public final class ImageLabel

Object
ImageLabel

Portable ranked image-classification label. Confidence is normalized to 0..1. The numeric index is a backend/model class index and should not be treated as stable across different backends; portable code should prefer the text label.

Constructors

`public ImageLabel(String text, float confidence, int index)`	Creates a label without backend metadata.
`public ImageLabel(String text, float confidence, int index, VisionMetadata metadata)`	Creates a label with backend diagnostics.

Methods

`public` `String getText()`
`public float getConfidence()`
`public int getIndex()`	Returns the backend/model class index when the selected classifier exposes one.
`public` `VisionMetadata getMetadata()`

Constructor details

ImageLabel

public ImageLabel(String text, float confidence, int index)

Creates a label without backend metadata.

Parameters

text String: normalized label text
confidence float: provider confidence, normally from zero to one
index int: provider label index, or a negative value when unavailable

ImageLabel

public ImageLabel(String text, float confidence, int index, VisionMetadata metadata)

Creates a label with backend diagnostics.

Parameters

text String: normalized label text
confidence float: provider confidence, normally from zero to one
index int: provider label index, or a negative value when unavailable
metadata VisionMetadata: backend details, or null

Method details

getText

public String getText()

Returns

human-readable class label

getConfidence

public float getConfidence()

Returns

classification confidence in the range 0..1

getIndex

public int getIndex()

Returns the backend/model class index when the selected classifier exposes one. The index identifies a class in that specific model; it is not portable across models or backends. Apple Vision does not expose a numeric class index and therefore returns -1. Prefer getText() when writing backend-independent application logic.

Returns

backend/model class index, or -1 when unavailable

getMetadata

public VisionMetadata getMetadata()

Returns

backend metadata, or null when manually constructed
