var minimumConfidence: VNConfidence { get set }
Vision won't return rectangles with a confidence score lower than the specified minimum.
The confidence score ranges from 0 to 1, inclusive, where 0 represents no confidence, and 1 represents full confidence.
var minimumA float specifying the minimum aspect ratio of the rectangle to detect, defined as the shorter dimension over the longer dimension.
var maximumA float specifying the maximum aspect ratio of the rectangle to detect, defined as the shorter dimension over the longer dimension.
var quadratureA float specifying the number of degrees a rectangle corner angle can deviate from 90°.
var minimumA float specifying the minimum size of the rectangle to be detected, as a proportion of the smallest dimension.
var maximumAn integer specifying the maximum number of rectangles Vision returns.
