CNN and Fuzzy Rules Based Text Detection and Recognition from Natural Scenes

Abstract

In today's real world, an important research part in image processing is scene text detection and recognition. Scene text can be in different languages, fonts, sizes, colours, orientations and structures. Moreover, the aspect ratios and layouts of a scene text may differ significantly. All these variations appear assignificant challenges for the detection and recognition algorithms that are considered for the text in natural scenes. In this paper, a new intelligent text detection and recognition method for detectingthe text from natural scenes and forrecognizing the text by applying the newly proposed Conditional Random Field-based fuzzy rules incorporated Convolutional Neural Network (CR-CNN) has been proposed. Moreover, we have recommended a new text detection method for detecting the exact text from the input natural scene images. For enhancing the presentation of the edge detection process, image pre-processing activities such as edge detection and color modeling have beenapplied in this work. In addition, we have generated new fuzzy rules for making effective decisions on the processes of text detection and recognition. The experiments have been directedusing the standard benchmark datasets such as the ICDAR 2003, the ICDAR 2011, the ICDAR 2005 and the SVT and have achieved better detection accuracy intext detection and recognition. By using these three datasets, five different experiments have been conducted for evaluating the proposed model. And also, we have compared the proposed system with the other classifiers such as the SVM, the MLP and the CNN. In these comparisons, the proposed model has achieved better classification accuracywhen compared with the other existing works.

Embedded System Based Raspberry Pi 4 for Text Detection and Recognition

“…In the recent years, deep learning techniques have been utilized to address the problems such as OCR analysis and text detection, extraction and recognition from natural scene images [9][10][11][12][13][14]. However, better performance can be achieved by utilizing deep learning technique [15].…”

The Design of a Music Scene Recognition Method and System Based on Artificial Intelligence

“…Scene recognition is one of the fundamental problems in computer vision research and has a wide range of applications in robotics [5].Veronica Naosekpam introduces a new adaptive scene recognition method that exploits self-supervised translation between modalities. In fact, learning from RGB to depth and vice versa is an unsupervised process that can be trained jointly on data from multiple cameras and helps to bridge the gap between the extracted feature distributions.…”

Automatic Text Recognition Based on Intelligent Machine Learning Technology

“…Some scholars have proposed a method to sort Chinese characters based on the combination of part of speech features and statistical learning rules. Some scholars pointed out when studying the BP neural network and machine vision technology that the new structure can effectively improve the training efficiency and reduce the error rate by manually marking different texts to replace the templates needed at present [7][8]. Therefore, based on text classification technology, this paper studies the automatic recognition of intelligent machine learning characters.…”
