“政绩观问题是一个根本性问题，关乎立党为公、执政为民。”政绩为谁而树、树什么样的政绩、靠什么树政绩，是初心之问、使命之问，也是时代之问、实践之问。

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?
