DermaCheck Temporal Pairs Dataset

Dataset Description

Synthetic temporal image pairs for training MedGemma to detect changes in dermatoscopic images over time.

Created for: MedGemma Impact Challenge 2026 - Novel Task Prize (temporal change detection)

Dataset Statistics

Total pairs: 900
Train: 630 pairs (70.0%)
Validation: 135 pairs (15.0%)
Test: 135 pairs (15.0%)

Generation Methods

Controlled Augmentation (~50%): Original HAM10000 images augmented to simulate temporal evolution

Size increase: 10-30%
Border irregularity: Elastic transforms
Color variation: HSV adjustments
Based on clinical research: melanoma evolution patterns

Natural Pairing (~50%): Similar lesions from HAM10000 matched as temporal proxies

Feature-based similarity matching
Cosine similarity range: [0.6, 0.85]
Same diagnosis category (melanoma focus)

Unchanged Pairs (~15%): Negative examples for balanced training

Same image duplicated as before/after
Label: 0 (no change)

Dataset Structure

Each example contains:

image_before: PIL Image (before timepoint)
image_after: PIL Image (after timepoint)
text_prompt: ABCDE-focused change detection question
label: 0 (no change) or 1 (change detected)
change_description: Educational explanation of changes
method: Generation method (controlled_augmentation, natural_pairing, unchanged)
pair_id: Unique identifier
