<p>Update from Wiki</p> <p><b>New page</b></p><div>== Automated mosaicking and feature tracking in Electron Microscopy data ==<br /> <br /> [[Image:2006_AHM_Programming_Half_Week_EMAutomatedMosaicingAndTracking.ppt|Link to powerpoint summary]]<br /> <br /> ==== Goals ====<br /> <br /> # Develop a set of tools for automated assembly of electron microscopy mosaic composed of hundreds of high resolution (4000x4000) image tiles.<br /> # Develop a set of tools for automated registration of assembled mosaics (slices) into a volume.<br /> # Develop an application for user-guided feature tracking and annotation within a volume.<br /> <br /> ==== Current Status ====<br /> <br /> # The prototype mosaicking toolkit has been successfully tested on automated assembly of a mosaic of 12 high resolution (3000x4000) EM images.<br /> <br /> ==== Current Tools ====<br /> <br /> # Automated image cropper used to correct for rotation errors and to remove image borders (relies on strong assumptions on image structure).<br /> # Fast mosaic layout estimator using correlation in the Fourier domain.<br /> # Mosaic refinement tool used to correct for optical and mechanical warping in the mosaic image tiles via a 2D bivariate polynomial transform.<br /> # A tool for assembling a mosaic for viewing from a set of images and corresponding transforms.<br /> <br /> ==== Team Members ====<br /> <br /> * Tolga Tasdizen - University of Utah<br /> * Liz Jurrus - University of Utah<br /> * Paul Koshevoy - University of Utah</div>
