Hairline

A low, straight, dense hairline with no retreat at the temples.

ImageFacehairlineVersion 1

Judges the hairline and the hair directly behind it: height on the forehead, shape, density, and any recession at the temples. A hat, hood, or camera angle that hides the hairline leaves nothing to judge, and scores accordingly.

What it looks for

A hairline set low on the forehead
A straight or gently rounded front with full temples
Dense hair directly behind the hairline
No visible scalp or thinning at the front

Input

Send one image as a base64 data URL in image: PNG, JPEG, or WebP, at most 3 MiB (3,145,728 bytes) decoded. Text is optional context. A request with an image costs 10 units however many image formulas it names, so batch this one with others such as Jawline and Canthal Tilt, up to 8 per request.

The call returns noul, the probability from 0 to 1 that the answer is yes, and mogs, the verdict. The pass/fail boundary is set on the server and never returned. Use mogs as the decision and noul to rank.

POST /api/v1/mog

# Build the body in a file: a base64 image is too long for a shell argument.
# For a PNG or WebP file, change image/jpeg to image/png or image/webp.

  printf '{"formula":"hairline","image":"data:image/jpeg;base64,'
  base64 < photo.jpg | tr -d '\n'
  printf '"}'

# With the mogger skill installed, ask in plain words, for example:
#   Does ./photo.jpg mog on hairline?
# The skill base64-encodes the file in the shell, so the image
# never enters the model context, and runs:
score_image ./photo.jpg hairline | jq '.results'
