Particle Image Velocimetry (PIV) and optical flow methods represent two cornerstone approaches in experimental fluid dynamics and motion estimation. PIV employs tracer particles seeded in a fluid, ...

The cover of the Dec. 4 issue of Current Biology features breakthrough research in optic flow conducted by William Warren, professor and chair of the department of cognitive and linguistic sciences.

Computer scientists have written a network flow algorithm that computes almost as fast as is mathematically possible. This algorithm computes the maximum traffic flow with minimum transport costs for ...
