人物の背後を白背景にする

Isolate only the main person in the reference photo. Keep their visible body, hair, clothing and worn accessories. Remove every other person and every non-person object, including chairs, armchairs, seats, backrests, headrests, armrests, furniture, cushions, equipment and objects held in the hands. A chair or other object must be removed even when the person is sitting on it, leaning against it, touching it, or when it closely follows the outline of their head, hair, shoulders or clothing. Do not include any part of a chair or other surrounding object in the person cutout. Make all areas outside the person and all visible gaps between their body parts fully transparent. Preserve the exact identity, facial features, expression, skin texture, hair, clothing, body pose and natural outlines. Do not beautify, retouch or regenerate the face, and do not invent hidden or cropped body parts. Keep the original framing and orientation. Return only the person on a fully transparent background, with clean natural edges and no shadows or solid background.
