About

What is text_renderer?

text_renderer is an open-source tool designed to generate synthetic text line images, primarily for training deep learning Optical Character Recognition (OCR) models like CRNN. It features a modular design, allowing users to easily add different components such as Corpus, Effect, and Layout. A key capability is its integration with Albumentations, providing a wide range of image augmentation effects to enhance dataset diversity. The tool supports rendering multiple corpora on a single image with varying effects, generating vertical text, and creating LMDB datasets compatible with PaddleOCR. It also includes a web-based font viewer and corpus sampler for character balance.

Best used for

Ideal for developers who need to generate synthetic text line images, augment training data for OCR models, and create diverse datasets. Especially valuable for researchers and engineers working on deep learning OCR projects requiring custom or expanded training data.

FAQs

What kind of OCR models can text_renderer help train?

text_renderer is designed to generate text line images suitable for training deep learning OCR models, such as CRNN. The synthetic data helps improve the robustness and accuracy of these models in recognizing text from various sources and styles.

Can I use my own fonts and background images with text_renderer?

Yes, text_renderer allows you to use your own .ttf, .otf, or .ttc font files and background images of any size. This flexibility enables you to create highly customized datasets that match your specific business scenarios or research needs.

How does text_renderer handle character sets for OCR training?

The tool supports filtering characters using a charset file, which is recommended for real-world OCR scenarios where models often support a limited character set. This ensures that generated data aligns with the specific character recognition capabilities of your target OCR model.
