Find a template image inside a source image. Upload source and template, choose a matching method, and get the match location highlighted.
All processing runs locally in your browser. Your files never leave your device.
What Template Matching Is Useful For
Template matching is useful for interface QA, repetitive part inspection, screen automation prototypes, logo localization, and visual search tasks where you already know what the target patch should look like. The workflow highlights likely matches inside the larger source image.
How to Run Template Matching in 3 Steps
- Upload. Upload your input image via the upload zone. Most dev tools accept JPG, PNG, and WebP input for fastest processing.
- Process. Tune the algorithm parameters using the control panel — watch the live preview update as you adjust thresholds, kernel sizes, and other settings.
- Download. Export the processed image or result visualization. Use it directly or continue to another dev tool in your pipeline.
Why Use Template Matching in the Browser
- Instant Feedback — See parameter changes reflected in real time. No recompile, no Python environment setup, no Jupyter kernel.
- Teaching-Friendly — Perfect for demonstrating classical computer vision concepts in class without installing OpenCV locally.
- Prototype Faster — Test algorithm behavior on real images before writing production code.
- Zero Install — Built on OpenCV primitives compiled to WebAssembly — full featured, fully local.
Template Matching FAQ
What computer vision library does Template Matching use?
Template Matching is built on OpenCV primitives compiled to WebAssembly. You get the same algorithms as the desktop OpenCV library, running with near-native performance in your browser.
Can I download the processed result?
Yes. Every dev tool supports exporting the processed image or visualization as PNG. You can use it in documentation, papers, or downstream tools.
Are there parameter presets?
Template Matching ships with sensible defaults that work for most images. Adjust the controls to experiment with different parameters — changes reflect in the live preview immediately.
