中文译文
严格基于所提供参考图像进行超高分辨率 4K 增强。绝对忠实于原始面部解剖结构、比例和身份特征。保留表情、目光、姿态、相机角度、构图和透视，零偏差。服装、头发、皮肤和背景元素必须在结构、位置和设计上保持不变。以自然真实感恢复细粒度细节。增强毛孔、细纹、发丝、睫毛、织物纹理、接缝和材质边缘，不得引入风格化。精确保留原始色彩科学、白平衡和影调关系，与拍摄时完全一致。光照方向、强度、对比度和阴影表现必须与源图像精确匹配，仅提升清晰度并扩展动态范围。不重新打光，不重塑形体。去除任何颗粒。应用受控锐化和高频细节重建。去除压缩伪影和噪点，同时保留真实纹理。不平滑，不塑料皮肤，不人工光泽。面部特征必须在整个图像中保持一致，解剖结构连贯，边缘干净稳定。负面约束：不扭曲，不面部漂移，不添加或缺失解剖结构，不改变手部，不变形，不透视偏移，无文字或图形，不幻觉细节，不风格化渲染。输出必须呈现为与参考完全一致的真实感、照片级写实放大，只是更清晰、更锐利、分辨率更高。
English original
"Ultra-high-resolution 4K enhancement based strictly on the provided reference image. Absolute fidelity to original facial anatomy, proportions, and identity. Preserve expression, gaze, pose, camera angle, framing, and perspective with zero deviation. Clothing, hair, skin, and background elements must remain unchanged in structure, placement, and design. Recover fine-grain detail with natural realism. Enhance pores, fine lines, hair strands, eyelashes, fabric weave, seams, and material edges without introducing stylization. Maintain original color science, white balance, and tonal relationships exactly as captured. Lighting direction, intensity, contrast, and shadow behavior must match the source image precisely, with only improved clarity and expanded dynamic range. No relighting, no reshaping. Remove any grain. Apply controlled sharpening and high-frequency detail reconstruction. Remove compression artifacts and noise while retaining authentic texture. No smoothing, no plastic skin, no artificial gloss. Facial features must remain consistent across the entire image with coherent anatomy and clean, stable edges. Negative constraints: no warping, no facial drift, no added or missing anatomy, no altered hands, no distortions, no perspective shift, no text or graphics, no hallucinated detail, no stylized rendering. Output must read as a true-to-life, photorealistic upscale that matches the reference exactly, only clearer, sharper, and higher resolution."
