Claim:
1. A method for estimating a skew angle of an image, said method comprising: identifying, by one or more microprocessors, a set of measurable blocks from one or more blocks in said image, wherein each of said one or more blocks in said image corresponds to a set of pixels of predetermined size, wherein each of said set of measurable blocks corresponds to a block that is identified based on a set of predetermined conditions; dilating, by said one or more microprocessors, each measurable block, in said set of measurable blocks, with a predetermined rectangular structure to create a set of modified measurable blocks; selecting, by said one or more microprocessors, a second set of measurable blocks from said set of modified measurable blocks based on a size of each modified measurable block in said set of modified measurable blocks; and determining, by said one or more microprocessors, a slope of each measurable block in said second set of measurable blocks, wherein said slope is utilizable to estimate said skew angle of said image.
