OCR Studio Debuts New AI Technology That Requires 32% Less Compute for ID Recognition at ICMV 2025 in Paris

OCR Studio, a developer of ID scanning solutions, unveiled IIRDoc-Net – an advanced ultra-lightweight neural network architecture that is able to recognize IDs with 32% fewer operations than existing state-of-the-art models. The new AI technology is available on mobile phones, tablets, and desktops, and is already used by the company's clients from banking, retail, and healthcare. The invention was presented at the 18th International Conference on Machine Vision (ICMV 2025) in Paris.

Automated identity document recognition is widely used in areas such as banking, logistics, and border control. Today’s shift toward mobile platforms demands these technologies to be performed even on low-budget devices with limited computational resources. At the same time recognition models must have an extended receptive field to keep the calculations high-accurate and to deal with document images’ projective distortions, noise, motion blur, and poor lighting. However, most of the models with wide receptive fields are too heavy to deliver a real-time document analysis on a mobile device which is crucial for modern online services.

OCR Studio’s solution addresses this problem by integrating a block of learnable Infinite Impulse Response (IIR) filters. These filters allow the receptive field to be adjusted by incorporating both current inputs and prior outputs, which is typically not implied even by the state-of-the-art methods. Evaluation on MIDV-500 and MIDV-2019 datasets demonstrated a 32% reduction in computation needed for ID recognition compared to best competing approaches. Actual technology has been implemented in the latest version of OCR ID-scan that is effectively used by government, fintech, HR, and other services for document-processing automation.

A paper about the IIRDoc-Net technology, unveiled by the OCR Studio team, will be published in the electronic proceedings of the International Society for Optics and Photonics (SPIE), marking the team’s debut at a major international scientific conference of such level.
