Abstract

After pre-processing the images in character recognition systems, the images are segmented based on certain characteristics known as “features”. The feature space identified for character recognition is however ranging across a huge dimensionality. To solve this problem of dimensionality, the feature selection and feature extraction methods are used. Hereby in this paper, we are going to discuss, the different techniques for feature extraction and feature selection and how these techniques are used to reduce the dimensionality of feature space to improve the performance of text categorization.

Keywords

Character Recognition, Feature Extraction, Feature Selection, Image Segmentation, Pre-processing.
