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.
