Sets language hints. In most cases, an empty value yields the best results since it
enables automatic language detection. For languages based on the Latin alphabet,
setting language hints 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).
Each language code parameter typically consists of a BCP-47 identifier. See
//cloud.google.com/vision/docs/languages for more details.
Sets model type for cloud text recognition. The two model
SPARSE_MODEL and
DENSE_MODEL are different models, which could handle different text
densities in an image.
