CITextFeature

Information about a text that was detected in a still or video image.

Declaration

class CITextFeature

Overview

A detected text feature is not necessarily rectangular in the plane of the image; rather, the feature identifies a shape that may be rectangular in space (for example a text on a sign) but which appears as a four-sided polygon in the image. The properties of a CITextFeature object identify its four corners in image coordinates.

To detect text in an image or video, choose the CIDetectorTypeText type when initializing a CIDetector object, and use the CIDetectorImageOrientation option to specify the desired orientation for finding upright text.
