Representations of target features (attentional templates) guide attentional object selection during visual search. In many search tasks, targets objects are defined not by a single feature but by the spatial configuration of their component shapes. We used electrophysiological markers of attentional selection processes to determine whether the guidance of shape configuration search is entirely...

In this research, we propose the deformable wavelet template (DWT) for object shape description. DWT o ers not only the global information at the lower scales, but also local features at higher di erential scales. Thus, it provides a natural tool for multiresolution representation and can be used conveniently in a hierarchical matching procedure. In the presentation, we address the three main p...

Kazerooni and Lim report several independent predictors of mortality in new start statin users after long-term follow-up [age, race, number of medications, comorbidities, and body mass index (BMI)]; however, differences in lipid groups and adherence to statin treatment after 1 year were not predictive of long-term mortality in the veteran population studied. This may be due to the low adherence...

In order to perform precise identification and location of artificial coded targets in natural scenes, a novel design of circle-based coded target and the corresponding coarse-fine extraction algorithm are presented. The designed target separates the target box and coding box totally and owns an advantage of rotation invariance. Based on the original target, templates are prepared by three geom...

Recently, shape analysis of human organs has achieved much attention, owing to its potential to localize structural abnormalities. For a group-wise shape analysis, it is important to accurately restore the shape of a target structure in each subject and to build the inter-subject shape correspondences. To accomplish this, we propose a shape modeling method based on the Laplacian deformation fra...

Classification based on shape is central to the problem of discriminating between unexploded ordnance (UXO) and clutter. Most UXO fit a specific profile: they are long and slender with typical length-to-diameter aspect ratios of four or five. Most clutter items, on the other hand, do not fit this profile. Using electromagnetic induction (EMI) sensor data, we present a model-based estimation pro...

Image reconstruction techniques for atmospheric applications often work best with an initial estimate of the object support. This paper examines the ability of a non-imaging laser pointing system to obtain an estimate of target size and shape based on the statistics of the return signal. Fundamental limits on system pointing, such as the tracking errors, corrupt a simple raster scan that would ...

For object extraction, the target object in images often cannot be extracted completely and accurately using only low-level image features, especially from cluttered, occluded and noisy images. In practice, the shape of the target object is often known in advance, and edges can be extracted directly from image, which can contribute to the object extraction task. The authors introduce shape prio...

Statistical shape analysis of brain structures has gained increasing interest from neuroimaging community because it can precisely locate shape differences between healthy and pathological structures. The most difficult and crucial problem is establishing shape correspondence among individual 3D shapes. This paper proposes a new algorithm for 3D shape correspondence. A set of landmarks are samp...

variable rate spray applications using proportional control systems can greatly reduce pesticide use and off-target contamination of environment in orchards. variable rate spraying of the canopy allows growers to apply pesticides only to the target, only use the correct quantity according to canopy size, season and growth stage and to apply plant protection products in an economic and environme...
