✂️ Remove Video Parts

In DL_Track_US you can remove parts of a video to:

  • Improve segmentation accuracy:
    Sometimes the superficial aponeurosis can be wrongly segmented if the skin or subcutaneous tissue is thick or highly echogenic.
    Cropping out the upper regions can avoid these errors.
  • Support data anonymization:
    Sensitive or identifying areas can be cropped to protect subject privacy.

✅ This is especially useful before running automated segmentation.

1. Accessing the Remove Video Parts Tool

  • Once the GUI is open, click on the Advanced Methods button.
