Ears are an emergent biometric accruing application advantages including no requirement for subject contact and acquisition without demand. To recognize a subject's ear, we aim to extract a characteristic vector from a human ear image that may subsequently be used to identify or confirm the identity of the owner. Towards this end, a novel force field(More)
OBJECTIVE To evaluate the therapeutic effects of selective cholinergic replacement with xanomeline tartrate, an m1 and m4 selective muscarinic receptor (mAChR) agonist in patients with probable Alzheimer disease (AD). DESIGN A 6-month, randomized, double-blind, placebo-controlled, parallel-group trial followed by a 1-month, single-blind, placebo washout.(More)
The objective in defining feature space is to reduce the dimension of the original pattem space yet maintaining discriminatory power for classijkation [l]. To meet this objective in the context of ear and face biometrics a novel force field transformation has been developed in which the image is treated as an array of Gaussian attractors that act as the(More)
Children are often the unintended or indirect victims of wife abuse as witnesses of this violence in their family. Current research on these children and a conceptual framework to understand how this violence affects their development are outlined. The implications of this research are discussed in terms of several intervention strategies. The importance of(More)
There is a rich literature of approaches to image feature extraction in computer vision. Many sophisticated approaches exist for low-and high-level feature extraction but can be complex to implement with parameter choice guided by experimentation, but impeded by speed of computation. We have developed new ways to extract features based on notional use of(More)
The overall objective in de®ning feature space is to reduce the dimensionality of pattern space yet maintaining discriminatory power for classi®cation and invariant description. To meet this objective, in the context of ear biometrics, a novel force ®eld transformation has been developed in which the image is treated as an array of Gaussian attractors that(More)
This paper discusses the clinical implications of our current knowledge about children exposed to violence. It highlights a number of typical case scenarios in which mental health professionals have responded inadequately to the issue of violence. Alternative strategies for assessing and treating children exposed to violence are offered which have both(More)
