 * SEGSDetailer - Performs detailed work on SEGS without pasting it back onto the original image.
 * SEGSPaste - Pastes the results of SEGS onto the original image.
 * SEGSPreview - Provides a preview of SEGS.
+   * This option is used to preview the improved image through ```SEGSDetailer``` before merging it into the original. Prior to going through ```SEGSDetailer```, SEGS only contains mask information without image information. If fallback_image_opt is connected to the original image, SEGS without image information will generate a preview using the original image. However, if SEGS already contains image information, fallback_image_opt will be ignored. 
 
 * Pipe nodes
    * ToDetailerPipe, FromDetailerPipe - These nodes are used to bundle multiple inputs used in the detailer, such as models and vae, ..., into a single DETAILER_PIPE or extract the elements that are bundled in the DETAILER_PIPE.
