How to Custom Font Training for Tesseract 5 in C#

In this tutorial, we walk through the process of training Tesseract 5 OCR with custom fonts. Beginning with downloading IronOCR for Windows, we establish a Linux environment using WSL and Ubuntu for effective test training. The tutorial details commands to install required packages and libraries, ensuring a smooth setup. Custom fonts are integrated by copying files to designated directories and updating configuration files. Using GitHub repositories, we download and prepare necessary tutorial files, adjusting paths and settings to accommodate custom fonts. The guide explains generating box and TIFF image files, crucial for training, and modifies file extensions for compatibility. By replacing default training data with enhanced files from GitHub, we create a custom font.training data file. The training process, set for 100 iterations, is highlighted, with recommendations for increasing iterations and training sets for improved accuracy. This comprehensive tutorial ensures users can effectively train OCR systems to recognize custom fonts, enhancing the utility of OCR libraries.
