Abstract
An imaging system includes a Read-Out Integrated Circuit (ROIC) configured to receive high spatial resolution imagery having a detected amount of energy from a detection device. The ROIC includes a mask generator and a high-resolution image decode. The mask generator applies a pixel mask to the high spatial resolution imagery so as to generate compressed high spatial resolution imagery that preserves the detected amount of energy. The high-resolution image decoder receives the compressed high spatial resolution imagery and decompresses the compressed high spatial resolution imagery and obtain the high spatial resolution imagery having a detected amount of energy.

An imaging system comprising:
- a Read-Out Integrated Circuit (ROIC) configured to receive high spatial resolution imagery having a detected amount of energy from a detection device, the ROIC including a mask generator configured to apply a pixel mask to the high spatial resolution imagery so as to generate compressed high spatial resolution imagery that preserves the detected amount of energy;
- and
- a high-resolution image decoder in signal communication with the ROIC to receive the compressed high spatial resolution imagery, the high-resolution image decoder configured to decompress the compressed high spatial resolution imagery and obtain the high spatial resolution imagery having a detected amount of energy,
- wherein the mask generator generates the pixel mask according to a Hadamard matrix that defines a plurality of positive value measurement codes and negative value codes arranged in a plurality of rows and columns, each row indicating a frame and each column indicating a pixel with respect to the frame,
- wherein each pixel included in at least one of the rows has a positive measurement value code while excluding any negative measurement value codes.
A method of processing imagery data comprises:
- receiving, via a Read-Out Integrated Circuit (ROIC), a high spatial resolution imagery having a detected amount of energy from a detection device;
- generating, via a mask generator, a pixel mask according to a Hadamard matrix, and applying, via the ROIC, the pixel mask to the high spatial resolution imagery so as to generate compressed high spatial resolution imagery that preserves the detected amount of energy;
- and
- receiving, via a high-resolution image decoder;
- the compressed high spatial resolution imagery;
- decompressing, via the high-resolution image decoder, the compressed high spatial resolution imagery to obtain the high spatial resolution imagery having a detected amount of energy,
- wherein the Hadamard matrix is defined as a plurality of positive value measurement codes and negative value codes arranged in a plurality of rows and columns such that each row is indicative of a frame and each column is indicative of a pixel corresponding to the frame, each pixel included in at least one of the rows having a positive measurement value code while excluding any negative measurement value codes.
