METHOD FOR REDUCING ROW AND COLUMN NOISE IN IMAGING SYSTEMS

摘要

A method for the reduction of noise in an image including identifying neighboring pixel values in pixels proximate to a subject pixel; comparing the neighboring pixel values to a preset tolerance range; using neighboring pixel values within the tolerance range to calculate a pixel intensity correction value; and applying the pixel intensity value to the subject pixel.

1. A method for the redaction of noise in an image, said method comprising:
identifying a homogeneous set of pixels near a subject pixel in a pixel group wherein each homogenous pixel in said homogenous set of pixels has a difference in pixel intensity value of said homogenous pixel and pixel intensity of each other homogenous pixel in said homogenous set of pixels is within a preset tolerance; calculating a pixel intensity correction value by taking the difference between an average pixel intensity of said homogenous set of pixels and pixel intensity of said subject pixel; averaging said pixel intensity correction over said pixel group; applying said pixel intensity correction to said subject pixel.
