Recognition Fundamentals

How Image Recognition Works

Template Matching Process

Key Concepts

• Template: The reference image captured from UI components
• Threshold: Minimum similarity percentage for matches (0-100%)
• Search Region: Screen area to search within
• Confidence Score: How closely a found match resembles the template
• False Positives: Incorrect matches that meet threshold requirements
