Multiple color stripes have been employed for structured light-based rapid range imaging to increase the number of uniquely identifiable stripes. The use of multiple color stripes poses two problems:...
View ArticleRAID: A Relation-Augmented Image Descriptor. (arXiv:1510.01113v1 [cs.GR])
As humans, we regularly interpret images based on the relations between image regions. For example, a person riding object X, or a plank bridging two objects. Current methods provide limited support to...

Existing bidirectional reflectance distribution function (BRDF) models are capable of capturing the distinctive highlights produced by the fibrous nature of wood. However, capturing parameter textures...
View ArticleDense Human Body Correspondences Using Convolutional Networks....
We propose a deep learning approach for finding dense correspondences between 3D scans of people. Our method requires only partial geometric information in the form of two depth maps or partial...
View ArticleImproved visualisation of brain arteriovenous malformations using color...
Color intensity projections (CIPs) have been shown to improve the visualisation of greyscale angiography images by combining greyscale images into a single color image. A key property of the combined...
View ArticleAnti-commutative Dual Complex Numbers and 2D Rigid Transformation....
We introduce a new presentation of the two dimensional rigid transformation which is more concise and efficient than the standard matrix presentation. By modifying the ordinary dual number construction...
