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.
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
yarn install #or, npm
# build dist/contours
npm run build
# run tests
npm test
# run tests on file change
npm run test:watchYou 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.
