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?
and this loop runs very hot, near a trillion operations per second in L1 cache, so you want to avoid any other overhead when possible, compute things ahead of time and so on. but the core algorithm is just this. the rest is engineering and optimizations on top of this.，更多细节参见PDF资料

“一脑一形”本身就是最难的部分。你把一个大脑练到能控制好单臂，让它知道怎么焊、怎么避障、怎么调整姿态，这80%以上的通用能力就已经解决了。我们判断，一旦攻克首个全量场景，跨本体的适配难度有望降低至10%左右。
