Claim 0:
1. A method, in a data processing system comprising at least one processor and at least one memory, wherein the at least one memory comprises instructions that are executed by the at least one processor to configure the at least one processor to implement an action-object interaction detection mechanism for recognizing actions in cluttered video scenes, the method comprising:
processing frames in an action-object interaction video to generate an object bounding contour, associated with an object of interest, in a set of frames of the action-object interaction video;
for each frame in the set of frames:
refining the object bounding contour of the frame using knowledge of the object of interest thereby forming an associated refined object bounding contour; and
cropping the frame based on the associated refined object bounding contour, thereby forming a set of cropped frames from the cropping of each frame in the set of frames; and

generating an output indicating whether a specified action is detected as being performed in the action-object interaction video based on a processing of the set of cropped frames.
