Based on the database of the hand drawn three-dimensional reconstruction

Since more and more motion data are created, the reuse of motion data becomes increasingly important. We present a method to reconstruct a 3D CEgure animation based on 2D user-deCEned moiton on our motion database. First, a novel interactive interface for deCEning the input query is persented. Users can draw a series of stick CEgure of 2D human motion through it. These actions have a certain mount of key points. Second, we use our search algorithm based on Principal Component Analysis(PCA) and Graphics Processing Unit(GPU) to CEnd appropriate database frames. Then, we use these frames to reconstruct 3D frames. Our system can produce the primary animation for additional reCEnement.
