Spatial-temporal-structure processor for multi-sensor, multi scan data fusion

摘要

A system is provided for associating a set of data values where each data value belongs to one of a plurality of classes and also to one of a plurality of types. The system includes an array of memory cells arranged in rows and columns, each memory cell storing one data value. An energy computation cell for each column is coupled for computing an energy value proportional to the likelihood that the data values in each column comprise one of the desired associations. A system control module to the energy computation cells for transferring the data values of a given class and type from one memory cell to another memory cell of the same class and type, within a given row of memory cells when the replacement lowers to the energy value for the column. The energy values computed by all the energy computation cells are summed to determine a total energy value. Each time data values are transferred, the total energy value of all of the energy cells is computed. The lowest total energy value after successive replacements represents a state in which each column contains the desired association of data values.
