The appearance of individuals captured by multiple non-overlapping cameras varies greatly due to pose and illumination changes between camera views. In this paper we address the problem of dealing with illumination changes in order to recover matching of individuals appearing at different camera sites. This task is challenging as accurately mapping colour changes between views requires an exhau...

In this paper we study the following question related to Diophantine approximations and geometric measure theory: for a given set Ω find α such that α−θ has bad Diophantine properties simultaneously for all θ ∈ Ω. How do the arising Diophantine inequalities depend on the geometry of the set Ω? We provide several methods which yield different answers in terms of the metric entropy of Ω and consi...

This paper describes a method of retrieving handwritten text using directional features. Text search from handwritten digital ink employing character recognition technology has been developed. However, the character recognition based approach does not support languages which are not assumed. To address this problem, the proposed method was devised to hypothetically segment text into character s...

Many field measurements of viability and sexual selection on body size indicate that large size is favoured. However, life-history theory predicts that body size may be optimized and that patterns of selection may often be stabilizing rather than directional. One reason for this discrepancy may be that field estimates of selection tend to focus on limited components of fitness and may not fully...

The objective of this paper is to provide a comprehensive efficiency measures to estimate the performances of OECD and non-OECD countries. A Russell directional distance function that appropriately credits the decision making unit not only for increase in desirable outputs but also for the decrease of undesirable outputs is derived from the proposed weighted Russell directional distance model. ...

In this paper we present a lossy image coder based in multiscale and directional contourlet transform which allows edge preserving in decompressed images. The preserving task is made by capture the edge points of an image using a robust and efficient edge detector known as Smallest Univalue Segment Assimilating Nucleus (SUSAN). The resulting edges coordinates are used as a priori knowledge of t...

A multi-transmitting boundary is a local artificial widely used for numerically simulating seismic site effects. However, similar to other boundaries, the has instability issue in numerical simulation. Based on concept of multi-directional transmitting formula, strategy eliminating high-frequency studied and measure proposed using neighbour node realize smoothing filtering. The verified through...

In this paper, we present a novel approach for the segmentation of white matter tracts based on Finsler active contours. This technique provides an optimal measure of connectivity, explicitly segments the connecting fiber bundle, and is equipped with a metric which is able to utilize the directional information of high angular resolution data. We demonstrate the effectiveness of the algorithm f...

Various technologies have been used to measure airway flow for human respiration. This paper presents a flow sensor (pneumotach} that is capable of continuous, bi-directional airway flow measurement proximal to the patient and used in a critical care environment. This paper presents some of the findings of the research that was done in the development of a n~w flow sensor for long term flow mon...

We give error estimates for the approximation of a laminated microstructure which minimizes the energy R (rv(x))dx for a rotationally invariant, double well energy density (A). We present error estimates for the convergence of the deformation in L; the convergence of directional derivatives of the deformation in the \twin planes," the weak convergence of the deformation gradient, the convergenc...
