Real-time 3D semi-local surface patch extraction using GPGPU

Real-time 3D semi-local surface patch extraction using GPGPU: Application to 3D object recognition

Feature vectors can be anything from simple surface normals to more complex feature descriptors. Feature extraction is important in order to solve various computer vision problems: e.g. registration, object recognition and scene understanding. Most of these techniques cannot be computed online due to their complexity and the context where they are applied. Therefore computing these features in ...

Detection of Congenital Mullerian Anomalies Using Real-Time 3D Sonography

Automated Surface Extraction in Real Time Photogrammetry

Considerable research attention has been given to close-range videometric systems for vision-based, three-dimensional object measurement over recent years. These systems have to demonstrate high speed, high accuracy capability and high flexibility to compete as a three-dimensional coordinate measurement tool. Especially in industries where instant feedback is required, such as production line o...

Real-time 3D Feature Extraction without Explicit 3D Object Reconstruction

For the communication between human and computer in an interactive computing environment, the gesture recognition is studied vigorously. Therefore, a lot of studies have proposed efficient methods about the recognition algorithm using 2D camera captured images. However, there is a limitation to these methods, such as the extracted features cannot fully represent the object in real world. Althou...

3D planar patch extraction from stereo using probabilistic region growing

This article presents a novel 3D planar patch extraction method using a probabilistic region growing algorithm. Our method works by simultaneously initiating multiple planar patches from seed points, the latter determined by an intensity-based 2D segmentation algorithm in the stereopair images. The patches are grown incrementally and in parallel as 3D scene points are considered for membership,...
