🧪 Testing Manual Image / Video Analysis

This page explains how to test the manual image and manual video analysis modes.

  • For this test, single images (not videos) are a prerequisite.
  • The test image you must use is located in the DL_Track_US_example/tests/test_images_manual folder.
  • Both manual image analysis and manual video analysis use the same Python class (ManualAnalysis located in manual_tracing.py).
  • Therefore, testing one (manual image analysis) is sufficient.

Test Preparation

Before starting:

  • Make sure to use the correct image:
    DL_Track_US_example/tests/test_image_manual.
  • Click the Run button to start the analysis.

Reanalysing the Test Image

Follow these steps:

  1. Scale the image
  2. Follow the one-centimetre long scaling line shown on the left of the image.

  3. Scale the image accordingly.

  4. Draw Aponeuroses

  5. Redraw the superficial and deep aponeurosis extension lines.

  6. Measure Muscle Thickness

  7. Redraw the three vertical muscle thickness lines using one segment each.

  8. Trace Fascicles

  9. Redraw the three diagonal fascicle lines using three segments each.

  10. Measure Pennation Angles

  11. Redraw the three pennation angles using two segments each.

âš¡ Important:
Always select the correct Radiobutton corresponding to the parameter you are analyzing.

After reanalyzing all lines:

  • Click the Save Results button to save your analysis.

A new file will be created:

  • Manual_Results.xlsx inside the DL_Track_US_example/tests/test_image_manual folder.

Validating the Results

  • Open the newly created Manual_Results.xlsx file.
  • Compare the analysis results to the expected results shown below.

If the results are similar, DL_Track_US works properly for manual image and video analysis!
