Using Color

Color analysis in Brobot helps improve object detection accuracy by filtering matches based on color properties.

Color-Based Finding​

Brobot can use color information to:

  • Filter false positives
  • Identify specific UI elements by color
  • Handle dynamic content with consistent colors

Basic Color Matching​

ActionOptions colorFind = new ActionOptions.Builder()
    .setAction(ActionOptions.Action.FIND)
    .setColor(Color.RED)
    .setColorTolerance(50)
    .build();

Advanced Color Analysis​

Color Histograms​

Color histograms provide statistical analysis of color distribution in images.

Color Classification​

Brobot can classify regions based on dominant colors:

  • Primary color detection
  • Color clustering
  • Multi-color pattern matching

Examples​

Finding Red Buttons​

StateImageObject redButton = new StateImageObject.Builder()
    .withImage("button.png")
    .withColor(Color.RED)
    .build();

Color-Based State Validation​

State colorState = new State.Builder("COLOR_STATE")
    .withColorValidation(region -> 
        region.getDominantColor().equals(Color.BLUE))
    .build();

Best Practices​

  1. Use color as a secondary filter - Don't rely solely on color
  2. Account for display variations - Colors may vary across monitors
  3. Test under different lighting - Ambient light affects color perception
  4. Set appropriate tolerances - Too strict = misses, too loose = false positives
