Detailed Documentation

This document discusses methodologies for computing Image Modulation Transfer Function (MTF) to enhance image clarity. The implementation involves analyzing edge spread functions (ESF) through line spread function (LSF) derivation, followed by Fourier transformation to obtain frequency response characteristics. This technique applies to diverse image types including standard photographs and satellite imagery, enabling quantitative assessment of edge sharpness and detail preservation capabilities. As imaging technology evolves, MTF computation algorithms continuously adapt through optimized windowing functions and noise reduction techniques. Key implementation steps include: edge detection using Sobel/Canny operators, ESF fitting with polynomial regression, and frequency domain conversion using FFT algorithms. Understanding and applying MTF principles remains crucial for optimizing image quality and improving visual perception in computer vision systems.
