What Galacticos Can Do

Image Classification
Identify tissue type across 12 dermatological classes with per-class probability scoring and confidence levels.
Tissue Segmentation
4 visualization modes — binary mask, overlay, contour lines, and probability heatmap — powered by nnU-Net.
AI Image Validation
Gemini-powered pre-screening ensures only valid medical images are analyzed, rejecting non-medical uploads.
Drag & Drop Upload
Upload PNG, JPG, or BMP biopsy images with instant preview and file validation.
Analysis History
Review and restore previous analysis results. Click any history entry to reload its full results.
Export Results
Download complete analysis results — including segmentation overlays — as PNG images.
