An array of magnetic variometers has been operated in the south-east corner of the Australian mainland, observing the coast effect simultaneously in two dimensions for the first time. The observations are presented as sets of variograms in the time domain and as contour maps of certain parameters in the frequency domain. Vertical field response functions are determined for each station, and the...

We present an efficient multi stage approach to detection of deformable objects in real, cluttered images given a single or few hand drawn examples as models. The method handles deformations of the object by first breaking the given model into segments at high curvature points. We allow bending at these points as it has been studied that deformation typically happens at high curvature points. T...

in order to determine optimum landuses (in accordance with natural capability) and improve the current land management, landuse planning process was applied by using gis. within the framework of system analysis approach basic ecological and socio-economic , data were mapped. the mapped data were digitized and imported to idrisi and arc/info to build a database ,along with other descriptive data...

Topographic maps represent the delineation of features of interest in a terrain by means of contour lines. There are several benefits of maintaining topographic maps in sensor networks they can be used for resolving spatial queries, visualizing available resources in the network, and understanding spatio-temporal characteristics about the events being monitored. In this paper, we consider the p...

The goal of stereo algorithms is to determine the threedimensional distance, or depth, of objects from a stereo pair of images. The usual approach is to first identify corresponding features between the two images and estimate their depths, then interpolate to obtain a complete distance or depth map. Traditionally, finding the corresponding features has been considered to be the most difficult ...

Self-organizing maps (SOMs, Kohonen, 1982) have been extensively used as information processing models in music perception. Using a corpus that represents tonal regularities in Western music, Tillmann et.al (2000) developed a schema of Western tonal music. Krumhansl, et.al (2000) showed that melodic expectancy in Finnish music could be modeled by SOMs trained on samples of Finnish music. Recent...

High-resolution TEM is well-suited to characterizing nanocrystals, where lattice fringes serve as a source of structural information [1, 2]. For example, 3D lattice parameters can be measured from 2D lattice fringe images taken at as few as two different specimen orientations [3-6]. Recent work has shown that lattice fringe-visibility maps, a thin-specimen extension of bend-contour and channeli...

Modern object detectors are vulnerable to adversarial examples, which may bring risks real-world applications. The sparse attack is an important task which, compared with the popular perturbation on whole image, needs select potential pixels that generally regularized by ℓ0-norm constraint, and simultaneously optimize corresponding texture. non-differentiability of ℓ0 norm brings challenges man...

Keypoints (junctions) provide important information for focus-of-attention (FoA) and object categorization/recognition. In this paper we analyze the multi-scale keypoint representation, obtained by applying a linear and quasi-continuous scaling to an optimized model of cortical end-stopped cells, in order to study its importance and possibilities for developing a visual, cortical architecture. ...
