Illumination Intensity, Object Geometry and Highlights Invariance in Multispectral Imaging
It is well-known that image pixel values of an object could vary if the lighting conditions change. Some common factors that produce changes in the pixels values are due to the vie...

Computational Geometry of Contour Extraction
We present a method for extracting contours from digital images using techniques from computational geometry. Our approach is different from traditional pixelbased methods in imag...

Frontal geometry from sketches of engineering objects: is line labelling necessary?
A tool which can quickly interpret line drawings (with hidden lines removed) of engineering objects as boundary representation CAD models would be of significant benefit in the pr...

Efficient Tracking of Regular Patterns on Non-Rigid Geometry
We introduce a real-time robust tracking procedure for a regular pattern marked on a flexible moving surface such as cloth. Our system is capable of maintaining the tracked grid s...
