1. A method for an intelligent user-interaction system based on object detection, comprising:

  • receiving an input video sequence corresponding to a video program;

    dividing the input video sequence into a plurality of video shots, each containing one or more video frames;

    detecting possible object occurrences in each of the plurality of video shots;

    analyzing possible paths of an object in a video shot using a multimodal-cue approach;

    aggregating the path-based selected object occurrences across the plurality of video shots to detect objects; and

    generating a complete list of the object occurrences across the plurality of video shots;

    wherein analyzing the possible paths using a multimodal-cue approach further includes;

    combining an appearance cue, a spatio-temporal cue, and a topological cue to aid object detection in the plurality of video shots;

    dictating a usage of an object'"'"'s visual features to detect possible object locations in a video frame using the appearance cue;

    injecting information across a sequence of frames via relational constraints between a target object class and a related object class using the spatio-temporal cue and the topological cue;

    fusing the multimodal cue information to create links between object occurrences across the video frames in a current video shot; and

    applying dynamic programming to find optimal object paths.
