The issue of graphic map load is currently very often overlooked. Conversely, having an objective knowledge the level a helps cartographers to assume map’s readability and suitability for target group users. aim this study is, therefore, use Graphic Map Load Measuring Tool (GMLMT) Subband Entropy script as metrics evaluate influence terrain type (plains, hills, highlands, mountains, high mounta...

A subtask of voice conversion is to accurately map the pitch contour of a source speaker to a target speaker. So far, the most widely employed method for carrying out this mapping is based on adjusting the pitch range of the source speaker to match the target while keeping the shape of the contour unchanged. In this project, we investigate four alternative algorithms for pitch contour mapping a...

Keywords: Noise mapping Grid refinement Uncertainty Interpolation GIS Noise maps are usually represented as contour or isolines maps describing the sound levels in a region. Using this kind of representation the user can easily find the noise level assigned to every location in the map. But the acoustic calculations behind the map are not performed for every single location on it; they are only...

In situ measurements of ion densities and temperatures have been analyzed to produce profiles of these plasma parameters along the Voyager 1 inbound trajectory between 7 and 5 R j. The temperature profile shows a sharp decrease by a factor of •,,50 between 5.8 and 5.2Rj corresponding to a temperature gradient of •,7 x l0 s per R r The electron density profile, inferred from the ion density meas...

The use of visual information from lip movements can improve the accuracy and robustness of a speech recognition system. Accurate extraction of visual features associated with the lips is thus very important. In this paper, we present a deformable model-based technique for lip contour extraction from color lip images. The geometric lip model we proposed is able to fit different lip shapes. Our ...

We introduce a method that uses contour fragments to highlight regions of interest. Our method obtains as input either a binary image or the gradient map of a gray-level image. It produces a saliency map that re0ects for every point in the image our belief that it belongs to a salient region. Saliency is determined by criteria such as closure, convexity, and size. In addition, gaps in the bound...

A challenge when using current magnetic resonance (MR)-based attenuation correction in positron emission tomography/MR imaging (PET/MRI) is that the MRIs can have a signal void around the dental fillings that is segmented as artificial air-regions in the attenuation map. For artifacts connected to the background, we propose an extension to an existing active contour algorithm to delineate the o...

A novel method is proposed to detect multi-part objects of unknown specific shape and appearance in natural images. It consists in first extracting a strictly oversegmented map of circular arcs and straight-line segments from an edge map. Each obtained constant-curvature contour primitive has an unknown origin which may be the external boundary of an interesting object, the textured or marked r...

A method is proposed to enhance boundary primitives of multi-part objects of unknown specific shape and appearance in natural images. Its input is a strictly over-segmented constant-curvature contour primitive (CCP) map. Each circular arc or straight-line segment primitive from the map has an unknown origin which may be the closed boundary of a multi-part object, the textured or marked region e...

We propose a system to perform disparity estimation for a pair of stereo images using object-based global constraints. EEective global constraints are crucial to accurate disparity estimation under the presence of partially occluded areas, illumination diierences, and object deformation. In our method, object contours are rst extracted and their disparities are estimated using a robust tree mat...
