Person Classification 448×640 (SR100 Series)

Model Overview

The Person Classification 448×640 model, developed by Synaptics, is a lightweight quantized tflite model developed for the SR100 processor in the Synaptics Astra™ SR MCU Series.

It efficiently classifies input images as either person or non-person, enabling reliable human presence detection. This model can fit in Flash and designed to fit in SRAM as well.

Model Features

• Model Type: Binary classification
• Input Size: 448×640
• Classes:
  • 0: Non-person
  • 1: Person

Deployment on Astra

You can optimize this model for Synaptics Astra SR100 MCU using our our hosted SR100 Model Compiler HF Space.

• Processor: Astra™ SR100 MCU
• Platform: Astra™ Machina Micro Dev Kit
• Quantization: INT8 (fully quantized)
• Compiler: SR100 Model Compiler
• Preprocessing: Input images must be resized and quantized to match model requirements

Intended Applications

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

• Smart home and office presence detection
• Wake-on-person activation
• Security and surveillance systems

Evaluate Model

You can evaluate and test this model directly in our hosted Hugging Face Space, optimized for Synaptics SR110 MCU. This space provides a seamless sandbox for model evaluation using hardware-specific quantization and runtime settings.
