ReID Models
Use this page to compare ReID backbones by compute, parameter count, embedding size, and available same-domain evaluation results.
Model Reference
Same-domain scores are reported as rank-1 (mAP). Rows with - do not yet have a documented same-domain result in this table. GFLOPs are input-size dependent and should be read together with the Input column; rows are not normalized to one common crop.

The linked OSNet scores use the published same-domain softmax setup with 256x128 input, random flip augmentation, and Euclidean distance. The lmbn_n scores are the LightMBN paper row reported as Ours LightMBN with an OSNet backbone. MobileNetV4, LMBN, and CSL-TinyViT rows use the 384x128 BoxMOT ReID crop used by their training configs.
