1. A feature detection system, comprising:
a lens assembly to focus light of an optical image onto a microlens array that replicates the optical image to form a plurality of optical image replicas;
a plurality of optical filters, wherein each optical filter is placed within an optical path of one of the optical image replicas, each optical filter configured to selectively filter one of the optical image replicas, wherein the plurality of optical filters comprises a plurality of binary optical filter masks; and
a multipixel image sensor comprising:
a segmented detection region of pixels to receive each of the filtered optical image replicas from the plurality of optical filters for feature detection, and
an image capture region of pixels to capture a high-resolution image of the optical image.
