In this paper, we propose a method for rendering highly detailed close-up views of arbitrary textured surfaces. To augment the texture map locally with high-resolution information, we describe how to automatically, seamlessly merge unregistered images of different scales. Our hierarchical texture representation can easily be rendered in real-time, enabling zooming into specific texture regions ...

[1] The Jurassic Quiet Zone (JQZ) is a region of low-amplitude magnetic anomalies whose distinctive character may be related to geomagnetic field behavior. We collected deep-tow magnetic profiles in Pigafetta Basin (western Pacific) where previous deep-tow data partially covered the JQZ sequence. Our goals were to extend the survey through the JQZ, examine anomaly correlations, and refine a pre...

A method of demosaicing and zooming for color filter array (CFA) via residual image reconstruction is presented. Given the demosaicing and zooming methods, a residual image between the ‘genuine’ image and an initial demosaiced and zoomed image is reconstructed using a dictionary and sparse coding. The ‘genuine’ image has richer edges and details than that of the initially obtained image. A gene...

this paper presents a new observer-based control scheme for a class of nonlinear systems. in the proposed method, nonlinear observer and twisting algorithm controller are employed to realize a sensor-less control strategy for complex systems which makes use of non measurable process information instead of installing as many sensors as possible. due to lack of availability of the complex system ...

Given the wide variety of available classiication algorithms and the volume of data today's organizations need to analyze, the selection of the right algorithm to use on a new problem is an important issue. In this paper we present a combination of techniques to address this problem. The rst one, zooming, analyzes a given dataset and selects relevant (similar) datasets that were processed by th...

This note reports the main research results of the Imaging and Graphic Research Group in the field of image analysis and enhancement. Particular emphasis, reporting also some major details, is given to methods and techniques devoted to unsupervised image analysis and classification, automatic text discrimination, adaptive interpolation and zooming, color and contrast enhancement.

BACKGROUND Adequate young child feeding practices are influenced by a multitude of factors which affect growth and development. A combination of indicators is needed to explain the role of complementary feeding practices in growth retardation. METHODS A cross-sectional nutrition baseline survey was conducted in rural Cambodia in September 2012. Villages in pre-selected communes were randomly ...
