About 照片修复
Last updated: May 2026
OptiPix 照片修复是用于让旧的、损坏的或褪色的照片重焕生机的完整流程 - 并且它完全在您的浏览器中运行。修复工作流程将引导您完成修复（自动检测划痕和灰尘，然后进行修复）、增强（自动色阶、CLAHE 局部对比度、去除暖色调发黄）和最终锐化。去黄工具可检测高光中占主导地位的暖色调，并将白平衡移至中性，从而消除数十年的褪色。划痕检测器使用形态学操作来查找细小的损坏线条，并通过修复算法填充它们。手动画笔可让您针对性地修复额外的损坏区域。污点去除器可查找孤立的亮/暗像素，并用其邻域中值替换它们。前后对比滑块可让您查看您的工作。支持批量处理和 HEIC 输入。所有操作均在本地使用 HTML Canvas 像素操作计算 - 非常适合修复家庭照片、扫描的底片和旧打印件，无需将任何内容上传到第三方服务。
How It Works
修复流程作为 Canvas 像素操作运行：形态学划痕检测、基于邻域的修复、孤立像素污点去除、直方图拉伸（自动色阶）、CLAHE 局部对比度、主色调白平衡校正（去黄）以及可选的锐化通道以完成。
