Japanese OCR Images Data – Images with Transcription

Home » Case Study » Japanese OCR Images Data – Images with Transcription

Project Overview:

Objective

We have successfully assembled a comprehensive dataset of Japanese OCR Images Data, including OCR images and their precise transcriptions in Japanese. This dataset is designed to enhance the training and evaluation of OCR and text recognition models.

Scope

Our project entailed the meticulous collection and transcription of a diverse array of images containing Japanese text, crafting a dataset that guarantees quality for OCR model development.

Sources

We sourced a wide-ranging collection of image types, including scanned documents and handwritten notes, and utilized crowdsourcing to augment our dataset with authentic handwritten text samples.

Data Collection Metrics

Total OCR Images Collected: 50,000 images
Handwritten Samples Collected: 10,000 samples
Total Data Annotated: 60,000 data points

Annotation Process

Stages

Our team curated and annotated a varied set of images, employed OCR technology for initial text extraction, and engaged Japanese-speaking experts for meticulous transcription validation.

Annotation Metrics

OCR Images with Transcriptions: 50,000 pairs
Handwritten Samples: 10,000 samples
Transcription Validation Cases: 5,000 (randomly selected for validation)

Quality Assurance

Stages

We conducted rigorous transcription verification and adhered to stringent privacy and data security protocols to ensure the integrity and security of the dataset.

QA Metrics

Transcription Validation Accuracy: Ensure a high level of accuracy (e.g., 99%+) in transcription validation.
Privacy Audits: Ongoing to ensure compliance

Conclusion

The dataset we have collated is an invaluable asset for the advancement of OCR and text recognition technology in the Japanese language, characterized by its diversity and precision.
