Scale-Cascaded Coalescence

A method for generating a coalesced image includes receiving a plurality of fields for a geographical region. A set of forces is determined for each of the fields by multiplying a gradient of a respective one of the fields with a difference between the respective one of the fields and each of the other fields. A net influence for each field is determined by averaging each of the forces associated with the respective field. A spectral filter is applied to each net influence to generate a respective value of a mode of motion used to deform each field and then displace each field until each field coalesces with each other field.
