BiRefNet-lite 针对移动 NPU 进行优化,实现 23.7 毫秒推理速度

一位独立研究人员已将 BiRefNet-lite 模型针对移动 NPU 进行了优化,在 Snapdragon 8 Elite Gen 5 上实现了 1024px 主体抠图的 23.7 毫秒推理时间。此优化涉及重大的图重写和架构更改,使模型能够完全在设备上运行,克服了原始模型的内存限制和性能瓶颈。结果的 int8 量化模型在关键基准测试中保持了高精度,与 fp32 版本非常接近,现在已开放权重并为 42 种不同的 Snapdragon 芯片进行了编译。 AI

影响 为移动应用实现设备端高分辨率图像分割,可能改善照片编辑和 AR 中的用户体验。
