| Boundary tracing | general info regarding boundary tracing. |
| Moore neighborhood | algorithm for finding the raster contour of a binary raster mask.
check out a nice demonstration here: Moore-Neighbor Tracing |
| Chain code | lossless compression of binary raster masks that utilizes contour description/movement to describe the raster mask blob. |
| Prim's algorithm | greedy algorithm for finding minimum spanning tree for a weighted undirected graph. |
| Kalman filter | algorithm for predicting (and interpolating missing) measurements over time.
