Internship - Low quality barcode decoding

Description courte

At IDEMIA Public Security, we support governments and public institutions with advanced identity and security solutions.

Our teams develop technologies that help build a safer world by protecting people, assets, and identities.

IDEMIA develops high-performance algorithms to authenticate Identity documents. One of them is the barcoding decoding algorithm. Barcodes are useful to check the consistency between the text written on the document and the one encoded in the barcode. In case of low-quality barcode, the percentage of failures is more important. Low-quality means blurred image, low resolution image or badly printed barcodes. The purpose of the internship is to design, implement and evaluate deep learning algorithms to improve the percentage of decoded barcodes. It can be restoration algorithms, binarization algorithms, super-resolution algorithms, … or the combination of these algorithms.

Key Missions

• Design, implement and evaluate deep learning algorithms to improve the percentage of decoded barcodes
• Develop deep learning models to enhance degraded barcode images
• Build and preprocess datasets with real and synthetic degradations
• Train and evaluate models in PyTorch using advanced vision architectures
