Image analysis techniques may be employed to identify moving and / or static object within a sequence of spatial data frames (102, 300). Attributes of interest may be identified within a sequence of spatial data frames (102, 300). The attributes of interest may be clustered and examined across frames of the spatial data to detect motion vectors. A system (200) may derive information about these attributes of interest and their motion over time and identify moving and / or static objects, and the moving and / or static objects may be used to generate natural language messages describing the motion of the attributes of interest. Example uses include description of moving and / or static objects in data such as weather data, oil spills, cellular growth (e.g., tumor progression), atmospheric conditions (e.g., the size of a hole in the ozone layer), or any other implementation where it may be desirable to detect motion vectors in a sequence of spatial data frames.

A method of recovering spilled hydrocarbon fluids from a body of water utilizing the increased oleophilic properties of reacted iron particles suspended in a magnetorheological (MR) fluid. The iron particles normally used to create MR fluids, are reacted with an organic compound containing an oleophilic chain end which attaches to the surface of the iron, prior to suspension in a liquid vehicle such as an organic oil. The reacted iron particles in the MR fluid are then applied to and mixed with a hydrocarbon spill on a body of water such as an oil spill, whereby subsequent exposure to a significant magnetic field provides for subsequent recovery of both the reacted magnetic particles and the hydrocarbon spill.
