The broader frequency bands between lower airway resonances are thus potentially optimal for the reliable production and accurate percep

Abstract:
Feather mites are among the most abundant and commonly occurring bird ectosymbionts. They live permanently on the host body, are adapted to inhabit well-defined host microhabitats and are found in almost all avian groups. Although feather mites have been extensively studied at the taxonomic level, much diversity remains undescribed and there are many open questions on the biology, ecology and evolution of feather mites. There is also an ongoing debate on the type of symbiosis, that is, whether bird-feather mite interactions are parasitic, commensalistic or even mutualistic. Therefore, better k

Abstract:
We have developed a new Bayesian framework for visual object recognition which is based on the insight that images of objects can be modeled as a conjunction of local features. This framework can be used to both derive an object recognition algorithm and an algorithm for learning the features themselves. The overall approach, called complex feature recognition or CFR, is unique for several reasons: it is broadly applicable to a wide range of object types, it makes constructing object models easy, it is capable of identifying either the class or the identity of an object, and it is

Abstract:
The problem of automatic face recognition is to visually identify a person in an input image. This task is performed by matching the input face against the faces of known people in a database of faces. Most existing work in face recognition has limited the scope of the problem, however, by dealing primarily with frontal views, neutral expressions, and fixed lighting conditions. To help generalize existing face recognition systems, we look at the problem of recognizing faces under a range of viewpoints. In particular, we consider two cases of this problem: (i) many example views ar

Abstract:
Sensory perception entails reliable representation of the external stimuli as impulse activity of individual neurons (i.e. spikes) and neuronal populations in the sensory area. An ongoing challenge in neuroscience is to identify and characterize the features of the stimuli which are relevant to a specific sensory modality and neuronal strategies to effectively and efficiently encode those features. It is widely hypothesized that the neuronal populations employ “sparse coding” strategies to optimize the stimulus representations with a low energetic cost
