算子分层详情
ACL Pack 算子按授权等级分为三个层级。高层级包含低层级的全部算子。
层级概览
| 层级 | 算子族数 | 适用套餐 | 说明 |
|---|---|---|---|
| 核心 (Core) | 57 | 试用版 (1个示例)、Starter、Pro、Business、Enterprise | 基础图像处理 — 滤波、色彩转换、几何变换、算术运算、分析、绘图 |
| 进阶 (Advanced) | 100 | Pro、Business、Enterprise | 新增 DFT/FFT、HSV/Lab 色彩、高级滤波、特征检测、直方图分析、轮廓分析 |
| 完整 (Full) | 113 | Business、Enterprise | 标准完整库 — Business YUV remap、距离分析、全部特征套件 |
Trial 仅包含 1 个示例算子：
resize，输入固定 1920×1280，输出带水印。标准图片像素类型为
uint8_t、uint16_t和float。精确类型支持按算子和后端而定;int16_t、int64_t、double等辅助类型仅用于特定输出、累加器、几何或参数角色。

计数约定： 以上 113 行按标准文档算子族计数（同一算子的 CPP 与 NEON 实现合并为 1 行）。企业定制的
YUV_utilities*融合管线仅为可见性列出，不计入标准套餐数量。若按客户面可调用入口口径（含多图输入变体、核大小分派、独立交付的 CPP/NEON 对），Business 包暴露 163 个可调用入口。分层授权以算子族为单位 — Starter 层算子的所有变体均包含在 Starter 层中。[trial]标记表示该算子是 Trial 版包含的示例算子。
