HoughVision

Discover the power of computer vision with HoughVision - an fun app that demonstrates the Hough Transform algorithm for detecting geometric shapes in images.

Key Features:
🔹 Line Detection
Real-time line detection using polar coordinate parameter space
Adjustable vote threshold for sensitivity control
Visual parameter space heatmap showing voting accumulation
Multiple preset shapes: parallel lines, triangles, grids, and random patterns

🔹 Circle Detection
Circle detection with center and radius voting
Configurable radius range for targeted detection
Olympic rings, concentric circles, and random circle presets
Visual feedback showing detected circles overlaid on original image

🔹 Real-World Examples
Lane detection simulation for autonomous driving applications
Coin detection and counting demonstration
Understand practical applications of the Hough Transform

How It Works:
Draw or load preset shapes on the canvas
Adjust detection parameters (threshold, radius range)
Run the Hough Transform algorithm
View the parameter space heatmap
See detected shapes highlighted on your image

Technical Details:
Pure algorithm implementation (no external vision libraries)
Real-time parameter space visualization
Edge detection using Sobel operators
Local peak detection in accumulator array
No internet required for core features

Privacy First:
All processing happens on your device
