Laser speckle photography for surface tampering detection
It is often desirable to detect whether a surface has been touched, even when the changes made to that surface are too subtle to see in a pair of before and after images. To addre...

Illumination Normalization Using Logarithm Transforms for Face Authentication
Abstract. In this paper we propose an algorithm that can easily be implemented on small form factor devices to perform illumination normalization in face images captured under vari...

Multi view registration for novelty/background separation
We propose a system for the automatic segmentation of novelties from the background in scenarios where multiple images of the same environment are available e.g. obtained by weara...

Illumination transfer using homomorphic wavelet filtering and its application to light-insensitive face recognition
In this paper, we propose a novel homomorphic wavelet filtering based illumination transfer technique to change the dominant lighting of one face image (source face image) to anot...
