An image or image buffer used in vision detection, with optional metadata.
Metadata about the image (e.g. image orientation). If metadata is not specified, the default metadata values are used.
Initializes a VisionImage object with the given image.
Image to use in vision detection. The given image should be rotated, so its imageOrientation property is set to UIImageOrientationUp value. The UIImage must have non-NULL CGImage property.
A VisionImage instance with the given image.
Initializes a VisionImage object with the given image buffer. To improve performance, it is recommended to minimize the lifespan and number of instances of this class when initializing with a CMSampleBufferRef.
Image buffer to use in vision detection. The buffer must be based on a pixel buffer (not compressed data), and the pixel format must be one of: - kCVPixelFormatType_32BGRA - kCVPixelFormatType_420YpCbCr8BiPlanarFullRange - kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange In practice: this works with the video output of the phone’s camera, but not other arbitrary sources of CMSampleBufferRefs.
