Android Insecurity, Clear Photos, Speech to Emotion, and Microexpressions from Video

  1. 87% of Android Devices Insecure — researchers find they’re vulnerable to malicious apps because manufacturers have not provided regular security updates. (via Bruce Schneier)
  2. A Computational Approach for Obstruction-Free Photography (Google Research) — take multiple photos from different angles through occlusions like a window with raindrops or reflections, and their software will assemble an unoccluded image. (via Greg Linden)
  3. Algorithms for Affective SensingResults show that the system achieves a six-emotion decision-level correct classification rate of 80% for an acted dataset with clean speech. This PhD thesis is research into algorithm for determining emotion from speech samples, which does so more accurately than humans in a controlled test. (via New Scientist)
  4. Software Learns to Recognise Microexpressions (MIT Technology Review) — Li and co’s machine matched human ability to spot and recognize microexpressions and significantly outperformed humans at the recognition task alone.
