On ill-conditioning in 3D Similarity Transformation

International Journal of Environment and Geoinformatics, 2015
3D similarity transformations are often used for datum transformation in Geomatic Engineering. The transformations are routinely performed between the point coordinates evaluated from GNSS (Global Navigation Satellite Systems) observations and the ...

Robust volume assessment of brain tissues for 3-dimensional fourier transformation MRI via a novel multispectral technique.

PLoS ONE, 2015
A new TRIO algorithm method integrating three different algorithms is proposed to perform brain MRI segmentation in the native coordinate space, with no need of transformation to a standard coordinate space or the probability maps for segmentation.
