# Person Pose Detection 480x640 (SR100 Series)

## Model Overview

The **Person Pose Detection 480x640** model developed by Synaptics, is a lightweight quantized `tflite` model developed for the **SR100 processor** in the Synaptics Astra™  SR MCU Series. 

It efficiently generates bounding boxes and identifies 17 keypoints for each person, corresponding to various body parts. Each keypoint is accompanied by a confidence score that indicates the reliability of the detection, enabling accurate estimation of the person's pose. This model can fit in Flash and designed to fit in SRAM as well.

## Model Features

- **Model Type:** Pose Detection
- **Input Size:** 480x640 
- **Output:** For each detected person, the model outputs bounding box coordinates, 17 keypoint locations and confidence scores.
- **Classes:** Single class (person); model is designed specifically for pose estimation of people.



## Deployment on Astra

You can optimize this model for Synaptics Astra SR100 MCU using our our hosted [SR100 Model Compiler HF Space](https://huggingface.co/spaces/Synaptics/SR100-Model-Compiler).

- **Processor:**  Astra™ SR100 MCU
- **Platform:**  Astra™ Machina Micro Dev Kit
- **Quantization:** INT8 (fully quantized)
- **Compiler:** [SR100 Model Compiler](https://huggingface.co/spaces/Synaptics/SR100-Model-Compiler)
- **Preprocessing:** Input images must be resized and quantized to match model requirements

## Intended Applications

Designed for **real-time person pose estimation** on embedded, resource-constrained edge devices. Typical use cases include:

- Human activity recognition and gesture control
- Fitness and wellness tracking
- Smart home automation based on body posture
- Interactive applications and user interfaces


## Evaluate Model

You can evaluate and test this model directly in our hosted [Hugging Face Space](https://huggingface.co/spaces/Synaptics/SR100-Model-Compiler),  optimized for **Synaptics SR110** MCU. This space provides a seamless sandbox for model evaluation using hardware-specific quantization and runtime settings.
