2017 Workshop Spline Approximation and its Applications
2017/11/24
Spline functions are polynomials that are cut into pieces with care. Although spline functions date back to work of Euler and Bernoulli, it was Iso Schoenberg who began to study them in earnest. In la...

2015/6/1
Synthetic Aperture Radar (SAR) images are usually corrupted by a signal-dependent non-additive noise called speckle.
This makes difficult the segmentation, object identification, and feat...
ADAPTIVE TRANSFORMATION OF CARTOGRAPHIC BASES BY MEANS OF MULTIRESOLUTION SPLINE INTERPOLATION
cartography GIS integration algorithms multiresolution vector
2015/6/1
GIS databases often need to include maps from diverse sources. These can differ one another by many characteristics: different projections or reference systems, (slightly) different scales, etc. Theor...

2013/9/9
This paper presents a cubic spline trajectory generation algorithm that produces continuous position, velocity, and acceleration proˉles for 3-axis CNC machines with conˉned axis jerk and tracking err...
Linear system identification using stable spline kernels and PLQ penalties
linear system identification bias-variance trade off kernel-based regularization robust statistics interior point methods piecewise linear quadratic densities
2013/4/27
The classical approach to linear system identification is given by parametric Prediction Error Methods (PEM). In this context, model complexity is often unknown so that a model order selection step is...
