Abstract :Nowadays, optical character recognition technology is not so advanced as to compete with human perception ability. Parameters such as scene complexity, irregular lighting conditions, skewness, blur and distortion, aspect ratios, perspective impairment, fonts, multilingual environments negatively affect the success of the optical character recognition technology. The aim of this article is to create an algorithm that can resolve irregular words whose characters` scales and rotations are modified. In the algorithm, fractal dimension tool, a fast and stable recognition method, is used. From this viewpoint it is desired to make optical character recognition technology closer to human perception. In order to analyze the algorithm, fractal dimension and image compression data of big, and small alphabetic characters in the tahoma font were recorded in the database. Then, using these characters, irregular word images were obtained. These images, were analyzed by the algorithm built in matlab program and the results were obtained.
Keywords : Fractal Dimension, Pattern Recognition, Optical Character
