Image quality control for cultural heritage digitization projects
Why the quality control is so important?
Digitizing a collection is a Herculean task in terms of labour, costs, and mindshare. It requires a coordinated work of different departments and professionals, and the allocation of a huge amount of institutional resources. Therefore it is essential to be sure about its quality and efficiency.
To achieve good and useful digitization it is not enough to take some nice-looking, high-resolution photos, but the digitization process has to result a standardized, quality-controlled container, including qualified images and metadata: a Preservation Digital Object. A PDO faithfully records the current state of the real-world object, and in the same time, it can be a digital surrogate, and even, for some purposes, the substitution of the original artefacts.
