Face Match

The face detection api compares faces in two different pictures and tells the similarity between them. A typical use of this is matching identity documents with pictures of a person.

Example

Here we shall compare two pictures of obama

test-image6.jpeg
test-image7.jpg 
const request = require("request")
const fs = require("fs")

image_stream1 = fs.createReadStream("test-image6.jpeg")
image_stream2 = fs.createReadStream("test-image7.jpg")

var form = {"image1":image_stream1,"image2":image_stream2}

request.post({url:"http://localhost:80/v1/vision/face/match", formData:form},function(err,res,body){

    response = JSON.parse(body)
    console.log(response)
})

Result

{ success: true, similarity: 0.73975885 }

Here we shall compare a picture of Obama with that of Bradley Cooper

test-image6.jpeg
test-image8.jpg 
const request = require("request")
const fs = require("fs")

image_stream1 = fs.createReadStream("test-image6.jpeg")
image_stream2 = fs.createReadStream("test-image8.jpg")

var form = {"image1":image_stream1,"image2":image_stream2}

request.post({url:"http://localhost:80/v1/vision/face/match", formData:form},function(err,res,body){

    response = JSON.parse(body)
    console.log(response)
})

Result

{ success: true, similarity: 0.4456826 }

As seen above, the match for two different pictures of Obama was very high while the match for Obama and Bradley Cooper was very low.

Performance

DeepStack offers three modes allowing you to tradeoff speed for peformance. During startup, you can specify performance mode to be , "High" , "Medium" and "Low"

The default mode is "Medium"

You can speciy a different mode as seen below

sudo docker run -e MODE=High -e VISION-FACE=True -v localstorage:/datastore \
-p 80:5000 deepquestai/deepstack

Note the -e MODE=High above
