Information

!Mona

Dependencies

You need to install opencv for this to work right.

Usage

$3

``coffee-script
faces = require 'faces'
fs = require 'fs'

mona = fs.readFileSync 'mona.png'

faces.find mona, (err, faces) ->
console.log "There are #{faces.length} faces"
`

$3

`coffee-script
faces = require 'faces'

faceStream = faces.createStream
scale: 2
min: [10, 10]
draw: # optional, only specify this if you want to alter the image
type: 'ellipse'

videoStream = someStream()
videoStream.pipe faceStream

faceStream.on 'data', (frame, faces) ->
# frame is an image buffer
# faces is an array of faces
`

Docs

$3

createStream returns a readable/writeable stream that you can pipe image buffers too. Takes most image formats (png, jpeg, tiff, etc.) - .write(image buffer) and it will .emit('data', image buffer, faces, cvimg)

$3

The actual facial recognition worker. opt is optional. Callback receives (err, faces) where faces is an array of `{x,y,height,width}`

$3

opt.type can be either ellipse or rectangle
opt.color = [0,255,0] by default
opt.thickness is 0-255
cb receives (err, buff) where buff is a new image buffer

$3

Turns an image buffer into a base64 data uri - useful for rendering to a webpage or sending over websockets.

$3

Load a custom OpenCV cascade file. (example: `faces.load("cars.xml")``)
