| Abstract(in English) | The objective of this work is to estimate 3D human pose from a monocular image. We propose a novel retrieval-combination approach that exploits the wide capability of example-based approaches and the flexibility of parts-based approaches. Instead of storing and searching for similar full-body examples, we adopt a half-body representation (i.e., upper-body and lower-body) to reduce a large full-body database into a compact half-body database that has good generalization ability to recover millions of poses by valid half-body combinations. For a given input image, half-body candidates are first retrieved from databases by partial shape matching. Valid half-body combinations of these candidates are selected based on a learned combination constraint, and then we choose the optimal combination(s) in a coarse-to-fine evaluation method. We show good experimental results of pose estimation for both synthetic and real images. Our approach has lower computational and space complexities than example-based approaches and ensures better realistic 3D pose estimates than parts-based approaches. |
