A Novel Feature Descriptor Invariant to Complex Brightness Changes
We describe a novel and robust feature descriptor called ordinal spatial intensity distribution (OSID) which is invariant to any monotonically increasing brightness changes. Many t...

Complex Spatio-Temporal Pattern Queries
This paper introduces a novel type of query, what we name Spatio-temporal Pattern Queries (STP). Such a query specifies a spatiotemporal pattern as a sequence of distinct spatial...

Spatial-Temporal Fusion for High Accuracy Depth Maps Using Dynamic MRFs
— Time-of-flight range sensors and passive stereo have complimentary characteristics in nature. To fuse them to get high accuracy depth maps varying over time, we extend traditi...

The mqr-tree: Improving upon a 2-dimensional spatial access method
We propose the mqr-tree, a two-dimensional spatial access method that improves upon the 2DR-tree. The 2DRtree uses two-dimensional nodes so that the relationships between all obje...
