Visual Berrypicking (2014)


This is joint work together with Thomas Low and Christian Hentschel who are supervised by Andreas N├╝rnberger and Harald Sack, respectively. The demo video was created by Thomas Low.

Challenge

With increasing collection size and complexity of the similarity metric, projection accuracy rapidly degrades and computational costs prevent online map generation.

Solution

Create the impression of panning a large (global) map by aligning inexpensive small maps showing local neighborhoods.

Core Technologies

  • local map generation: multidimensional scaling (MDS)
  • map alignment: Procrustes analysis
  • backend implementation: Python, Java
  • frontend implementation: HTML5 (jQuery)
