Lower Limb Data Addition

Overview

This pull request adds the complete extracted and organized data from the Bone Box (Lower Limb) PowerPoint presentation to the data branch.

Data Included

Boneset Structure

• lower_limb.json: Main boneset definition containing 5 bones

Bones (5 total)

• Femur (with 13 subbones)
• Patella (with 2 subbones)
• Tibia (with 8 subbones)
• Fibula (with 8 subbones)
• Foot (with 10 subbones)

Subbones (40+ files)

Individual JSON files for each anatomical subpart with standardized naming (snake_case IDs).

Descriptions (45+ files)

• Individual description files for each bone and subbone
• Includes detailed anatomical descriptions
• Contains muscle attachment information
• Properly formatted and cleaned

Images (120+ files)

• Extracted from 57 slides of the PowerPoint
• Organized by bone with sequential numbering
• Files named: {bone_id}_image{number}.{png|jpeg}

Annotations

• Colored Regions (4 files): Anatomical overlay data for femur, tibia, fibula, and foot
• Text Labels (4 files): Text annotation data for femur, patella, tibia, and fibula

• The data_extraction folder should not be committed
• The images should not all be named after just the femur. You should look through the PowerPoint and verify which bone the image is a picture of based on the slides. You can also go ahead and get rid of duplicate images.
• The femur and fibula both have "head" and "shaft" subbones. In order for these to have unique IDs, I think they should be renamed to "femur_head", "fibula_head", "femur_shaft", and "fibula_shaft". These changes would have to be made in bones/femur.json, bones/fibula.json, and in the subbones/ directory. It also looks like there are only descriptions (in descriptions/ for the femur head and femur shaft, not for the fibula head and fibula shaft.
• The descriptions generally need to be cleaned up by looking through the PowerPoints and making sure the description arrays only contain lines of text in the actual descriptions on each slide.
• The text labels weren't extracted, which is fine, since the script needed to be improved. I've recently made improvements to the text extraction script; you can update your main branch to see the changes to the new extract_text_labels.py which should better extract the text labels.

Since they have their own dedicated slides in the PowerPoint, the following should also be their own dedicated subbones:

[
  "1st_metatarsal",
  "proximal_phalanx",
  "distal_phalanx",
  "2nd-5th_metatarsals"
  "phalanges"
]

[leandrumartin]

This is the description for the "1st metatarsal." The filename, name, and ID should be adjusted to match.

This is the description for the "2nd-5th metatarsals." The filename, name, and ID should be adjusted to match.

This file should not be committed.

Slight addendum to my previous comment about removing duplicate images: To link a boneset, bone, or subbone to a specific image, you can (as described in the documentation for cleaning the output of Extract_Bone_Descriptions.py) include that image filename in the "images" field. So duplicate images are not needed at all.
