Dear all,<br><br>I'm working on fcMRI processing, and need polynomial fitting (3rd order, ax^3 + bx^2 + cx +d) for each time course (with about 600 time points) to remove B0 fluctuation or shifting. The entire data set has 128 * 128 * 7 samples (
i.e. time courses).<br><br>The questions are:<br>1. Is there such an algorithm in ITK (including vnl/vcl)?<br> 2. If so, for fast processing of 1-D signal with 600 samples, what are be best choices?<br><br>I appreciate the help!
