Interactive Template Matching Explorer

Educational tool demonstrating template matching algorithms through visual "Where's Waldo" gameplay

Live Demo GitHub Repository

What It Does

Find Waldo by manually sliding his template across cluttered scenes. Watch correlation values update in real-time to understand how template matching algorithms detect objects.

Key Features: Interactive sliding, real-time correlation heatmaps, progressive difficulty levels

Why It Matters

Template matching is fundamental to computer vision. This hands-on demo makes abstract correlation concepts tangible—drag the template and immediately see how mathematical similarity translates to visual object detection.

What You’ll Learn

  • Sliding window search strategies
  • Correlation as a similarity measure
  • Algorithm limitations (rotation, scale, lighting)
  • Foundation for understanding CNNs and modern detection methods
