Claim Text:
1. A method of identifying lines in an image, the method comprising: processing a tile of said image, said processing including: performing a line identification operation on a tile of said image, said line identification operation identifying a line in said tile when a line is present; determining, when said line identification operation identifies a line in said tile of interest: i) a first quantized parameter value used in defining the identified line, and ii) a line weight corresponding to the identified line; updating, based on the determined line weight, i) an accumulated line weight value corresponding to the determined first quantized parameter value defining the identified line ii) a first accumulated parameter weighted sum corresponding to the identified line and iii) a second accumulated parameter weighted sum corresponding to the identified line; and identifying a number of lines in said image based on accumulated values generated from processing multiple different tiles of said image, said identifying a number of lines including identifying n largest accumulated line weights, each of the n largest accumulated line weights corresponding to a different pair of quantized perimeter locations, where n is a positive integer value.
