autoseg | Automatic Fast WebAssembly Image Segmentation\n\n\u003e Are you looking to convert UDT annotations into png masks? Use [udt-to-png](https://github.com/UniversalDataTool/udt-to-png)\n\nautoseg segments images from a list of points and polygons containing\nclassifications. Autoseg was originally created by [Severin Ibarluzea](https://twitter.com/seveibar) for usage with the [Universal Data Tool](https://github.com/UniversalDataTool/universal-data-tool).\n\n## Features\n\n- Simple API\n- WebWorker background computation\n- Deterministic, suitable for mask compression\n- Fast. WebAssembly compiled from state of the art C++ implementations of SLIC superpixeling and graph cut\n- Fully compliant with the [Universal Data Tool](https://github.com/UniversalDataTool/universal-data-tool) and [UDT Format](https://github.com/UniversalDataTool/udt-format)\n\n## Example Inputs -\u003e Output\n\n### Input Image\n\n![Input Image](https://user-images.githubusercontent.com/1910070/88559148-75011400-cffa-11ea-912e-e4d53a64dc8d.png)\n\n### Input Polygon\n\n![Input Image Polygon](https://user-images.githubusercontent.com/1910070/88559149-7599aa80-cffa-11ea-9d7b-34f4190750f8.png)\n\n### Output Mask\n\n![Output Mask](https://user-images.githubusercontent.com/1910070/88559147-75011400-cffa-11ea-9ac7-d99e7bc77646.png)\n\n## CLI\n\nMake sure to format your file in the [\\*.udt.json format](https://github.com/UniversalDataTool/udt-format).\n\n```bash\nnpm install -g autoseg\n\n# This will output a bunch of image pngs for the masks of a udt file\nautoseg some_file.udt.json -o output-directory\n\n\nautoseg --help\n\n# Usage: autoseg path/to/dataset.udt.json -o output-masks-dir\n#\n# Options:\n#   --help               Show help                                       [boolean]\n#   --version            Show version number                             [boolean]\n#   --use-sample-number  Use the number of the sample as the mask filename\n#                       (mask0001.png, etc.)\n#   --output-dir, -o     Output directory for masks                     [required]\n```\n\n## API\n\n```javascript\nconst autoseg = require(\"autoseg\") // OR require(\"autoseg/node\")\n\nawait autoseg.loadImage({ data: imData, width: 320, height: 249 })\n\n// Points/polygons are in the UDT Shape format\n// https://github.com/UniversalDataTool/udt-format\nconst maskImageData = await autoseg.getMask([\n  { regionType: \"point\", x: 50, y: 50, cls: 0 },\n  { regionType: \"point\", x: 150, y: 150, cls: 1 },\n])\n\n// If you have a canvas, you can draw the image of the mask\ncanvasContext.putImageData(maskImageData, 0, 0)\n\n// NOTE: nodejs doesn't have builtin support for ImageData, but you\n// can use the returned data in a similar way, it's an object with\n// { data: Uint8ClampedArray, width: number, height: number }\n```\n\n## Configuring\n\n```javascript\nawait autoseg.setConfig({\n  maxClusters: 1000,\n  classNames: [\"dog\", \"cat\"],\n  classColors: [0xffffffff, 0xff000000],\n})\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Funiversaldatatool%2Fautoseg","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Funiversaldatatool%2Fautoseg","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Funiversaldatatool%2Fautoseg/lists"}
