Interface VisionAnalyzer<T>

All Superinterfaces:
AutoCloseable
All Known Implementing Classes:
BarcodeScanner, DocumentScanner, FaceDetector, ImageLabeler, PoseDetector, SelfieSegmenter, TextRecognizer
public interface VisionAnalyzer<T> extends AutoCloseable
Reusable, closable on-device analyzer for still images or camera frames. Implementations may retain native detectors and models between calls, so create one analyzer per stream/workflow and close it when finished. Backend creation, request scheduling, capability checks, and close are serialized so a concurrent close cannot leave a newly created backend attached after the analyzer has closed.

  • Method Summary

    Modifier and Type
    Method
    Description
    void
    close()
    Releases native detector/model resources; further processing fails.
    boolean
    isSupported()
    Tests the exact feature/backend pair configured for this analyzer.
    AsyncResource<T>
    process(VisionImage image)
    Starts one asynchronous analysis without uploading the image.

  • Method Details

    • isSupported

      boolean isSupported()
      Tests the exact feature/backend pair configured for this analyzer.
      Returns:
      true when the current target supports it

    • process

      AsyncResource<T> process(VisionImage image)
      Starts one asynchronous analysis without uploading the image.
      Parameters:
      image - encoded or raw input
      Returns:
      asynchronous typed result delivered on the EDT

    • close

      void close()
      Releases native detector/model resources; further processing fails.
