RESEARCH & DEVELOPMENT
Document recognition technologies
When recognizing documents in a video stream and in photos we must deal with uncontrolled capturing conditions and unknown hardware parameters. In order to scan documents directly on a mobile device, the key aspect of the algorithms is their computational complexity and the footprint of the configuration modules, including the sizes of neural network models. The relevance of the entered data generally depends on the input data and thus on the user, which means the recognition systems and algorithms must be highly failure-resistant. Smart Engines applies deep scientific thinking to create OCR technologies that overcome common challenges to document recognition in video streams, scans, and photos.
Computational Imaging and Tomography
As one of the most powerful non-destructive testing methods in the optical range, machine vision remains limited to the surface of an object. Smart Engines specialises in the scientific development and practical deployment of computed tomography software that allows the exploration of three- dimensional internal structures – essential for medicine, industrial diagnostics, and scientific laboratories.
- Calibration and alignment of new generation tomographs.
- Optimised and customised reconstruction of images from data collected in difficult conditions such as ultra-low doses, tomosynthesis, the presence of highly absorbing inclusions in the object, etc.
- Computational visualisation with automatic processing and semantic analysis of results.

DATASETS OF ID DOCUMENTS: MIDV-500 and MIDV-2019
Insufficient public datasets prevent the comprehensive study of AI-powered document recognition on mobile devices. Existing datasets can be useful for certain tasks, but they are not enough to create and test the technologies required for recognizing identity documents. Until now. The Smart Engines Mobile Identity Document Video dataset (MIDV-500) consists of 500 video clips covering 50 different identity document types. Since this kind of document contains personal data, all source material is either publicly available or copyright-free.
An extension of MIDV-500, the MIDV-2019 dataset contains additional video clips, shot with modern high-resolution mobile cameras, to address issues of projective distortions and variable lighting conditions.
