Abstract
An image processing system includes at least two, complementary, angle sensitive pixel (ASP) structures, having a spatial frequency domain ASP output including a background output and a plurality of ASP response outputs, in response to an optical input; an ASP response output subtractor component, which functions to suppress the background output and perform a subtraction of at least two of the ASP response outputs; and a processing component that can process the subtracted spatial frequency domain ASP response outputs. An optical domain image processing method includes the steps of providing at least two, complementary, angle sensitive pixel (ASP) structures; obtaining a spatial frequency domain ASP output including a plurality of complementary ASP response outputs, in response to an optical input; performing a wavelet-like transform of the ASP response outputs in the optical domain prior to performing any operation in a digital domain; and obtaining a desired output of the optical input.
