NPM link: object-detection

Installation

npm install object-detection

Usage


var detectObject = require('object-detection')

// Tweak the Sensitivity and the Tolerance for optimal result

var config = {
  imageName: 'path-to-image', // preferrably in JPG format and less than 100 kB
  sensitivity: 50, // ranges from 1 to 100
  tolerance: 50, // ranges from 1 to 100
}

detectObject(config).then(function(response) {

  var base64Img = response.base64Img

  // use base64Img in html image tag ...
  imageElement.setAttribute('src', 'data:image/jpeg;base64,' + base64Img)

  // save base64Img as image file ...
  fs.writeFile('object.jpg', base64Img, { encoding: 'base64' }, function() {
  	console.log('Saved object image')
  })
  
})

Caution

  • Use small images, preferably in JPG format and less than 100 kB
  • Currently works for single object.
  • Behaviour is not strongly defined for multi-objects.
  • Contiguous objects are considered as single object.
  • Optimizer is not well tuned yet.
