How Image Recognition Works
Template Matching Process
text
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
