ST offers a complete portfolio of products and solutions for the IoT; making everything smarter, from homes, cities, and industry to all the “Smart Things” that populate our world and make positive contributions to our lives. Highlighted solutions include AR/VR/MR, voice control, imaging, AI, and wireless charging.

Contextual Activity Recognition

Distributed intelligence between ST Smart Sensor Machine Learning Core and a neural network running on STM32 microcontroller.

• Ultra-low-power always-on Human Activity Recognition on LSM6DSOX Machine Learning Core
• Low-power sound analysis neural network running on STM32L4 triggered by the activity recognition
• Audio and motion are combined to recognize 5 activities (stationary, walking, running, biking, driving) in 3 different contexts (outdoor, indoor or in vehicle)

ST Parts: SensorTile.box

Face Expression Recognition

Live face expression recognition from a camera video stream.

• Detection of multiple faces with labeled bounding box displayed in real-time
• Recognizes 7 expressions: angry, disgusted, scared, happy, neutral, sad, surprised
• Preprocessing, face detection, image cropping and scaling are performed by the STM32H747

ST Parts: STM32H747 Discovery Kit

Face Identification

Detection and identification of multiple faces with bounding box displayed in real-time from a live video feed.

• Enrollment via PC of up to 8 new faces
• Preprocessing, face detection, image cropping and scaling are performed by the STM32H747

Image Classification on Microprocessor

Advanced classification of images among 1000 different categories using Tensor Flow Lite on the STM32MP1 dual-core MPU.

• Images are classified with MobileNet v1: 1000 classes at 8 frames per second
• Tensor Flow Lite integrated via C++ runtime implementation on dual-core A7
• Avenger96 board with parallel interface Camera daughter board. Allows optimal image
  capture without USB overhead

Condition Monitoring of a Multi-Fan System

NanoEdge AI Studio by Cartesiam easily creates custom machine learning library able to learn and infer in STM32 microcontrollers. No data set, no data scientist, no pre-trained Artificial Neural Network required.

• Vibration analysis in a multi-source and noisy environment
• On-chip learning of the normal condition
• On-chip anomaly detection such as shock, clogging, etc. is displayed real-time
