Pet Portrait Generation On-App AI

Pet Portrait Generation Pet Portrait Generation

Feature Introduction

This function uses AI technology to intelligently merge preset fun theme templates with user-uploaded images, achieving one-click, zero-barrier pet fun editing. The solution requires no token consumption and supports instant generation from photos, allowing users to experience the joy of free creation.

Process Description

1. Resource Preparation Phase

Cloud Resource Library
  • Model Repository
    • Pre-trained AI model storage (e.g., subject detection, dynamic center point adaptation, etc.)
    • Supports model downloads to local or cloud inference environment
  • Template Material Library
    • Stores foreground templates, background materials, etc.
    • Supports template downloads or template configuration retrieval

2. Input Processing Phase

  • Image Files
    • User original photo upload
    • Supports image recognition (people/pet detection)
  • Media Files
    • Media input (currently only supports static images)
    • Supports media synthesis preprocessing

3. On-APP AI Processing Phase

  • On-App AI Processing Flow
    • Real-time processing combining downloaded models and templates
    • Typical operations:
      • Portrait segmentation
      • Style rendering
      • Background composition
  • Strategy Optimization
    • Automatically adjusts subject centering based on subject coordinates in the image

4. Output Phase

  • Generate AI portrait images/videos
  • Support saving to phone local gallery
