Hi Andrew,
It is my understanding that you want more information regarding image segmentation of scanned documents. To perform image segmentation on scanned documents, you can perform the following steps:
- Preprocess the loaded image by converting it to grayscale, and apply thresholding to convert the image to binary format
- Perform image segmentation based on pixel intensity and perform morphological operations like “imfill”, “imdilate”, etc to clean up the binary image.
- To identify the dark regions, create a mask for the same in the grayscale image, and display the regions as potential text area.
For more resources on performing image segmentation on scanned document images, refer the following links:

- Segment and read text in image - https://www.mathworks.com/help/vision/ug/automatically-detect-and-recognize-text-in-natural-images.html
Hope this helps!
