Information technology for cultural heritage
Information technology applications in the field of cultural heritage include various disciplines of computer science. The work flow from archaeological discovery to scientific preparation demands multidisciplinary cooperation and interaction at various levels. This article describes the information technology pipeline from the computer science point of view. The description starts with the model acquisition. Computer vision algorithms are able to generate a raw three-dimensional (3-D) model using input data such as photos and scans. In the next step, computer graphics methods create an accurate, highlevel model description. Besides geometric information, each model needs semantic metadata to perform digital library tasks such as storage, markup, indexing, and retrieval. A structured repository of virtual artifacts completes the pipeline - at least from the computer science point of view.
