    Adaptive Threshold in JavaScript. Both in Node.js and browser.

    Install

    $ npm install adaptive-threshold
    

    Usage

    I made it as an ndarray module. So, the simplest usage is with get-pixels and save-pixels as below.

    const fs = require('fs')
    const savePixels = require('save-pixels')
    const getPixels = require('get-pixels')
    const adaptiveThreshold = require('adaptive-threshold')
     
    getPixels('src.png', (err, pixels) => {
      if (err) {
        console.error(err)
        return
      }
      let thresholded = adaptiveThreshold(pixels)
      savePixels(thresholded, 'png').pipe(fs.createWriteStream('dist.png'))
    })

    API

    adaptiveThreshold(pixels[, options])

    Returns a thresholded ndarray.

    • pixels - an ndarray whose shape is [width, height, channels].
    • options.size - the size of neighbourhood area.
    • options.compensation - a constant which is subtracted from the mean.

    Install

    npm i adaptive-threshold
