aws rekognition 打印边界框

Question

我正在尝试从边界框打印出内容，问题是，如果图像有两个或更多面孔，作业将 return 两个或更多边界框，那么我该如何打印出来？

我尝试编写一个循环来读取 str 'BoundingBox' 并打印，但它只 return 两次第一个边界框。谁能给我一些想法？谢谢

i=0
for bBox in response:
    print('found face at...')
    bBox = response['FaceDetails'][i]['BoundingBox']
    print("BoundingBox: ({}%)".format(bBox['Width']))
    print("BoundingBox: ({}%)".format(bBox['Height']))
    print("BoundingBox: ({}%)".format(bBox['Left']))
    print("BoundingBox: ({}%)".format(bBox['Top']))
    i+=i

格式为：

这是它的内容 returns:

found face at...
BoundingBox: (0.49861112236976624%)
BoundingBox: (0.2796874940395355%)
BoundingBox: (0.43611112236976624%)
BoundingBox: (0.27656251192092896%)
found face at...
BoundingBox: (0.49861112236976624%)
BoundingBox: (0.2796874940395355%)
BoundingBox: (0.43611112236976624%)
BoundingBox: (0.27656251192092896%)

Answer 1

for face in response['FaceDetails']:
    print ('Face found at...')
    box = face['BoundingBox']
    for key,value in box.items():
        print key, value

Returns:

Width 0.49861112237
Top 0.276562511921
Left 0.43611112237
Height 0.27968749404
Face found at...
Width 0.379166662693
Top 0.297656238079
Left 0.126388892531
