Abstract
Systems and methods may provide for identifying a plurality of areas in an image frame, and using fixed functionality logic to determine phase information for the image frame on an area-by-area basis. Additionally, a programmable processor can be used to identify motion associated with the image frame based at least in part on the phase information.
Claims27
A system comprising:
- a camera to capture an image frame;
- a programmable processor;
- memory including a set of instructions which, if executed by the programmable processor, cause the programmable processor to identify a plurality of areas in the image frame;
- and
- fixed functionality logic to determine phase information for the image frame on an area-by-area basis, wherein the instructions, if executed by the programmable processor, further cause the programmable processor to identify motion associated with the image frame based at least in part on the phase information, and wherein the fixed functionality logic is to:
- conduct an area specific inner product determination with respect to the image frame and a detector vector to determine phase information for a first area;
- and
- repeat the area specific inner product determination for the plurality of areas to determine the phase information for the image frame.
