Scans of film damage

Empty scans of 35mm film frames with artifacts. Emulsion: Lomochrome Purple Development process: C41 Scanner: Plustek OpticFilm 7600i Scanning software: Silverfast 9 Scanning DPI: 300 Scanned to 16-bit B&amp;W tiff and converted to JPG using Lightroom with no compression. We manually annotate individual artifacts in the scans with<br> bounding polygons, and classify each as dirt, dust, long hair, short hair or scratch. We extract each individual artifact, zero padded to square, to create a bank of isolated artifacts to sample from when generating new overlays. In total we have annotated 12135 artifacts across the 10 scanned frames. Annotations for each scan are included in JSON format, and can easily be converted to OpenCV contour format. <br>本数据集包含带有伪影的35mm胶片空白帧扫描件。 胶片乳剂：Lomochrome Purple 冲洗工艺：C41 扫描设备：Plustek OpticFilm 7600i 扫描软件：Silverfast 9 扫描分辨率：300 DPI 扫描源文件为16位黑白TIFF格式，后经Lightroom无压缩转换为JPG格式。 我们手动对扫描件中的各独立伪影进行标注：以边界多边形框选单帧伪影，并将其划分为污垢（dirt）、尘埃（dust）、长发（long hair）、短发（short hair）与划痕（scratch）五类。我们提取每一个独立伪影，通过零填充将其调整为正方形尺寸，以此构建孤立伪影样本库，用于生成新叠加层时的采样。 本次共在10帧扫描胶片中标注了12135个伪影。每帧扫描件的标注文件均以JSON格式提供，可便捷转换为OpenCV轮廓格式。
