Basic

Basic example that reads frames from a connected webcam, and processes them using a wasmCV guest module compiled using TinyGo.

The host application is a Go application written using GoCV Go language wrappers for OpenCV and the Wazero WASM runtime.

Compile the guest module

$ cd modules/processor
$ tinygo build -o ../processor.wasm -target=wasm-unknown .
$ cd ../..

Run the host application

$ go run .
Defining host function...
Start reading device: /dev/video0

It will then capture each frame, display some stats, and them perform a gaussian blur on the source image.
