An image analysis request that finds projected rectangular regions in an image.
- iOS 11.0+
- macOS 10.13+
- tvOS 11.0+
Use this type of request to find the bounding boxes of rectangles in an image. Vision returns observations for rectangles found in all orientations and sizes, along with a confidence level to indicate how likely it is that the observation contains an actual rectangle.
To further configure or restrict the types of rectangles found, set properties on the request specifying a range of aspect ratios, sizes, and quadrature tolerance.
