Fast, Illumination Insensitive Face Detection Based on Multilinear Techniques and Curvature Features
14 years 5 months ago
This paper brings together two recent developments in image analysis. We consider a new mathematical framework that provides illumination invariant descriptors for face detection....

Higher order spatial features, such as doublets or
triplets have been used to incorporate spatial information
into the bag-of-local-features model. Due to computational
limits, ...
