A Real-Time Road Sign Detection Using Bilateral Chinese Transform
We present a real-time approach for circular and polygonal road signs detection1 in still images, regardless of their pose and orientation. Object detection is done using a pairwis...

Geometry-Based Automatic Object Localization and 3-D Pose Detection
Given the image of a real-world scene and a polygonal 3-D model of a depicted object, its apparent size, image coordinates, and 3-D orientation are autonomously detected. Based on...

Detection of Point Scatterers by Regularized Inversion of a Linear Ultrasound System Model
Abstract. Scatterer detection in medical ultrasound imaging can be formulated as an inverse problem concerning a linear system model based on point scatterers. The applicability of...

Polygonizing skeletal sheets of CT-scanned objects by partitioin of unity approximations
The skeletal structures of solid objects play an important role in medical and industrial applications. Given a volumetrically sampled solid object, our method extracts a nice-loo...

Computing the visibility graph of points within a polygon
We study the problem of computing the visibility graph defined by a set P of n points inside a polygon Q: two points p, q ∈ P are joined by an edge if the segment pq ⊂ Q. Ef...
