Convert pictures to text in Java! (OCR implementation)

Today I will share with you a method to implement OCR (picture to text) in Java. The specific implementation is to integrate tess4j into a SpringBoot project. Here are the detailed steps What is Tess4j Before implementing OCR, you must first distinguish the difference between Tesseract and Tess4j. Tesseract is an open source optical character […]

Java can also do OCR! SpringBoot integrates Tess4J to realize image text recognition

What is the Tess4j library First, let me briefly explain xdm to those who have never heard of it. Here we need to clearly distinguish the difference between Tesseract and Tess4j. Tesseract is an open source optical character recognition (OCR) engine that converts text in images into computer-readable text. Supports multiple languages and written languages, […]

Python ocr automatically labels data sets, Python ocr requires no installation

This article mainly introduces Python ocr automatic labeling data set, which has certain reference value. Friends in need can refer to it. I hope you will gain a lot after reading this article. Let the editor take you to understand it together. Translating pictures into text is generally called Optical Character Recognition (OCR). There are […]

gunicorn+flask+PaddleOCR

Foreword Since the company is 2G, some paid public network APIs cannot be used (and are not safe), so we have tried a variety of open source OCR frameworks internally. The first is gossiperact, an OCR module encapsulated in golang. The accuracy of multi-digit and letter recognition using the English model is slightly higher, but […]

Decoration mode (Democrator) – single responsibility class, structural mode

In some cases, we may “excessively use inheritance to extend the functionality of objects”. Due to the static characteristics introduced by inheritance for types, this extension method lacks flexibility; and with the increase of subclasses (the increase of extension functions) ), the combination of various subclasses (combination of extended functions) will lead to the expansion […]
