Continuing the previous #ArtificialIntelligence theme. Wanted to see what and how does Amazon’s rekognition work and different from the #AI offerings from the others, such as Microsoft.
Here is a #ProjectMurphy image’s confidence score. I am glad to see that there is a 99% confidence that this is a person.
The request POST is quite simple:
{ "method": "POST", "path": "/", "region": "us-west-2", "headers": { "Content-Type": "application/x-amz-json-1.1", "X-Amz-Date": "Thu, 01 Dec 2016 22:21:01 GMT", "X-Amz-Target": "com.amazonaws.rekognitionservice.RekognitionService.DetectLabels" }, "contentString": { "Attributes": [ "ALL" ], "Image": { "Bytes": "..." } } }
And so is the response:
{ "Labels": [ { "Confidence": 99.2780990600586, "Name": "People" }, { "Confidence": 99.2780990600586, "Name": "Person" }, { "Confidence": 99.27307891845703, "Name": "Human" }, { "Confidence": 73.7669448852539, "Name": "Flyer" }, { "Confidence": 73.7669448852539, "Name": "Poster" }, { "Confidence": 68.23612213134765, "Name": "Art" }, { "Confidence": 58.291263580322266, "Name": "Brochure" }, { "Confidence": 55.91957092285156, "Name": "Modern Art" }, { "Confidence": 53.9996223449707, "Name": "Blossom" }, { "Confidence": 53.9996223449707, "Name": "Flora" }, { "Confidence": 53.9996223449707, "Name": "Flower" }, { "Confidence": 53.9996223449707, "Name": "Petal" }, { "Confidence": 53.9996223449707, "Name": "Plant" }, { "Confidence": 50.69965744018555, "Name": "Face" }, { "Confidence": 50.69965744018555, "Name": "Selfie" } ] }
Here is what the facial analysis shows;
However how does it handle something a little more complex perhaps?
And finally, what of the comparison? I think there might be some more work to be done on that front.
Here is the response:
{ "FaceMatches": [ { "Face": { "BoundingBox": { "Height": 0.3878205120563507, "Left": 0.2371794879436493, "Top": 0.22435897588729858, "Width": 0.3878205120563507 }, "Confidence": 99.79533386230469 }, "Similarity": 0 } ], "SourceImageFace": { "BoundingBox": { "Height": 0.209781214594841, "Left": 0.4188888967037201, "Top": 0.13127413392066955, "Width": 0.18111111223697662 }, "Confidence": 99.99442291259765 } }
