Interactive Template Matching Explorer
Educational tool demonstrating template matching algorithms through visual "Where's Waldo" gameplay
🎮 Try it now: Launch Interactive Demo
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
