Recent updates

  • 2022.6.15 Release Practical Ultra Light-weight image Classification solutions. PULC models inference within 3ms on CPU devices, with accuracy on par with SwinTransformer. We also release 9 practical classification models covering pedestrian, vehicle and OCR scenario.

  • 2022.4.21 Added the related code of the CVPR2022 oral paper MixFormer.

  • 2021.09.17 Add PP-LCNet series model developed by PaddleClas, these models show strong competitiveness on Intel CPUs. For the introduction of PP-LCNet, please refer to paper or PP-LCNet model introduction. The metrics and pretrained model are available here.

  • 2021.06.29 Add Swin-transformer) series model,Highest top1 acc on ImageNet1k dataset reaches 87.2%, training, evaluation and inference are all supported. Pretrained models can be downloaded here.

  • 2021.06.16 PaddleClas release/2.2. Add metric learning and vector search modules. Add product recognition, animation character recognition, vehicle recognition and logo recognition. Added 30 pretrained models of LeViT, Twins, TNT, DLA, HarDNet, and RedNet, and the accuracy is roughly the same as that of the paper.

Introduction to Practical Ultra Light-weight image Classification solutions

PULC solutions consists of PP-LCNet light-weight backbone, SSLD pretrained models, Ensemble of Data Augmentation strategy and SKL-UGI knowledge distillation. PULC models inference within 3ms on CPU devices, with accuracy comparable with SwinTransformer. We also release 9 practical models covering pedestrian, vehicle and OCR.

Introduction to Image Recognition Systems

Image recognition can be divided into three steps:

  • (1)Identify region proposal for target objects through a detection model;
  • (2)Extract features for each region proposal;
  • (3)Search features in the retrieval database and output results;

For a new unknown category, there is no need to retrain the model, just prepare images of new category, extract features and update retrieval database and the category can be recognised.
