Dbexpress Unidirectional Datasets

Conversations on the Internet are often disjointed and unidirectional. In many cases, conversations are occuring in many different places on the same topic. The SpaceMapper effort was born from the classic Internet desire to see if there is a better way.

A library of tools and API (C++ and Python) for the storage and processing of large 3D laser scanning (LiDAR, ALS, TLS) datasets using a pulse based spatially indexed file format (SPD) which support for both discrete return and full waveform datasets

Teem is a coordinated group of libraries for representing, processing, and visualizing scientific raster data. Teem includes command-line tools that permit the library functions to be quickly applied to files and streams, without having to write any code. The most important and useful libraries...

Chronoscope is a visualization platform under development at Timepedia for time series datasets. Chronoscope stems from a desire for responsiveness and interactivity when navigating or authoring datasets. Features:- Support for very large datasets (~20,000 points) - Multiresolution representation...

ZedGraph is a set of classes for creating 2D line and bar graphs of arbitrary datasets. The classes provide a high degree of flexibility -- almost every aspect of the graph can be user-modified. At the same time, usage of the classes is kept simple by providing default values for all of the graph...

Run "parrecreader.m"This program reads the native PAR/REC files, imports them to Matlab workspace and displays them.This is a stripped down version of code developed for MR Elastography purposes, but should be useful for other applications as well.Two sample datasets are included: i)T2W anatomy...

Only in very simple situations can we describe the correlation between two time series as a single number. Often it varies both as a function of time, and of wavelength. Datasets may be uncorrelated on short timescales due to noise, but strongly correlated on larger wavelengths (eg annual).This...

This method computes an accurate continuous approximation of the DW-MRI signal using adaptive kernels (A. Barmpoutis et al. "Adaptive kernels for multi-fiber reconstruction", In the Proceedings of IPMI, 2009). The approximation is based on Fig. 3 of the article which shows the plot of the DW-MRI...

This is an implementation of part of Kanan & Cottrell (2010), which extracts dense features from color images which can then be used for object or face classification. In our experiments they perform quite well, generally about as well as SIFT descriptors, if not better, on a variety of popular...

Fitting a t-copula using the method of moments described in Quantitative Risk Management by McNeil, Frey and Embrechts. The outputs from this function correspond to those of the statistics toolbox's copulafit('t',u) . For large datasets, tcopulafit is immeasurably faster than copulafit('t',u)....
