This is a person reidentification model for a general scenario. It uses a whole body image as an input and outputs an embedding vector to match a pair of images by the cosine distance. The model is based on the OmniScaleNet backbone developed for fast inference. A single reidentification head from the 1/16 scale feature map outputs an embedding vector of 256 floats.
|Market-1501 rank@1 accuracy||86.1 %|
|Market-1501 mAP||59.7 %|
|Pose coverage||Standing upright, parallel to image plane|
|Support of occluded pedestrians||YES|
The cumulative matching curve (CMC) at rank-1 is accuracy denoting the possibility to locate at least one true positive in the top-1 rank. Mean Average Precision (mAP) is the mean across Average Precision (AP) of all queries. AP is defined as the area under the precision and recall curve.
The net expects one input image of the shape
1, 3, 256, 128 in the
B, C, H, W format, where:
B- batch size
C- number of channels
H- image height
W- image width
The expected color order is
The net outputs a blob with the
1, 256 shape named
descriptor which can be compared with other descriptors using the cosine distance.
