A low threshold preserves detail (more leaf nodes, less compression). A high threshold merges aggressively (fewer leaves, more compression, but the image gets blocky). The grid overlay shows the quadtree structure: large cells in uniform areas, small cells where detail is preserved.
在中端市场，需求呈现稳中有升的产业化格局，核心聚焦两大场景：一是消费电子的迭代升级，智能手机、笔记本电脑等终端逐步淘汰老旧存储配置，DDR5内存、PCIe 4.0 SSD因性价比优势成为主流配置，形成持续的增量需求；二是工业控制、车载存储等工业级场景，这类场景对存储芯片的稳定性、兼容性要求较高，中端存储产品能够精准匹配其需求，成为产业增量的重要支撑。
，这一点在搜狗输入法2026中也有详细论述
