Robust Extraction of Vertices in Range Images by Constraining the Hough Transform
We describe a technique for extracting vertices from range images of cluttered box-like objects. Edge detection is performed and an edge map is acquired. Extraction of vertices is ...

Metrology in uncalibrated images given one vanishing point
In this paper, we describe how 3D Euclidean measurements can be made in a pair of uncalibrated images, when only minimal geometric information are available in the image planes. T...

Achievable Sum-Rate Analysis of Practical Multiuser Scheduling Schemes with Limited Feedback
— We study the performance of fair physical layer schedulers that select a pair of orthogonal users for simultaneous transmission. The schemes rely on partial channel state infor...
