## Description

lite.ai.toolkit is a C++ computer vision toolkit designed for edge AI deployment. It enables the execution of pre-trained models for object detection, image classification, and segmentation on resource-constrained devices.

The project features a multi-backend inference engine that supports the ONNX model runtime, allowing AI models to run across different hardware targets. It includes a GPU-accelerated pipeline specifically for NVIDIA hardware to reduce latency and increase processing speed.

The toolkit covers a broad range of facial analysis capabilities, including emotion detection, gender and age estimation, and head pose analysis. It also provides tools for facial recognition through the extraction of feature embeddings and the computation of cosine similarity to verify identities. 

Additional capabilities include image matting for foreground isolation, grayscale image colorization, and artistic style transfer.
