MLKitObjectDetectionCommon Framework Reference

  • MLKObject represents an object detected within an image, providing information about its location and characteristics.

  • It includes properties like frame for object's location, labels for descriptive information (if enabled), and trackingID for identifying objects across frames.

  • The frame property defines a rectangle indicating the detected object's position relative to the image.

  • labels property provides an array of descriptive labels, but only when classification is enabled during detection.

  • trackingID offers a unique identifier for tracking the object over time, which can be null if tracking wasn't set up.
