image_remove_background_mapper#

Mapper to remove the background of images.

This operator processes each image in the sample, removing its background. It uses the rembg library to perform the background removal. If alpha_matting is enabled, it applies alpha matting with specified thresholds and erosion size. The resulting images are saved in PNG format. The bgcolor parameter can be set to specify a custom background color for the cutout image. The processed images are stored in the directory specified by save_dir, or in the same directory as the input files if save_dir is not provided. The source_file field in the sample is updated to reflect the new file paths.

将图像的背景移除。

此算子处理样本中的每张图像，移除其背景。它使用 rembg 库来执行背景移除。如果启用了 alpha_matting，则应用带有指定阈值和腐蚀大小的 alpha 修边。生成的图像以 PNG 格式保存。可以通过设置 bgcolor 参数来指定剪切图像的自定义背景色。处理后的图像存储在由 save_dir 指定的目录中，如果没有提供 save_dir，则存储在与输入文件相同的目录中。样本中的 source_file 字段会更新以反映新的文件路径。
