Visibility computation through image generalization
… of pixels in the image reports a visible geometric primitive. However, the visibility solution computed by a conventional image is far from complete. A conventional image has a uniform sampling rate which can miss visible geometric primitives with a small screen footprint. A conventional …

MULTIPLE STRUCTURE RECOVERY VIA PREFERENCE ANALYSIS IN CONCEPTUAL SPACE
… unstructured visual data in higher level geometric structures is a necessary and basic step to derive better descriptions and understanding of a scene. This challenging problem has a chicken-and-egg pattern: in order to estimate models one needs to first segment the data, and in order to …

The texture shading cache : an approach to asynchronous interactive illumination
… atlas was used as the texture cache, where each geometric primitive in the scene is allocated a space within this atlas during runtime. This solution was then evaluated thoroughly to assess how effective the concept is with respect to both performance and image quality. Multiple modes were …

A fast selective grasping algorithm with deep learning and autonomous dataset creation on point cloud
… RGB images. The proposed algorithm leverages geometric primitive estimation and lateral curvatures to identify optimal grasping regions swiftly and efficiently, where only the object geometry is used to analyze where to grasp. To ensure the selection of desirable objects within the environment …

Estimated Distributed Near-Field Surface Displacements Using Nascent Mobile Laser Scanning
… and models the corresponding point clouds as geometric primitives for change detection. Corresponding point clouds are extracted using PointNet, a deep neural network, and a customized random sample consensus estimator. A combined least squares adjustment is developed for primitive modeling …
