Polynomial Texture Mapping (PTM) uses a simple polynomial regression to interpolate, and hence relight, image sets taken from a fixed camera but with multiple, changing lights with each light illuminating the scene in turn from different directions [1]. PTM is basically an extension of the simple Lambertian model of Photometric Stereo (PST), but replacing a(More)
Polynomial Texture Mapping (PTM) is a technique employed in a variety of settings, from museums to in-the-field image capture to multi-illuminant microscopy. It consists of illuminating the surface in question with lights from a collection of light directions, each light in turn. To date, the most accurate interpolation employed in PTM consists of two(More)
Retention time shift is one of the most challenging problems during the preprocessing of massive chromatographic datasets. Here, an improved version of the moving window fast Fourier transform cross-correlation algorithm is presented to perform nonlinear and robust alignment of chromatograms by analyzing the shifts matrix generated by moving window(More)
