Description
X-LINUX-AI is an STM32 MPU OpenSTLinux Expansion Package that targets artificial intelligence for STM32MP1 and STM32MP2 series microprocessors. It contains Linux® AI frameworks, as well as application examples to get started with some basic use cases.
The examples provided in X-LINUX-AI include a selection of optimized models for image classification, object detection, semantic segmentation, human pose estimation, and face recognition.
These examples rely on the STAI_MPU API based on either the TensorFlow™ Lite inference engine, ONNX Runtime, or OpenVX™. They all support Python™ scripting and C/C++ applications.
