Introducing GoCVKit: Zero-Boilerplate Computer Vision in Go

Source: Dev.to

Hey there, fellow Gophers! If you’ve worked with computer vision in Go, you know GoCV is fantastic for accessing OpenCV’s power.

But the reality? Boilerplate everywhere: camera setup, Mat management, window handling, resource leaks, and recompiling just to tweak a parameter. It’s not exactly “fun.”
That’s why I created GoCVKit—a modular framework that makes real‑time CV prototyping smooth, efficient, and genuinely enjoyable.

What is GoCVKit?

GoCVKit is a clean, idiomatic layer on top of GoCV for live camera or video streams. It handles the heavy lifting so you can focus on ideas, not plumbing.

Key features

• Zero boilerplate – Full apps in ≤10 lines.
• Hot‑reload config – Edit config.toml and changes apply instantly—no restarts.
• Performance‑focused – Double‑buffered pipelines with zero per‑frame allocations.
• Extensible – Built‑in processors (Grayscale, GaussianBlur, Canny, Sobel, etc.) plus easy custom filters.
• Quality‑of‑life extras – Video recording, toggleable FPS overlay, frame callbacks, graceful shutdown, and seamless input switching (webcam or file).

Why I Built This

Go is perfect for CV: fast, concurrent, and easy to deploy. But raw GoCV meant rewriting the same scaffolding repeatedly. GoCVKit eliminates that pain, making it ideal for:

• Rapid prototyping
• Teaching and demos
• Live presentations
• Real‑time vision apps
• Anyone who wants to stay sane while experimenting

Star it if it saves you time, contribute if you make it better, and tell your friends—Go deserves a first‑class CV experience! 🚀
