Skew angle estimation is an important component of optical character recognition (OCR) systems. In this paper, a new optimizing method is introduced that is called "Finding the Skew with Radon (FSR)" in order to estimate the skew of the handwritten text. The above mentioned method has three stages. First of all, input text image is converted into a binary form and then the words and sub-words are became dilated. Then, the pattern angle is attained by using Radon transform. Finally, the inversion or non-inversion of the result image from the previous stage is recognized by extraction of horizontal histogram of that image and statistical analysis. To demonstrate the FSR method's outcomes, this proposed method is simulated for a complex of various Persian handwritten images, and then it is observed that its results in comparison with last methods are significantly optimized.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
