## Description

BackgroundMattingV2 is a deep learning background matting tool and real-time image segmentation framework. It provides a system for isolating foreground subjects from high-resolution images and video feeds in real time.

The project includes a deep learning model trainer for optimizing matting models through base convergence and end-to-end refinement. It also functions as a cross-runtime model exporter, converting trained neural networks into interchangeable formats for deployment across different software environments and hardware runtimes.

The framework supports streaming processed webcam feeds to a virtual camera and utilizes trimap-guided foreground estimation to separate subjects from their backgrounds. Additional capabilities cover pixel-level alpha matting and the training of models using custom datasets.
