Abstract
Various examples of methods and systems are provided for compressive imaging using approximate message passing with denoising. According to an aspect, a method includes applying an approximate message passing (AMP) conversion framework to a plurality of substantially linear measurements for conversion into a plurality of scalar measurements. A denoiser algorithm can be applied to the plurality of scalar measurements to generate a plurality of denoised scalar measurements. Further, a conversion term can be applied to the plurality of denoised scalar measurements for converting the plurality of denoised scalar measurements to a plurality of denoised substantially linear measurements. The plurality of substantially linear measurements can represent two-dimensional or three-dimensional signals.
