BiSeNet: Bilateral Segmentation Network for Real-time Semantic Segmentation

This is a face parsing model for high-precision facial feature segmentation based on BiSeNet: Bilateral Segmentation Network for Real-time Semantic Segmentation. This model accurately segments various facial components such as the eyes, nose, mouth, and the contour of the face from images. This repo provides a different training & inference code and new backbone model has been added.

Project Description

Face parsing model segments facial features with remarkable accuracy, making it ideal for applications in digital makeup, augmented reality, facial recognition, and emotion detection. The model processes input images and outputs a detailed mask that highlights individual facial components, distinguishing between skin, hair, eyes, and other key facial landmarks.

Following updates have been made so far:

• Prepared more clear training code
• Updated backbone models, added resnet34 model (initially it has only resnet18)
• Trained model weights/checkpoints with different backbones on Github Release
• Made several auxiliary updates to the code.
• torch to onnx convert
• onnx inference
