ICCV Challenge Contest: Where Am I?


This contest was held at the International Conference of Computer Vision, 2005. Given a set of images taken at known GPS locations, the problem was to find GPS locations of test images taken at unknown locations but roughly in the same area (view overlap). Our team consisted of five researchers including myself. We received an honorable mention at the conference for achieving fourth place amongst twenty participating teams from top universities all over the world.

Figure 1: The figure demonstrates the basic task. Given a set of images taken at known GPS locations (a), we had to find the GPS locations of un-labeled pictures (b).
