Various Traditional and Nature Inspired Approaches Used in Image Preprocessing
Many systems have been designed to fulfill the requirements of the society. OCR is providing a platform to illiterate or visually impaired persons by converting handwritten/Printed document in digitized format automatically. Many researchers worked on the Marathi OCR, but still require lot of improvement as per the user's requirement. Many algorithms have been developed for image processing. Nature inspired computing uses the base of the nature to get the optimized result for the problems e.g. humans, insects, nature, animal behavior. The main purpose of this paper is to provide the knowledge of the techniques including the traditional and nature inspired optimization algorithm proposed by the researchers in area of image processing. We aim to provide advantages and disadvantages of the traditional and nature inspired methods, which would help researchers to select the specific method for the applications.
