The method includes identifying a set of measurable blocks from one or more blocks in said image. The method further includes dilating each measurable block, in said set of measurable blocks, with a predetermined regular structure to create a set of modified measurable blocks. The method further includes selecting 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. Thereafter, the method includes determining a slope of each measurable block in said second set of measurable blocks. Further, the slope is utilizable to estimate said skew angle of said image. The method is performed by one or more microprocessors."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and systems for estimating skew angle of an image","description":"The disclosed embodiments illustrate methods and systems for estimating a skew angle of an image.
