Non-Uniformity Correction for Infrared Images

This MATLAB source code implements non-uniformity correction for infrared images. The code has been thoroughly tested and demonstrated error-free performance, effectively correcting non-uniformity in infrared imagery.

The implementation begins with preprocessing stages including grayscale conversion and noise filtering using built-in MATLAB functions like rgb2gray() and medfilt2(). Subsequently, the code employs image-based statistical methods to estimate non-uniformity correction parameters. Key algorithms involve calculating local statistics through block processing and adaptive thresholding to determine correction factors for different image regions.

The correction parameters are then applied pixel-wise across the image using matrix operations to eliminate non-uniformity effects. The code includes utility functions for parameter optimization and comprehensive inline documentation explaining each processing step.
