+# Attribute Recognition Modules of PP-Human
+
+Pedestrian attribute recognition has been widely used in the intelligent community, industrial, and transportation monitoring. Many attribute recognition modules have been gathered in PP-Human, including gender, age, hats, eyes, clothing and up to 26 attributes in total. Also, the pre-trained models are offered here and users can download and use them directly.

+1. The precision of detection/ tracking models is MOT17, obtained by conducting the integration training and testing of CrowdHuman, HIEVE, and some business data.
+2. The precision of pedestiran attribute analysis is PA100k, obtained by conducting the integration training and testing of RAPv2, PETA, and some business data.
+3. The inference speed is T4, the speed of using TensorRT FP16.
+
+## Instruction
+
+1. Download the model from the link in the above table, and unzip it to```./output_inference```.
+2. When inputting the image, run the command as follows:
+```python
+python deploy/pphuman/pipeline.py --config deploy/pphuman/config/infer_cfg.yml \
+                                                   --image_file=test_image.jpg \
+                                                   --device=gpu \
+                                                   --enable_attr=True
+```
+3. When inputting the video, run the command as follows:
+```python
+python deploy/pphuman/pipeline.py --config deploy/pphuman/config/infer_cfg.yml \
+                                                   --video_file=test_video.mp4 \
+                                                   --device=gpu \
+                                                   --enable_attr=True
+```
+4. If you want to change the model path, there are two methods：
+
+    - In ```./deploy/pphuman/config/infer_cfg.yml``` you can configurate different model paths. In attribute recognition models, you can modify the configuration in the field of ATTR.
+    - Add `--model_dir` in the command line to change the model path：
+```python
+python deploy/pphuman/pipeline.py --config deploy/pphuman/config/infer_cfg.yml \
+                                                   --video_file=test_video.mp4 \
+                                                   --device=gpu \
+                                                   --enable_attr=True \
+                                                   --model_dir det=ppyoloe/
+```

+## Introduction to the Solution 
+
+1. The PP-YOLOE model is used to handle detection boxs of input images/videos from object detection/ multi-object tracking. For details, please refer to the document [PP-YOLOE](../../../configs/ppyoloe).
+2. Capture every pedestrian in the input images with the help of coordiantes of detection boxes.
+3. Analyze the listed labels of pedestirans through attribute recognition. They are the same as those in the PA200k dataset. The label list is as follows:
+```
+- Gender
+- Age: Less than 18; 18-60; Over 60
+- Orientation: Front; Back; Side
+- Accessories: Glasses; Hat; None
+- HoldObjectsInFront: Yes; No
+- Bag: BackPack; ShoulderBag; HandBag
+- TopStyle: UpperStride; UpperLogo; UpperPlaid; UpperSplice 
+- BottomStyle: LowerStripe; LowerPattern
+- ShortSleeve: Yes; No
+- LongSleeve: Yes; No
+- LongCoat: Yes; No
+- Trousers: Yes; No
+- Shorts: Yes; No
+- Skirt&Dress: Yes; No
+- Boots: Yes; No
+```
+
+4. The model adopted in the attribute recognition is [StrongBaseline](https://arxiv.org/pdf/2107.03576.pdf), where the structure is the multi-class network structure based on ResNet50, and Weighted BCE loss and EMA are introduced for effect optimization.
