An image analysis request that finds and recognizes text in an image.

By default, a text recognition request first locates all possible glyphs or characters in the input image, then analyzes each string. To specify or limit the languages sought in the request, set the recognitionLanguages property to an array containing the names of the languages of text you'd like to recognize. Vision returns the result of this request in a VNRecognizedTextObservationMBS object.

Available on MacOS 10.15.
