Glabellar Lines

About Parameter

Glabellar lines, often called frown lines, are the small vertical wrinkles that appear between your eyebrows. They form when the muscles that pull your eyebrows together move repeatedly — for example, when you frown or concentrate. At first, these lines show up only during facial expressions, but over time, they can become visible even when your face is relaxed.

Features

1. Works with frontal side facial images (because glabellar lines are visible on frontal images, which is why we require frontal images for reliable analysis).

2. Evaluates severity (grade) of glabellar lines

3. Separates and segments deep and fine lines

Output

1. Grade from 1 to 5.

2. Vector mask for deep lines.

3. Vector mask for fines lines.

4. Vector mask containing both deep lines and fine lines.

5. Algorithm-assigned skin condition tag (Great, Good, Average, Poor).

6. Amount of lines.

7. Amount of deep lines.

8. Amount of fine lines.

9. Length of lines relative to length of the forehead.

10. Length of deep lines relative to length of the forehead.

11. Length of fine lines relative to length of the forehead.

Note: When a single line has varying severity (containing both deep and fine sections), it is categorized as a one deep line rather than a fine line.

Grades Description

Severity assessment based on the depth of the most prominent wrinkle

Grade value	Description	Tags
1	No visible wrinkles	Great
2	Fine, shallow wrinkle that is barely noticeable	Good
3	Prominent wrinkle that is deeper and wider with a visible base	Average
4	Deep, clearly defined wrinkle with raised borders on both sides (slightly or moderately pronounced)	Poor
5	Deep wrinkle with prominent raised borders, creating the impression of "carved" skin in this area	Poor
