Improved human silhouette overlay to better center the face and make it larger for optimal FaceID recognition.
Changes:
Face positioning:
- Moved face center from cy=120 to cy=150 (centered vertically)
- Face now occupies middle of frame instead of upper third
- Eyes align with horizontal center line at y=150
- Better balance between head and body in frame
Face size increase:
- Increased head ellipse from rx=75,ry=95 to rx=90,ry=115
- ~20% larger face area for better recognition
- More prominent facial features in final crop
- Improved face-to-frame ratio (70-80% coverage)
Body proportions updated:
- Neck: y=250 to y=285 (moved down)
- Shoulders: y=230 to y=285 (centered below face)
- Torso extends to bottom of frame
- More natural body proportions
Guide lines adjusted:
- Eye-level line: y=120 → y=150 (center of frame)
- Shoulder line: y=230 → y=285 (below center)
- Vertical center line unchanged (x=150)
UI text updates:
- Instructions emphasize face centering
- 'Расположите глаза на центральной линии'
- 'Голова занимает верхнюю половину фото'
- Changed bottom label from 'Пояс' to 'Низ кадра'
Benefits:
