1. An apparatus, comprising: logic, at least a portion of which is in hardware, the logic to: identify respective rotation matrices for each of a plurality of cameras in a heterogeneous camera array and a composite rotation matrix for the heterogeneous camera array; receive a captured image array generated by the heterogeneous camera array; select a rectification process for application to the captured image array; identify a set of rectification maps for the selected rectification process, the set of rectification maps generated based on the respective rotation matrices for the plurality of cameras in the heterogeneous camera array and on the composite rotation matrix for the heterogeneous camera array; and apply the identified set of rectification maps to the captured image array to obtain a rectified image array.
