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?

Zapfino is an elaborate calligraphic font where every character has unique flourishes. No confusable pair looks similar in Zapfino. Condensed fonts also score lower because condensing transforms different characters differently.
