Marginal bone changes around titanium plasma-sprayed implants (n = 240) placed in the mandibular interforaminal regions of 120 edentulous patients were assessed over 5 years of follow-up, with emphasis on the influence of the locations of the microgap and rough/smooth border. Marginal bone changes were measured on standardized radiographs. Locations of the microgap and the rough/smooth border w...

Efficiency Comparative Graph Model can benefit from improved efficiency by reducing the amount of comparisons computed. If features all belonged to specific regions, regions can be compared to the same regions across other images. This would reduce the amount of computation significantly. To ensure features near the border of regions are not missed, a region can be compared to the same region p...

This paper presents a new segmentation and coding algorithm for nonbinary images. The algorithm performs contour coding of regions of equally valued and connected pixels. It consists of two distinct phases: raster scanning and border following. I n this sense it is similar to algorithms presented by Kruse. However, the algorithm of this paper is considerably improved since it correctly segments...

A basic result of new economic geography (NEG) models is that the proximity to consumer markets impacts wages and employment within regions. The ongoing process of European integration, being targeted on the reduction of barriers to trade and factor mobility, has presumably changed relative market access in Europe. The present paper aims at providing some evidence on spatial effects of integrat...

This paper introduces a multiresolution image segmentation algorithm for scalable object-based wavelet coding applications. This algorithm is based on discrete wavelet transform and multiresolution Markov random field (MMRF) modelling. The major contribution of this work is to add spatial scalability and border smoothness in the segmentation algorithm usable for object-based wavelet coding algo...

The Café Wall illusion (seen on the tiles of a local café) is a Münsterberg chequerboard figure, but with horizontal parallel lines which may have any luminance separating the rows of displaced squares. These (the 'mortar' lines) display marked wedge distortion which is especially affected by: contrast of the squares ('tiles'); width of the 'mortar' lines, and their luminance which must not be ...
