Feature

The type of Google Cloud Vision API detection to perform, and the maximum number of results to return for that type. Multiple Feature objects can be specified in the features list.

Fields
type

enum(Type)

The feature type.

maxResults

number

Maximum number of results of this type. Does not apply to TEXT_DETECTION, DOCUMENT_TEXT_DETECTION, or CROP_HINTS.

model

string

Model to use for the feature. Supported values: "builtin/stable" (the default if unset) and "builtin/latest".

Type

Type of Google Cloud Vision API feature to be extracted.

Enums
TYPE_UNSPECIFIED Unspecified feature type.
FACE_DETECTION Run face detection.
LANDMARK_DETECTION Run landmark detection.
LOGO_DETECTION Run logo detection.
LABEL_DETECTION Run label detection.
TEXT_DETECTION Run text detection / optical character recognition (OCR). Text detection is optimized for areas of text within a larger image; if the image is a document, use DOCUMENT_TEXT_DETECTION instead.
DOCUMENT_TEXT_DETECTION Run dense text document OCR. Takes precedence when both DOCUMENT_TEXT_DETECTION and TEXT_DETECTION are present.
SAFE_SEARCH_DETECTION Run Safe Search to detect potentially unsafe or undesirable content.
IMAGE_PROPERTIES Compute a set of image properties, such as the image's dominant colors.
CROP_HINTS Run crop hints.
WEB_DETECTION Run web detection.
CUSTOM_LABEL_DETECTION Run custom label detection.
OBJECT_LOCALIZATION Run localizer for object detection.
IMAGE_QUALITY Run quality scorer.
OBJECT_ATTRIBUTES Compute attributes of objects detected in the image. Four domains of objects are supported. Please select via Feature.model (required): "builtin/apparel", "builtin/car", "builtin/food" or "builtin/wildlife".
QUALITY_OPTIMIZATION Run quality optimization algorithms. There are three types of operations: COMPRESSION, ENHANCEMENT and QUALITY_SCORE. COMPRESSION and ENHANCEMENT parameters, and QUALITY_SCORE model choice can are specified in imageContext.quality_optimization_params.
BARCODE_DETECTION Run barcode detection and recognition.
DOCUMENT_PARSING Run document parsing algorithms to extract structured data such as tables and forms. The results are found in fullTextAnnotation -> page -> block with type either TABLE for tables or KEY_VALUE_PAIR for key-value pairs in forms.
