NULLSCAN is a non-compromise, 100% offline mobile scanner. By combining the speed of ML Kit with the raw power of OpenCV, it delivers a hybrid vision pipeline that handles complex document scanning tasks locally on your device.
零·描 是一款拒绝妥协的全离线移动端扫描工具。它完美融合了 ML Kit 的快速感知与 OpenCV 的硬核图像处理能力，构建了一套混合视觉流水线。所有像素级的计算均在本地完成，真正做到零延迟、零泄露。
- Aether Lens: Real-time edge detection via ML Kit. (基于以太透镜的秒级边缘捕捉)
- OpenCV Engine: Advanced perspective transformation and image normalization. (利用 OpenCV 实现精准的透视变换与拉直)
- Lazarus Filters: Custom CV algorithms to remove noise and restore document clarity. (自研 CV 算法，深度去噪并复活陈旧文档)
- Air-gapped by Design: The app does not even request the
INTERNETpermission. (原生不申请网络权限，实现物理级隔离) - Zero-Metadata: We process images, not your identity. (我们只处理像素，不触碰元数据)
