2015/8/19
QuickBird imagery covering Kakamega Forest in Western Kenya and the surrounding farmland (i.e. a total area of 631 km2) has been acquired for the interdisciplinary BIOTA East Africa research project. ...
ADVANCES IN IMAGE PRE-PROCESSING TO IMPROVE AUTOMATED 3D RECONSTRUCTION
Pre-processing Filtering Matching Automation Denoising RGB to Gray Color 3D reconstruction
2015/3/3
Tools and algorithms for automated image processing and 3D reconstruction purposes have become more and more available, giving the possibility to process any dataset of unoriented and markerless image...
Pre-processing of Xeva-XS imagery for determining spectral reflectance coefficients in laboratory conditions
Remote sensing Imagery Accuracy Processing Experiment
2014/12/4
There are two different methodologies which can be used to acquire imagery from which it would be possible to obtain spectral reflectance characteristics – the first based on images of a scene in whic...
Speech Pre-Processing for Pitch and Pitch-Cylce Evolutions Smoothing
Pitch speech coder bit rate pitch cycle
2009/7/28
In low bit rate speech coders, pitch is usually transmitted once per frame and, when needed, the intermediate pitch values are obtained by interpolation between 2 adjacent pitch values. Although pitch...
