Image Classification Using Spatial Pyramid Coding and Visual Word Reweighting
The ignorance on spatial information and semantics of visual words becomes main obstacles in the bag-of-visual-words (BoW) method for image classification. To address the obstacles...

Image Retrieval with Geometry-Preserving Visual Phrases
The most popular approach to large scale image retrieval is based on the bag-of-visual-word (BoV) representation of images. The spatial information is usually reintroduced as a po...

Multi-robot plan adaptation by constrained minimal distortion feature mapping
We propose a novel method for multi-robot plan adaptation which can be used for adapting existing spatial plans of robotic teams to new environments or imitating collaborative spat...

Enhancing the Accessibility of Maps with Personal Frames of Reference
Abstract. The visualization of geographic information requires large displays. Even large screens can be insufficient to visualize e.g. a long route in a scale, such that all decis...

Dynamics and Function of a CA1 Model of the Hippocampus during Theta and Ripples
The hippocampus is known to be involved in spatial learning in rats. Spatial learning involves the encoding and replay of temporally sequenced spatial information. Temporally seque...

Spatial pattern growth and emergent animat segregation
Spatial agent models can be used to explore self-organising effects such as pattern growth and segregation. We employ our predator-prey model to study these emergent behaviours in...

Verbally Annotated Tactile Maps - Challenges and Approaches
Survey knowledge of spatial environments can be successfully conveyed by visual maps. For visually impaired people, tactile maps have been proposed as a substitute. The latter are ...
