3D object recognition techniques based on local surface features are widely used for robust recognition. This paper proposes a 3D object recognition technique named 3DU using local features computed based on the uniqueness of keypoints. The ...

Digital preservation of Cultural Heritage (CH) sites is crucial to protect them against damage from natural disasters or human activities. Creating 3D models of CH sites has become a popular method of digital preservation thanks to advancements in ...

Segmentation and classification of clothes in real 3D data are particularly challenging due to the extreme variation of their shapes, even among the same cloth category, induced by the underlying human subject. Several data-driven methods try to ...

Visual-based human action analysis is an important research topic in the field of computer vision, and has great application prospect in sports performance analysis. Currently available 3D action analysis datasets have a number of limitations in ...

Human body postures are an important input modality for motion guidance and other application domains in HCI, e.g. games, character animations, and interaction with public displays. However, for training and guidance of body postures prior research had ...

Most applications involving gaze-based interaction are supported by estimation techniques that find a mapping between gaze data and corresponding targets on a 2D surface. However, in Virtual and Augmented Reality (AR) environments, interaction occurs ...

Volume rendering by ray casting is a computationally expensive problem. For interactive volume visualization, rendering has to be done in real time (3D frames/sec). Since the typical 3D dataset size is at least 128/sup 3/, the use of parallel processing ...
