Retrieval of Motion Capture Data Based on Behavioral Similarity
We propose a novel method for motion data retrieval based on similar behaviors. A complex motion sequence is treated as a concatenation of segments of distinct behaviors. We characterize each motion segment by a set of features that describes the distribution of the poses in the segment, and then use these features as modeling primitives to construct a compact but effective indexing structure. ...
متن کاملSimilarity, retrieval, and classification of motion capture data
Three-dimensional motion capture data is a digital representation of the complex spatiotemporal structure of human motion. Mocap data is widely used for the synthesis of realistic computer-generated characters in data-driven computer animation and also plays an important role in motion analysis tasks such as activity recognition. Both for efficiency and cost reasons, methods for the reuse of la...
متن کاملMotion Similarity Analysis and Evaluation of Motion Capture Data
Motion similarity analysis is a critical stage for the successful reuse of motion capture data. Some previous works use one or multiple motion features, such as the difference between joint positions, joint angles, joint velocities and accelerations to capture the similarity information between two frames of different or the same motion streams. In this paper, two typical motion similarity appr...
متن کاملAn Information Retrieval System for Motion Capture Data
Motion capturing has become an important tool in fields such as sports sciences, biometrics, and particularly in computer animation, where large collections of motion material are accumulated in the production process. In order to fully exploit motion databases for reuse and for the synthesis of new motions, one needs efficient retrieval and browsing methods to identify similar motions. So far,...
متن کاملSelf-similarity Analysis for Motion Capture Cleaning
Motion capture sequences may contain erroneous data, especially when the motion is complex or performers are interacting closely and occlusions are frequent. Common practice is to have specialists visually detect the abnormalities and fix them manually. In this paper, we present a method to automatically analyze and fix motion capture sequences by using self-similarity analysis. The premise of ...
