A method performed by a photon imaging system comprises: selecting first patterns for illumination, and generating first illumination patterns that are time-varying responsive to the first patterns in order to illuminate a target; detecting light energy of the first illumination patterns that is reflected by the target; constructing histograms of the light energy that is detected; reconstructing an image of the target using the histograms and the first patterns; performing feedback processing of the image based on an operational objective, associated with one or more of generating illumination patterns or reconstructing the image, to produce feedback for selecting second patterns that differ from the first patterns and are configured to achieve the operational objective; and responsive to the feedback, selecting the second patterns, and generating second illumination patterns based on the second patterns to illuminate the target.

Embodiments relate to compressive line sensing imaging. Initially, a codebook is configured with a pattern sequence for a series of illumination patterns. Each light element in an individually addressable laser diode array (IALDA) is independently controlled to project the series of illumination patterns onto a target. Next, measurements of the target are acquired based on the series of illumination patterns. The codebook is then used to decode the measurements to create an image of the target.

Systems and methods for object enumeration in a culture tank. The methods comprise: obtaining an array of two dimensional images of an illuminated scene in a culture tank; correcting non-uniform background illumination in the two dimensional images; improving a color contrast between a background and object edges shown in the two dimensional images; performing a defocus analysis using the two dimensional images to generate a focus map image; generating a modified focus map image by eliminating isolated spots shown in the focus map image and merging relatively small spots with adjacent relatively large objects in the focus map image; classifying each object shown in the modified focus map image as an object of interest or an object of no interest; and counting the number of objects classified as objects of interest.
