1. Introduction

Overview
HUAWEI HiAI is an open artificial intelligence (AI) capability platform for smart devices, which adopts a "chip-device-cloud" architecture, opening up chip, app, and service capabilities for a fully intelligent ecosystem. This assists you in delivering an optimal smart app experience for users, by fully leveraging Huawei's powerful AI processing capabilities.
In order to open up app capabilities, HUAWEI HiAI Engine provides a wide range of AI capabilities that can be integrated into apps. Image category labeling, one such AI capability, empowers apps to:
- Accurately identify 100 categories of objects, scenes, and actions, which can be applied in album categorization, smart image enhancement, voice and text image searches, and user preference labeling.
