Pixel values of a first pixel block in a binary image are converted into first pixel values. A second pixel block comprising second pixel values is generated, based on pixel shifting in the first pixel block by a pre-determined count. A frequency value for a pixel-of-interest in the first pixel block is determined, based on a count of a pre-specified type of third pixel values. Other plurality of frequency values for other pixels-of-interest in other plurality of first pixel blocks are estimated when a mode value, corresponding to a plurality of frequency values of pixels-of-interest in a plurality of first pixel blocks, exceeds a pre-determined threshold mode value. Based on the determined plurality of frequency values, one or more image processing operations on the binary image are performed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing method and system for classification of halftone frequencies","description":"The disclosed embodiments illustrate an image processing method and system for classification of halftone frequencies.
