ImageContext

Image context and/or feature-specific parameters.

JSON representation 
{
  "latLongRect": {
    object (LatLongRect)
  },
  "languageHints": [
    string
  ],
  "cropHintsParams": {
    object (CropHintsParams)
  },
  "productSearchParams": {
    object (ProductSearchParams)
  },
  "webDetectionParams": {
    object (WebDetectionParams)
  },
  "textDetectionParams": {
    object (TextDetectionParams)
  }
}
Fields
latLongRect

object (LatLongRect)

Not used.
languageHints[]

string

List of languages to use for TEXT_DETECTION. In most cases, an empty value yields the best results since it enables automatic language detection. For languages based on the Latin alphabet, setting languageHints is not needed. In rare cases, when the language of the text in the image is known, setting a hint will help get better results (although it will be a significant hindrance if the hint is wrong). Text detection returns an error if one or more of the specified languages is not one of the supported languages.
cropHintsParams

object (CropHintsParams)

Parameters for crop hints annotation request.
productSearchParams

object (ProductSearchParams)

Parameters for product search.
webDetectionParams

object (WebDetectionParams)

Parameters for web detection.
textDetectionParams

object (TextDetectionParams)

Parameters for text detection and document text detection.

LatLongRect

Rectangle determined by min and max LatLng pairs.

JSON representation 
{
  "minLatLng": {
    object (LatLng)
  },
  "maxLatLng": {
    object (LatLng)
  }
}
Fields
minLatLng

object (LatLng)

Min lat/long pair.
maxLatLng

object (LatLng)

Max lat/long pair.

CropHintsParams

Parameters for crop hints annotation request.

JSON representation 
{
  "aspectRatios": [
    number
  ]
}
Fields
aspectRatios[]

number

Aspect ratios in floats, representing the ratio of the width to the height of the image. For example, if the desired aspect ratio is 4/3, the corresponding float value should be 1.33333. If not specified, the best possible crop is returned. The number of provided aspect ratios is limited to a maximum of 16; any aspect ratios provided after the 16th are ignored.

ProductSearchParams

Parameters for a product search request.

JSON representation 
{
  "boundingPoly": {
    object (BoundingPoly)
  },
  "productSet": string,
  "productCategories": [
    string
  ],
  "filter": string
}
Fields
boundingPoly

object (BoundingPoly)

The bounding polygon around the area of interest in the image. If it is not specified, system discretion will be applied.
productSet

string

The resource name of a ProductSet to be searched for similar images.

Format is: projects/PROJECT_ID/locations/LOC_ID/productSets/PRODUCT_SET_ID.
productCategories[]

string

The list of product categories to search in. Currently, we only consider the first category, and either "homegoods-v2", "apparel-v2", "toys-v2", "packagedgoods-v1", or "general-v1" should be specified. The legacy categories "homegoods", "apparel", and "toys" are still supported but will be deprecated. For new products, please use "homegoods-v2", "apparel-v2", or "toys-v2" for better product search accuracy. It is recommended to migrate existing products to these categories as well.
filter

string

The filtering expression. This can be used to restrict search results based on Product labels. We currently support an AND of OR of key-value expressions, where each expression within an OR must have the same key. An '=' should be used to connect the key and value.

For example, "(color = red OR color = blue) AND brand = Google" is acceptable, but "(color = red OR brand = Google)" is not acceptable. "color: red" is not acceptable because it uses a ':' instead of an '='.

WebDetectionParams

Parameters for web detection request.

JSON representation 
{
  "includeGeoResults": boolean
}
Fields
includeGeoResults
(deprecated)

boolean

This field has no effect on results.

TextDetectionParams

Parameters for text detections. This is used to control TEXT_DETECTION and DOCUMENT_TEXT_DETECTION features.

JSON representation 
{
  "enableTextDetectionConfidenceScore": boolean,
  "advancedOcrOptions": [
    string
  ]
}
Fields
enableTextDetectionConfidenceScore

boolean

By default, Cloud Vision API only includes confidence score for DOCUMENT_TEXT_DETECTION result. Set the flag to true to include confidence score for TEXT_DETECTION as well.
advancedOcrOptions[]

string

A list of advanced OCR options to further fine-tune OCR behavior. Current valid values are:

  • legacyLayout: a heuristics layout detection algorithm, which serves as an alternative to the current ML-based layout detection algorithm. Customers can choose the best suitable layout algorithm based on their situation.
