BEN2简介与核心功能

BEN2(Background Erase Network 2)是由Prama LLC开发的专用于自动移除图像背景的深度学习模型。其核心创新点在于采用Confidence Guided Matting(CGM)管道,通过基础模型与精细化网络的协同工作(处理低信心像素),实现亚像素级的前景分割精度。

  • 核心功能清单::
    • 自动生成二值掩码和去背景前景图像
    • 高精度处理头发/边缘等复杂场景
    • 4K超高清图像支持(20秒/张)
    • CUDA GPU加速(1080p图像仅需6秒)
    • 提供Python API便于系统集成

值得注意的是,该模型在DIS5k基准测试和22K专有数据集上训练,1.13GB的轻量化体积使其兼具高性能与部署便捷性。
