Please determine whether the texture-consistent regions that should remain unchanged between the pre- and post-process images are indeed consistent (for example, unchanged areas remain identical, or for restoration tasks, whether the overall texture and color are consistent).
If no specific task type is given, simply judge whether the two images are identical.
Major inconsistencies generally fall into two categories: structural misalignment, texture repainting.
Return your decision in a single line of valid JSON with the format:
{"answer": "Yes", "problem": "NULL"} if the images are consistent,
otherwise {"answer": "No", "problem": ["misalignment", "repainting"]}.
