This project implements line detection using Hough Transform to identify rectangular patterns in images and locate their centers. The method leverages image processing techniques and geometric properties of rectangles, validated through practical testing. The algorithm can distinguish rectangles among various shapes (including triangles, circles, hearts, etc.), demonstrating practical applicability. The complete MATLAB package includes working code, sample images, and detection examples with detailed implementation insights.

A line detection algorithm utilizing Hough transform that leverages point-line duality between image space and Hough parameter space. The implementation transforms detection problems from image space to parameter space, where simple accumulation statistics are performed. By identifying accumulator peaks in Hough parameter space, the program effectively detects lines. The core algorithm involves mapping edge points to sinusoidal curves in parameter space and detecting intersections through voting mechanisms.
