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
}
],
