-
Scratch-removal: Partial-convolution inpainting (NVIDIA’s gated conv) trained on 50 k artificially scratched vintage photos.
-
Colourisation: Dual-branch GAN – one branch predicts luminance, the other chrominance – enforces historical palette via classifier feedback (ResNet-18 pretrained on 1940s Kodachrome scans).
-
Motion: First-order motion model trained on 8 k high-fps portrait videos; generates 2.5 s 30 fps loop from single image.
Ethics & Rights
We embed an invisible watermark (DCT-based) that survives Instagram recompression; proves provenance if deep-fake questions arise. Auto-purge: container spins up, processes, writes S3 presigned URL, schedules Lambda delete after 60 min—user can shorten to 0 via API.

Performance Notes
Inpainting runs on GPU clusters; average job latency 42 s. Motion generation is CPU-fallback to keep costs low; still <3 min end-to-end.

划痕去除：使用 NVIDIA 的门控卷积进行部分卷积图像修复，该模型在 5 万张人工添加划痕的老照片上进行训练。
着色：双分支 GAN——一个分支预测亮度，另一个分支预测色度——通过分类器反馈强制执行历史调色板（ResNet-18，在 20 世纪 40 年代的柯达彩色胶片扫描件上预训练）。
运动：使用 8K 高帧率人像视频训练的一阶运动模型；从单张图像生成 2.5 秒、30 帧/秒的循环视频。
伦理与权利
我们嵌入了一个不可见的水印（基于 DCT），该水印在 Instagram 重新压缩后仍然存在；如果出现深度伪造问题，该水印可以证明图像的来源。自动清除：容器启动、处理、写入 S3 预签名 URL，并在 60 分钟后安排 Lambda 函数删除——用户可以通过 API 将清除时间缩短至 0。
性能说明
图像修复在 GPU 集群上运行；平均作业延迟为 42 秒。动态效果生成采用 CPU 回退机制以降低成本；端到端耗时仍小于 3 分钟。
