To combine social and content-based ltering techniques for image data, we have developed a new approach that uses clustering of images based on both content and social information. In this paper, we propose a visual interface that makes use of this clustering technique to explain the ltering results. The items in the database are laid out on a 2 dimensional map according to content-based simila...

A lot of research has been conducted on 3D surface reconstruction using multiple images of fixed view point and varying lighting conditions. In this paper, a new image-based modeling technique based on Polynomial Texture Mapping (PTM) is presented. This technique allows automated reconstruction of highly detailed 3D texture-mapped models. The new technique addresses some of the shortcomings of ...

Geospatial data are often visualized as 2D cartographic maps with interactive display of detail on-demand. Integration of the 2D map, which represents high level information, with the details pertaining to specific locations is a key design issue in geovisualization. Solutions include multiple linked displays around the map which can impose cognitive load on the user as the number of links goes...

A bounded linear operator that maps H to L and L to L is bounded from L to L for each p ∈ (1, 2), by a famous interpolation result of Fefferman and Stein. We prove L-norm bounds that grow like O ( 1/(p− 1) ) as p ↓ 1. This growth rate is optimal, and improves significantly on the previously known exponential bound O(21/(p−1)).

Until now, Universal Kriging has not been used for the mapping of geological data in Croatia. However, it is one of the most frequently used methods of Kriging, probably the most adequate in cases when the input data is marked by a common trend. That exact feature is often an attribute of deep geological data, and thereby that of structural maps. Mapped surfaces in a row of examples have a stru...

We present a technique for blending multiple images of an object into a single, view-dependent texture map for that object. This technique can be used for image-based rendering, when the object is known, or for “painting” a view-dependent texture map of an object. The technique provides a structured mechanism for combining images at different resolutions, producing a mip-map like structure with...

In this paper, a novel technique of online incremental speaker adaptation for speech stream separation in telemedicine is proposed. An unsupervised discriminative linear regression technique is developed based on the principle of maximizing the class separation margin to transform model mean. This adaptation approach is called largest margin linear regression (LMLR). Online incremental LMLR and...

Both sensor calibration and satellite retrieval algorithm play an important role in the ability to determine accurately long-term trends from satellite data. Owing to the unprecedented accuracy and long-term stability of its radiometric calibration, SeaWiFS measurements exhibit minimal uncertainty with respect to sensor calibration. In this study, we take advantage of this well-calibrated set o...

Smoothed data maps permit the reader to identify general spatial trends by removing the background noise of random variability often present in raw data. To smooth mortality data from 798 small areas comprising the contiguous United States, we extended the head-banging algorithm to allow for differential weighting of the values to be smoothed. Actual and simulated data sets were used to determi...
