Application ID: 14837766

Base Claim:
1. An apparatus for determining a rotation angle of text within an image, the apparatus comprising: circuitry configured to compute, for each object of a plurality of objects included in the text, a distance to a closest neighboring object, compute an average distance of the distances to the closest neighboring objects, determine a ratio between the average distance and an average font stroke width, the average font stroke width being an average of a font stroke width of each of the plurality of objects, and determine the rotation angle of the text by comparing the ratio to a threshold value.

Claim 2:
2. The apparatus of claim 1 , wherein the circuitry is further configured to determine a bounding rectangle for each object, the bounding rectangle surrounding the respective object and contacting outer-most portions of the respective object, and the circuitry computes the distance to the closest neighboring object by calculating the distance of the respective bounding rectangle to a closest neighboring bounding rectangle.
