contours)

This is a basic script for pulling out contours/regions from an image.

It uses Moore Neighbourhood contour tracing. For more details on the algorithm/approach see this site.

``js const output = contours(imageData)

// list of matching contours`

* imageData should be thresholded (any non-zero pixel is counted as _on_) * only the red value is the only one used

`Development`

`bash yarn install #or, npm

`build dist/contours`


npm run build
run tests

npm test

# run tests on file change npm run test:watch``

Status

You probably shouldn't use this or whatever.

This is at the state of "just about working". There's a few things that would make it a load more efficient, and maybe a bit nicer to use. Feedback would be appreciated.
