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?
据TheElec，三星电子最早将在今年3月停止在华城园区12号生产线制造2D NAND闪存，该企业的2D NAND闪存时代也将随之正式结束。三星电子早在2013年就实现了3D NAND (V-NAND) 的量产，不过三星还是保留了小规模的2D NAND产能以应对特殊利基市场的需求。华城12号生产线未来将服务于1c nm DRAM内存制造，负责后端的金属布线和表面处理工艺。（财联社）
