Real-time Hough Transform Based Circular Shape Extraction

In this paper, two circular shape extraction methods based on C A M (Content Addressable M e m o y ) concept are proposed. The first method based on Hough Transform uses only the gradient amplitude infonnation, while the second uses in addition preselected gradient direction to estimate the center coordinates of the circle and then apply the H T circle extraction to extract i t 's mdius. The ad...

Generalized Hough Transform for Shape Matching

In this paper we propose a novel approach towards shape matching for image retrieval. The system takes advantages of generalized Hough transform, as it works well in detecting arbitrary shapes even in the presence of gaps and in handling rotation, scaling and shift variations, and solves the heavy computational aspect by introducing a preliminary automatic selection of the appropriate contour p...

Real-time object recognition using a modified generalized Hough transform

An approach for real-time object recognition in digital images based on the principle of the generalized Hough transform is proposed. It combines robustness against occlusions, distortions, and noise with invariance under rigid motion and local illumination changes. The computational effort is reduced by employing a novel efficient limitation of the search space in combination with a hierarchic...

High-resolution, real-time three-dimensional shape measurement

Peisen S. Huang, MEMBER SPIE State University of New York at Stony Brook Department of Mechanical Engineering Stony Brook, New York 11794 Abstract. We describe a high-resolution, real-time 3-D shape measurement system based on a digital fringe projection and phase-shifting technique. It utilizes a single-chip digital light processing projector to project computer-generated fringe patterns onto ...

GPU-assisted high-resolution, real-time 3-D shape measurement.

This paper describes a Graphics Processing Unit (GPU)-assisted real-time three-dimensional shape measurement system. Our experiments demonstrated that the absolute coordinates calculation and rendering speed of a GPU is more than four times faster than that of a dual CPU workstation with the same graphics card. By implementing the GPU into our system, we realized simultaneous absolute coordinat...
