Image context and/or feature-specific parameters.

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

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.

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. Optional. 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", "apparel", or "toys" should be specified.
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. For example, "(color = red OR color = blue) AND brand = Google" is acceptable, but not "(color = red OR brand = Google)" or "color: red".

WebDetectionParams

Parameters for web detection request.

JSON representation
{ "includeGeoResults": boolean }

Fields
includeGeoResults	boolean Whether to include results derived from the geo information in the image.
