1. An apparatus for optical flow estimation, the apparatus comprising:
a memory configured to store data corresponding to one or more frames; and
a processor coupled to the memory and configured to:
perform object detection on at least one feature associated with a first frame to determine an object type associated with the at least one feature;
determine an optical flow prediction associated with a plurality of frames based on the object type associated with the at least one feature;
determine a position of the at least one feature associated with the first frame;
determine, based on the position of the at least one feature in the first frame and the optical flow prediction, a position estimate of a search area for searching for the at least one feature in a second frame; and
determine, from within the search area, a position of the at least one feature in the second frame.
