CIDetectorMBS.CIDetectorImageOrientation as string

Type	Topic	Plugin	Version	macOS	Windows	Linux	Console & Web	iOS
shared method	CoreImage	MBS MacCG Plugin	14.1	Yes	No	No	Yes, macOS only	No

Function: An option for the display orientation of the image whose features you want to detect.
Notes:
The value of this key is an NSNumber object whose value is an integer between 1 and 8. The TIFF and EXIF specifications define these values to indicate where the pixel coordinate origin (0,0) of the image should appear when it is displayed. The default value is 1, indicating that the origin is in the top left corner of the image. For further details, see kCGImagePropertyOrientation.
Core Image only detects faces whose orientation matches that of the image. You should provide a value for this key if you want to detect faces in a different orientation.
Available in OS X v10.8 and later.

shared method	CoreImage	MBS MacCG Plugin	15.4	Yes	No	No	Yes, macOS only	No

Function: One of the configuration keys.
Notes:
The number of perspectives to use for detecting a face in video input.

The value for this key is a number 1, 3, 5, 7, 9, or 11. At higher numbers of angles, face detection in video becomes more accurate, but at a higher computational cost.

Available in OS X 10.11 and later.

CIDetectorMBS.detectorOfType(type as string, context as CIContextMBS = nil, options as dictionary = nil) as CIDetectorMBS

Type	Topic	Plugin	Version	macOS	Windows	Linux	Console & Web	iOS
shared method	CoreImage	MBS MacCG Plugin	16.0	Yes	No	No	Yes, macOS only	No

Function: Returns a new detector instance of the given type.
Notes:
The type is used to specify the usage intent.
The context argument specifies the CIContext to be used to operate on the image. May be nil.

If the input image to featuresInImage is the output of a CoreImage operation, it may improve performance to specify the same context that was used to operate on that image.

The detector may do image processing in this context and if the image is on the GPU and the specified context is a GPU context this may avoid additional upload to / download from the GPU. If the input image is on the CPU (or the output from a CPU based context) specifying a GPU based context (or vice versa) may reduce performance.

The options parameter lets you optinally specify a accuracy / performance tradeoff. Can be nil or an empty dictionary.
