✂️ Resize Video

In DL_Track_US you can resize a video so that only the selected region remains:

  • Improve segmentation accuracy:
    Resizing the video to focus on the muscle region can improve model performance by cropping out irrelevant background information.
  • Support data anonymization:
    Sensitive areas (e.g., patient IDs or other identifying marks) can be removed entirely by resizing.

✅ This is especially useful before running automated segmentation!

1. Accessing / Loading

  • Once the GUI is open, click on the Advanced Methods button.
  • In the Select Method dropdown, select Resize Video.
  • A separate Resize Video Window will pop up.

This process is similar to the remove video parts function. Have a look there if you are uncertain.

2. Loading the Video

  • Click the Load Video button.
  • Select the video file you want to resize.

After successfully loading the video:

  • Use the yellow slider to scroll through the video frames.
  • Click and drag with the left mouse button to select the part you want to keep.

Your result (after re-loading) will look like this:

3. Saving the Resized Video

  • Click the Browse button to select the output folder.
  • Then click Resize Video to crop and save the video.

Again, the process is similar to the remove video parts function. Have a look there if you are uncertain.

🧠 Tip:
Resizing the video can speed up the analysis, reduce errors, and protect privacy
— especially in clinical settings or publications. However, we did not include resized images during the training process.
