Abstract:
1. A compressive sensing-based bio-inspired shape feature detection imager circuit comprising a plurality of circuits operatively coupled to one another, the plurality of circuits comprising: an active pixel sensor array configured to collect an image in an original space and generate an analog representation of the collected image; a bio-inspired shape feature compressive sensing projection matrix circuit configured to project the analog representation of the collected image simultaneously onto each target bio-inspired feature of a set of target bio-inspired features and map the projected image from an original space to a compressive sensing space, and generate i) correlation data of the projected image in the compressive sensing space to the set of target bio-inspired features, and ii) reference position data in the original space for the collected image; a target detection and location circuit configured to process the correlation data and the reference position data to identify a potential target in the collected image from amongst the set of target bio-inspired features; a compressive sensing sampling data array circuit configured to process the projected image in the compressive sensing space to recover a digital representation of the collected image in the original space, and generate position and identity information of an identified potential target within the recovered collected image in the original space; and an adaptive target extraction circuit configured to track the identified potential target in a next collected image and extract a corresponding new feature from the next collected image to add to the set of target bio-inspired features.
