Quaddles: A multidimensional 3-D object set with parametrically controlled and customizable features

3-D controlled source electromagnetic interferometry by multidimensional deconvolution

Controlled Source Electromagnetic (CSEM) is an important technique in hydrocarbon exploration, because it uses the large contrast in electrical resistivity to distinguishes between water and hydrocarbons. In a shallow sea environment, the airwave that is refracted from the air-water interface dominates the recorded signal at large offsets. Therefore, the hydrocarbon detection ability of the CSE...

Improved Appearance-Based 3-D Object Recognition Using Wavelet Features

In this paper we present an improved appearancebased approach for the localization and classification of 3-D objects in 2-D gray level images. Thereby we calculate local feature vectors by the coefficients of the wavelet multiresolution analysis and model them statistically. Since the appearance of the objects, i. e. also the size of the objects in the image, vary due to out-of-image-plane tran...

A Model-Based 3-D Object Recognition System using Geometric Hashing with Attributed Features

We build an object recognition system that is able to recognize 3-D objects such as vehicles embedded in highly complicated backgrounds. We use the geometric hashing method, augmenting the approach through the use of attributed features, k-d trees for access to features, and the use of bounds in order to limit the search. We make use of expressive features to improve the performance of a geomet...

Customizable Object Recovery Pattern

In this paper a design pattern for Object Recovery is described. The Customizable Object Recovery pattern defines a generic object recovery algorithm. It decouples the recovery part from the object’s functional part. Different policies can be supported: update-in-place, deferred-update, copy and compensating. The Customizable Object Recovery pattern isolates recovery from persistence and object...
