and temporal rate constraint.

1. A method for an intelligent video processing system based on object detection, comprising:
receiving an input video sequence corresponding to a video program; obtaining a plurality of frames of the input video sequence; obtaining a computational constraint and a temporal rate constraint; determining one or more regions of interest (ROIs) of the plurality of frames of the input video sequence based on the computational constraint and temporal rate constraint; selecting a desired set of frames from the plurality of frames based on the ROIs such that the desired set of frames substantially represent a view path of the plurality of frames; and detecting object occurrences from the desired set of frames based on the selected desired set of frames such that a computational cost and a number of frames for detecting the object occurrences are under the computational constraint and temporal rate constraint; wherein: the computational constraint specifies an upper bound on a total processing time consumed by determining the one or more ROIs, selecting the desired set of frames and detecting the object occurrences; and the computational constraint and the temporal rate constraint are automatically determined according to operational parameters and computational capacity of the intelligent video processing system.
