const baboon = require('baboon-image');
const save = require('save-pixels');
const fs = require('fs');
const streamToPromise = require('stream-to-promise');
const mean = require('ndarray-mean');
const fs = require('fs');

const images = [lena, baboon];
const average = mean(images);

streamToPromise(save(average, 'png')).then(imageBuffer => {
  fs.writeFileSync('average.png', imageBuffer);
});
