    摘要: An image processing system includes a wavefront coding element that codes a wavefront forming an optical image, a detector for converting the optical image to a data stream and an image processor for processing the data stream with a reduced set filter kernel to reverse effects of wavefront coding and generate a final image. The reduced set filter kernel may include a reduced set distributive filter kernel. An image processing method includes wavefront coding a wavefront that forms an optical image, converting the optical image to a data stream, and processing the data stream with a reduced set filter kernel to reverse effects of wavefront coding and generate a final image. The processing consists of processing the image, for each pixel, with filter tap logic consisting of a shifter.

    摘要: Systems and methods include optics having one or more phase modifying elements that modify wavefront phase to introduce image attributes into an optical image. A detector converts the optical image to electronic data while maintaining the image attributes. A signal processor subdivides the electronic data into one or more data sets, classifies the data sets, and independently processes the data sets to form processed electronic data. The processing may optionally be nonlinear. Other imaging systems and methods include optics having one or more phase modifying elements that modify wavefront phase to form an optical image. A detector generates electronic data having one or more image attributes that are dependent on characteristics of the phase modifying elements and/or the detector. A signal processor subdivides the electronic data into one or more data sets, classifies the data sets and independently processes the data sets to form processed electronic data.
