Thin-plate spline analysis of shape differences between a primitive and modern rhinoceros

Thin-plate spline analysis of mandibular growth.

The analysis of mandibular growth changes around the pubertal spurt in humans has several important implications for the diagnosis and orthopedic correction of skeletal disharmonies. The purpose of this study was to evaluate mandibular shape and size growth changes around the pubertal spurt in a longitudinal sample of subjects with normal occlusion by means of an appropriate morphometric techni...

Approximate Thin Plate Spline Mappings

The thin plate spline (TPS) is an e ective tool for modeling coordinate transformations that has been applied successfully in several computer vision applications. Unfortunately the solution requires the inversion of a p p matrix, where p is the number of points in the data set, thus making it impractical for large scale applications. As it turns out, a surprisingly good approximate solution is...

Illumination Estimation via Thin-Plate Spline Interpolation

Thin-plate spline interpolation is used to interpolate the chromaticity of the color of the incident scene illumination across a training set of images. Given the image of a scene under unknown illumination, the chromaticity of the scene illumination can be found from the interpolated function. The resulting illumination-estimation method can be used to provide color constancy under changing il...

Thin Plate Spline Approximation for Image Registration

The point based registration technique of Book stein can be seen as an interpolation problem With this technique an elastic transformation based on thin plate splines is determinedwhich maps the source and target land marks exactly to each other However in real applications the positions of the landmarks can only be determined ap proximately Therefore in this case an interpolation scheme is ina...
