Britain's National Portrait Gallery, which has recently acquired a striking new wing, has this autumn also obtained a very new kind of portrait. Artist Marc Quinn has created a 'genomic portrait' of Sir John Sulston, former director of the Wellcome Trust's Sanger Centre near Cambridge, who led the UK arm of the human genome project which announced completion of the first draft last year. As the...

The art gallery problem is to determine the number of guards that are sufficient to cover or see every point in the interior of an art gallery. An art gallery can be viewed as a polygon P with or without holes with a total of n vertices and guards as points in P . Any point z ∈ P is said to be visible from a guard g if the line segment joining z and g does not intersect the exterior of P . Usua...

We experimentally demonstrate continuous-wave ultraviolet emission through forth-harmonic generation in a millimeter-scale lithium niobate whispering-gallery resonator pumped with a telecommunication-compatible infrared source. The whispering-gallery resonator provides four spectral lines at ultraviolet, visible, near-infrared and infrared, which are equally spaced in frequency via the cascaded...

Dynamic Link Matching is a neural dynamics for translation invariant object recognition that is robust against distortion. We here demonstrate human face recognition against a gallery of 112 neutral frontal view faces. Probe images are distorted due to rotation in depth and changing facial expression. Probe images and gallery models are represented by layers of neurons interpreted as labeled gr...

We consider the problem of guarding galleries that have no small nooks (regions that are visible from only a small fraction of the entire gallery). Intuitively, such galleries (of which convex galleries are a special but uninteresting case) should need fewer guards. We show that in any simply connected gallery in which every corner sees at least a fraction of the other corners there exist a set...

Aesthetic judgments, like most judgments, depend on context. Whether an object or image is seen in daily life or in an art gallery can significantly modulate the aesthetic value humans attach to it. We investigated the neural system supporting this modulation by presenting human subjects with artworks under different contexts whilst acquiring fMRI data. Using the same database of artworks, we r...

This paper presents an updated technical overview of an integrated content and metadata-based image retrieval system used by several major art galleries in Europe including the Louvre in Paris, the Victoria and Albert Museum in London, the Uffizi Gallery in Florence and the National Gallery in London. In our approach, the subjects of a query (e.g. images, textual metadata attributes), the opera...

The Albert H. Nahmad Panama Canal Gallery opened to the public in 2017 as a venue for exhibitions on history of featuring objects from Museum Collection (PCMC). This article discusses physical space, exhibit cases, exhibition schedule, and unique features Gallery.

We present a structural matching technique for robust classification based on image sets. In set based classification, a probe set is matched with a number of gallery sets and assigned the label of the most similar set. We represent each image set by a sparse dictionary and compute a similarity matrix by matching all the dictionary atoms of the gallery and probe sets. The similarity matrix comp...

Results are presented for the largest experimental study to date that investigates the comparison and combination of 2D and 3D face data for biometric recognition. To our knowledge, this is also the only such study to incorporate significant time lapse between gallery and probe image acquisition. Recognition results are presented for gallery and probe datasets of 166 subjects imaged in both 2D ...
