9月10日，罗永浩在微博上发文称西贝餐饮“几乎全都是预制菜”，这一说法引发网友广泛关注与讨论，“罗永浩吐槽西贝”相关内容登上热搜，翌日西贝创始人、董事长贾国龙在新闻发布会上表示“西贝不是预制菜”，并宣布推出“罗永浩菜单”，并开放全国门店后厨给大众参观，并扬言要起诉罗永浩。受到舆论风波的影响，西贝餐饮自9月10日起的营业额出现连续下降，9月12日起每日的营业额预计减少200—300万元。9月14日晚，贾国龙在微信称罗永浩是“网络黑嘴、网络黑社会”。9月15日中午，西贝官方发布了书面致歉信。罗永浩表示决定放弃追究西贝。

SSIM (Structural Similarity Index Measure) compares two images by evaluating luminance, contrast, and structural patterns across local windows. It returns a score from -1 to 1: 1.0 means the images are pixel-identical, 0 means no structural correlation, and negative values mean the images are anti-correlated (less alike than random noise). For glyph comparison, it answers the question: do these two rendered characters share the same visual structure?
