Abstract
This dissertation presents a collection of visualization techniques that highlight features (i.e, certain visual aspects that are interesting to the viewers, such as sharp corners on a boundary). These include three Marching Squares extensions: (1) Sharp Corner Sensitive Marching Squares (SCS-MS) that recovers sharp corner features in isocontours, (2) Dual Marching Squares (DMS) that recovers curved features in isocontours and (3) Fine Feature Sensitive Marching Squares (FFS-MS) that recovers small and narrow areas enclosed by boundaries. Also included is a novel motion visualization technique that generates speedlines that mimick the speedline style of Manga artist Osamu Tezuka. Experimental results and analyses of the techniques are also presented.
