Analysis of Text Identification Techniques Using Scene Text and Optical Character Recognition

Abstract

In today's era, data in digitalized form is needed for faster processing and performing of all tasks. The best way to digitalize the documents is by extracting the text from them. This work of text extraction can be performed by various text identification tasks such as scene text recognition, optical character recognition, handwriting recognition, and much more. This paper presents, reviews, and analyses recent research expansion in the area of optical character recognition and scene text recognition based on various existing models such as convolutional neural network, long short-term memory, cognitive reading for image processing, maximally stable extreme regions, stroke width transformation, and achieved remarkable results up to 90.34% of F-score with benchmark datasets such as ICDAR 2013, ICDAR 2019, IIIT5k. The researchers have done outstanding work in the text recognition field. Yet, improvement in text detection in low-quality image performance is required, as text identification should not be limited to the input quality of the image.

Data Recognition for Multi-Source Heterogeneous Experimental Detection in Cloud Edge Collaboratives

“…CRNN is a popular deep learning framework in text recognition. This model does not recognize a single text but instead treats the entire line of text as a text unit, directly recognizing the text sequence within that unit (Gupta et al, 2021). This method does not require character segmentation and can utilize the contextual information contained in the text, avoiding irreversible errors that are common to the traditional methods.…”

Machine Learning Methods for Handwriting Recognition

“…MNIST consists of 28x28 pixel grayscale images of handwritten digits, providing a simple yet effective benchmark for character recognition tasks [44,45]. While not as complex as datasets specifically designed for handwriting recognition, MNIST has served as a starting point for researchers entering the field and exploring basic principles of image-based recognition [46].…”

IHEP Docs: A Metadata-Based Unstructured Document Management System

“…The document management platform provides front-end services such as organization structure, document management, authentication & authority unified with IHEP SSO (single sign-on) integrated, etc. By the open standardized APIs of IHEP Docs, the application platform can provide an integrated application services such as WPS collaborative office [9] , CAD online, OCR [10,11] , collaborative sheet, customizable document workflows, and intelligent search engine, and anti-virus etc. It is expected to realize the centralized storage and unified management of the data of information systems and personal terminal devices and eliminate the data islands.…”
