This paper builds on prior research demonstrating this effect and proposes a simpler explanation for it: that people easily conflate relative with absolute evaluation, especially on ambiguous measures of evaluation. The paper then presents a series of four studies that examine this conflation expl...

Making Good Features Track Better

This paper addresses robust feature tracking. We extend the well-known Shi-Tomasi-Kanade tracker by introducing an automatic scheme for rejecting spurious features. We employ a simple and efficient outlier rejection rule, called X84, and prove that its theoretical assumptions are satisfied in the feature tracking scenario. Experiments with real and synthetic images confirm that our algorithm ma...
