# PPHumanSeg
This model is ported from [PaddleHub](https://github.com/PaddlePaddle/PaddleHub) using [this script from OpenCV](https://github.com/opencv/opencv/blob/master/samples/dnn/dnn_model_runner/dnn_conversion/paddlepaddle/paddle_humanseg.py).
## Demo
### Python
Run the following command to try the demo:
```shell
# detect on camera input
python demo.py
# detect on an image
python demo.py --input /path/to/image -v
# get help regarding various parameters
python demo.py --help
```
### C++
Install latest OpenCV and CMake >= 3.24.0 to get started with:
```shell
# A typical and default installation path of OpenCV is /usr/local
cmake -B build -D OPENCV_INSTALLATION_PATH=/path/to/opencv/installation .
cmake --build build
# detect on camera input
./build/opencv_zoo_human_segmentation
# detect on an image
./build/opencv_zoo_human_segmentation -i=/path/to/image
# get help messages
./build/opencv_zoo_human_segmentation -h
```
### Example outputs
---
Results of accuracy evaluation with [tools/eval](../../tools/eval).
| Models | Accuracy | mIoU |
| ------------------ | -------------- | ------------- |
| PPHumanSeg | 0.9581 | 0.8996 |
| PPHumanSeg quant | 0.4365 | 0.2788 |
\*: 'quant' stands for 'quantized'.
