Operator Tiers

ACL Pack operators are grouped into three tiers based on your license. Each higher tier includes all operators from the previous tier.

Tier Overview

Tier	Operator families	Plans	Description
Core	57	Trial (1 sample), Starter, Pro, Business, Enterprise	Essential image processing — filters, color conversion, geometric transforms, arithmetic, analysis, drawing
Advanced	100	Pro, Business, Enterprise	Adds DFT/FFT, HSV/Lab color, advanced filters, feature detection, contour analysis, histogram analysis
Full	113	Business, Enterprise	Complete standard library — Business YUV remap, distance analysis, full feature suite

Trial limits to 1 sample operator: resize, at fixed 1920×1280 resolution with a watermark on the output.

Standard image pixel types are uint8_t, uint16_t, and float. Exact type support is operator- and backend-dependent; auxiliary types such as int16_t, int64_t, and double are used only in specific output, accumulator, geometry, or parameter roles.

resizeYUV / rotateYUV are NEON-only atomic YUV-format operations (NV21/NV12/YV12/YUV444). YUV_utilities / YUV_utilities_float are CPP-only fused pipelines (resize + rotate + YUV→RGB in one pass) delivered as Enterprise customization outside the standard Core / Advanced / Full package counts.

Counting convention: The 113 category rows above count each standard documented operator family once (CPP and NEON variants of the same operator share one row). Enterprise-custom YUV_utilities* fused pipelines are listed for visibility but are not part of the standard package counts. Counting customer-facing callable entries — including N-image variants, kernel-size dispatchers, and CPP/NEON pairs that ship as separate callable functions — the Business package exposes 163 callable entries. Tier licensing is per-operator family — all variants of a Starter-tier operator are included in the Starter tier. The [trial] marker indicates the operator is the sample operator included in the Trial edition.
