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?

At the same time, the company’s weaknesses and growth pain points are equally prominent—and have become the central tests on its path to an IPO. First, control gaps in the franchising model are glaring. With franchised stores accounting for more than 95% of the network, quality control is extremely difficult. In 2024, the “worm incident” at a Beijing franchise store triggered a crisis of trust in the brand; related complaints on the Black Cat platform exceeded 380. Revenue at some outlets plunged by 30%. Meanwhile, in 2025 the ratio of newly opened to closed franchise stores deteriorated from 15:1 to 3:1. Franchisees’ payback periods averaged 13–20 months—and could be longer in top-tier cities due to intense competition. Waning franchisee enthusiasm directly undermines the stability of the company’s core source of revenue.
