28. A method of tracking text in image data, the method comprising:
-
receiving image data from an image capture device, the image data including text; processing at least a portion of the image data to locate corner features of the text; and in response to a count of the located corner features not satisfying a threshold, processing a first region of the image data that includes a first corner feature to locate additional salient features of the text. - View Dependent Claims (29, 30, 31)

32. A method of tracking text in multiple frames of image data, the method comprising:
-
receiving image data from an image capture device, the image data including text; identifying a set of features of the text in a first frame of the image data, the set of features including a first feature set and a second feature; identifying a mapping that corresponds to a displacement of the first feature set in a current frame of the image data as compared to the first feature set in the first frame; and in response to determining the mapping does not correspond to a displacement of the second feature in the current frame as compared to the second feature in the first frame, processing a region around a predicted location of the second feature in the current frame according to the mapping to determine whether the second feature is located within the region. - View Dependent Claims (33, 34, 35)

36. A method of estimating a pose of an image capture device, the method comprising:
-
receiving image data from the image capture device, the image data including text; identifying a distorted bounding region enclosing at least a portion the text, the distorted bounding region at least partially corresponding to a perspective distortion of a regular bounding region enclosing the portion of the text; determining a pose of the image capture device based on the distorted bounding region and a focal length of the image capture device; and generating augmented image data including at least one augmented reality feature to be displayed at a display device, the at least one augmented reality feature positioned within the augmented image data according to the pose of the image capture device. - View Dependent Claims (37, 38)
