Digital Light & Color

Use Case
User works with a collection of photos representing full-page layouts—such as scanned publications or photographs of photo album pages. Each page contains multiple embedded images.

Workflow involves:

• Applying global transformations to the entire page (e.g., rotation, color correction, perspective adjustment).
• Automatically or manually extracting each embedded image from the layout.
• Applying a custom set of transformations to each extracted image individually.

Note: Extracted images may originate from cropping or geometric warp transformations.

Desired Capabilities

• Automatic Sub-Image Detection as a Transformation Node
  Introduce a new transformation type: "Detect Embedded Images", which identifies and isolates individual images within a page layout.
  This transformation would iterate over all detected sub-images, treating each as a separate unit for downstream processing.
• User-Guided Iteration and Control in the Transformation Tree
  Enable manual intervention at a designated breakpoint in the transformation tree:
  • User can manually crop or warp to define a sub-image.
  • After writing the processed image to file, provide a "Loop" or "Go Back" node that lets the user:
    • Continue extracting and processing additional sub-images from the same page.
    • Or proceed to the next page in the batch.
  This allows flexible, semi-automated workflows combining automatic detection with manual refinement.
