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?
The drawback to the Sofort 2 is that it’s twice the price of the Evo. It’s challenging to recommend at $399, as most people would likely consider the differences between the two cameras relatively minor. The Leica user interface is easier to navigate, though, and I appreciate the included lens cap and extended two-year warranty. I also appreciate that it lets you print photos taken with other Leica cameras via the companion app — a nice perk for Leica fans. Nonetheless, I don’t think those perks are enough to justify spending nearly $200 more.，更多细节参见快连下载-Letsvpn下载
