When using images to locate objects, there is the problem of correcting for distortion and misalignment in the images. An elegant way of solving this problem is to generate an error correcting function that maps points in an image to their corrected locations. We generate such a function by fitting a polynomial to a set of sample points. The objective is to identify a polynomial that passes "sufficiently close" to these points with "good" approximation of intermediate points. In the past, it… 
Correction model based ANN modeling approach for the estimation of radon concentrations in Ohio
According to National Cancer Institute, radon is one of the major causes for lung cancer related deaths after smoking in US. To prevent deaths due to radon inhalation there is a need to determine the


A survey of image registration techniques
This paper organizes this material by establishing the relationship between the variations in the images and the type of registration techniques which can most appropriately be applied, and establishing a framework for understanding the merits and relationships between the wide variety of existing techniques.
Smooth function approximation using neural networks
An algebraic approach for representing multidimensional nonlinear functions by feedforward neural networks is presented and shows that algebraic training is characterized by faster execution speeds and better generalization properties than contemporary optimization techniques.
Density in Approximation Theory
Approximation theory is concerned with the ability to ap- proximate functions by simpler and more easily calculated functions. The first question we ask in approximation theory concerns the
