使用 GPU 加速（处理大量图片）

    """使用 GPU 加速批量色彩调整"""

        transforms.ColorJitter(
            brightness=brightness-1,
            contrast=contrast-1,
            saturation=saturation-1,
            hue=hue
        ),
    ])

            # 应用转换
            adjusted = transform(img)
            # 保存
            output_path = os.path.join(output_folder, filename)
            adjusted.save(output_path)
            print(f"已处理: {filename}")
