![]() Tesseract is widely used in the fields of image recognition and digitalizing documents.ĮasyOCR is an open-source and ready-to-use OCR with almost 80+ language supports. The development time cost is relatively low-you can simply tweak the demo code. It has a complex authentication process, but the overall experience is not bad. Tesseract delivers impressive OCR accuracy, particularly for machine-printed text and well-scanned documents, making it suitable for various applications. And, it have some problem at recognizing handwriting and low-quality scans. It delivers high OCR accuracy for machine-printed text, but for other type of files, you need to manual training and tuning for specific use cases. In our test, we find that the accuracy of Tesseract output depends on various factors, like language, image quality, data size, pre-trained data, etc. It have many documentation on the official website, you can start with the Beginner’s Guide an choose the guide from 4 categories which has dedicated documentation link for users with different needs. At the time of writing, Tesseract’s main repository has 43.8k+ stars and 7.8k+ forks.

Tesseract was developed in C++ and has wrappers available for Python, Java, Swift, Ruby, etc. 1 version, Tesseract now covers up to 116 languages. It is Known for its accuracy and provides customization and functionality for further development. Tesseract is one of the most well known OCR open-source engines which initially developed by Hewlett-Packard and now maintained by Google since 2006. OCR result are highly related with input image quality, in our test we input images in different resolution to the program (100DPI/150DPI/300DPI/600DPI) and the performance are as follows. The OCR recognition performance of Cisdem OCRWizard is as follows ![]() Handwriting Recognition: OCR handwriting images and extract text as DOCX, TXT, or RTF. ![]() Screenshot Recognition: Capture screen and recognize text in captured screenshots.Īdvanced recognition: Convert selected areas and see page region and document properties. Partial Image Recognition: Choose to only recognize text from selected areas. PDF Recognition: Convert scanned or normal PDF files and save it in DOCX, TXT, or RTF. Image Excel Recognition: Extract table data from images and save in Excel format. Single Image Recognition: Recognize text from single images and save as DOCX, TXT, or RTF.īatch Images Recognition: Recognize text from batches of images and process all at one time. This program also have other 7 modes, which you can test one by one, and it has an Advanced recognition mode which give high accurate result and you can choose which area to recognize and which area to ignore, which comes very handy. Launch it, then choose a mode according to your specific needs.Īs we are testing the overall performence and accuracy of this app, here we choose the "Batch Image Recognition" mode, in this mode we can add as many images as we like and the program will process all added files in batches.Ĭlick "Start" the program will batch convert and etract text from images. Choose from 8 OCR Modeĭownload and install Cisdem OCRWizard. Steps to extract text from images and PDF with Cisdem OCRWizard: 1. Although it’s not an open source OCR tool, it can surely meet requirements. It offers a freetrial so you may download and try how it performs. Users can choose to output extracted text in DOC, RTFD or Text format. ![]() It offers OCR recognition in 8 different modes and It supports various image or PDF formats. OCR performance, language support, usage cost, customization options, and community support.Įasy-to-Use Pre-trained OCR Software (Special Recommend)Ĭompared with open source OCR tools, Pre-trained models offer convenience and ease of use, and is a very good option for people who have no code skill and have limit resources and expertise to develop and maintain open source OCR tools.Ĭisdem OCRWizard is a fantastic OCR software that is widely used by all levels of users, and it is compatible with both Windows and macOS computers.
