When managing large photo libraries, whether for student ID cards, faculty directories, or multi-platform digital assets, manual cropping becomes a major bottleneck. Re-centering and framing individual portraits by hand introduces inconsistency in scale, head placement, and aspect ratios. To solve this, developing an automated framing system designed to generate a complete suite of standard headshots and portrait variations from a single, full-body source image . 1. The Core Geometric Model: H -Based Padding The precision of the automated framing relies on establishing the subject's head height (H) as the fundamental unit of measurement. Key Framing Rules: Head Measurement (H): Vertical distance from the top of the skull to the base of the chin. Top Clearance: A minimum buffer of H above the head. Lateral Clearance: A minimum buffer of H extending horizontally beyond the arms and torso. Bottom Clearance: A minimum buffer of H under the feet. By capturing or uploadin...
