Perceptually consistent example-based human motion retrieval

Large amount of human motion capture data have been increasingly recorded and used in animation and gaming applications. Efficient retrieval of logically similar motions from a large data repository thereby serves as a fundamental basis for these motion data based applications. In this paper we present a perceptually consistent, example-based human motion retrieval approach that is capable of efficiently searching for and ranking similar motion sequences given a query motion input. Our method employs a motion pattern discovery and matching scheme that breaks human motions into a part-based, hierarchical motion representation. Building upon this representation, a fast string match algorithm is used for efficient runtime motion query processing. Finally, we conducted comparative user studies to evaluate the accuracy and perceptualconsistency of our approach by comparing it with the state of the art example-based human motion search algorithms.
