OCR expanded as optical character recognition, is a subset of pattern recognition systems and is an active research area of significant scientific and practical importance. His OCR technique uses an optical scanner to first digitise typed letters. Following the identification and segmentation of each character, the resulting character picture is forwarded to the preprocessor for normalization. The characteristics are then classified based on certain traits that were extracted from them. There are numerous methods for feature extraction, each with a different purpose, and feature extraction is a crucial step. This paper provides an overview of feature extraction methods for character recognition. The selection of the feature extraction method is the most important factor in achieving high recognition performance in a character recognition system. Different feature extraction methods are designed for different character representations. The most effective feature extraction technique should be chosen for a given application after a number of promising methods have been identified and empirically tested. Today, many paper documents are digitized, facilitating information processing such as searching, analysis, and conversion. This article presents his OCR usability analysis for automated data entry. Our research looked at the entire process of digitizing print. Scanning, data indexing, approval, market. The study showed the recognition of printed text is reliable and data processing is significantly faster. On the contrary, handwritten text seemed difficult for his OCR system to recognize
