Person Detection 256x480 (SR100 Series)

Model Overview

The Person Detection 256x480 model developed by Synaptics, is a lightweight quantized tflite model developed for the SR100 processor in the Synaptics Astra™ SR MCU Series.

The output includes the precise location of each person in the image along with a confidence value, enabling reliable person detection even on resource-constrained devices. The model is optimized to fit in Flash and is designed to fit in SRAM as well.

Model Features

• Model Type: Person Detection
• Input Size: 256x480
• Output: For each detected person, the model outputs bounding box coordinates and confidence scores.
• Classes: Single class (person); model is designed specifically for person detection.

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 detection on embedded, resource-constrained edge devices. Example applications include:

• Human presence and activity monitoring
• Fitness and wellness tracking
• Smart home automation
• Interactive user interfaces
• Security and access control

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.
