Allow contiguous pixels only in superpixel tool #26

Open rytido opened 7 years ago

rytido commented 7 years ago

Is there a way to prevent the superpixel tool from associating non-contiguous pixels (aside from reducing the size)? For example, the red shapes below should be kept separate instead of associated as they currently are.

@doodnayr Currently there is no algorithm is implemented to force separating connected components, though some piece of code is relevant.

Temporarily you can try a different segmentation algorithm (e.g., slico) or set different minRegionSize to mitigate the issue.

Ok, I'm using slico, thank you. For anyone that might stumble on this, it can be set in js/app/edit.js:

superpixelOptions: { method: "slico", regionSize: 25 }

Also, making shapes finer or coarser (boundary -+ buttons) does not work unless you use "FixedK" method.
