    VNRecognizeTextRequestRevision2 supports English, Chinese, Portuguese, French, Italian, German and Spanish in the accurate recognition level. The fast recognition level supports English, Portuguese, French, Italian, German and Spanish. Best practice is to use supportedRecognitionLanguagesForTextRecognitionLevel to check for supported languages. As the underlying engine has changed from VNRecognizeTextRequestRevision1, results can differ but are generally more accurate.

  - VNImageOptionCameraIntrinsics
```
public static java.lang.String VNImageOptionCameraIntrinsics()

    VNImageOptionCameraIntrinsics Specifies the camera intrinsics as an NSData or CFData representing a matrix_float3x3. See kCMSampleBufferAttachmentKey_CameraIntrinsicMatrix for details
    Camera intrinsic matrix is a CFData containing a matrix_float3x3, which is column-major. It has the following contents: fx 0 ox 0 fy oy 0 0 1 fx and fy are the focal length in pixels. For square pixels, they will have the same value. ox and oy are the coordinates of the principal point. The origin is the upper left of the frame. [@note] When using a CMSampleBuffer as an input and that sample buffer has camera intrinsics attached to it, Vision will use the camera intrinsic from there unless overwritten by passing in as an explicit option which will take precedence.

```
    VNImageOptionCIContext Specifies the CIContext to be used in Core Image operations of request handler. If this is not specified, Vision will create its own CIContext. This option is helpful when the passed in CIImage is the result of a CIFilter chain that has been executed on a CIContext or uses outputs of a CIImage on a given CIContext as they don't have to transfer to other contexts.
