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?

We’re expecting to see a new MacBook Air next week, along with updated 14- and 16-inch MacBook Pros. It's believed that the M5 Pro and M5 Max will debut in the higher-end devices. Apple may also be cooking up an entry-level MacBook that'll be available in an iMac-style array of bright colorways. New iPads and the iPhone 17e could well be in the hopper too.
