    comfyui-segs-profile

    A tiny ComfyUI custom node that detects whether a face is in profile using SEGS eye detections.

    It expects a single SEGS input that may contain segments labeled left_eye and right_eye (as produced by many SEGS/Impact pipelines). It picks the largest segment for each eye, computes the area ratio, and returns a boolean is_profile.

    If one of the eyes is missing, the node returns is_profile = True and eye_ratio = 0.0.

    Node

    Name in ComfyUI: SEGS Is Profile (eye_ratio)

    Inputs

    • segs (SEGS): should contain segments with labels left_eye and right_eye (if detected)
    • threshold (FLOAT): default 2.0
      is_profile = eye_ratio > threshold

    Outputs

    • is_profile (BOOLEAN)
    • eye_ratio (FLOAT)
    • debug (STRING) – convenient for previewing values

    Algorithm

    1. Extract segments list from SEGS
    2. Pick the largest left_eye and right_eye by bbox area
    3. Compute area = (x2-x1) * (y2-y1)
    4. If one eye is missing: is_profile=True, eye_ratio=0.0
    5. Else: eye_ratio = max(area_left, area_right) / (min(area_left, area_right) + eps)
    6. Compare with threshold

    Installation
