Pattern Recognition in 2D Data from Digitised Images and Advanced Acquisition Techniques
For scholars investigating written artefacts, automatic pattern detection and recognition can facilitate their research and provide quantitative measurements. Furthermore, it can provide access to additional information, which is typically beyond the reach of scholars, such as fine differences in details, statistical pattern similarities, and invisible structures for human vision. Such computational methods require only digital images or data from advanced acquisition techniques, like microscopes and multi-spectral imaging. Therefore, they are inherently non-invasive. Within the research field Artefact Profiling, this project will create analysis pipelines of 2D data from various acquisition techniques.
During the last decade, considerable advancements have been made in the field of pattern recognition. Nevertheless, most of the state-of-the-art methods depend on the availability of a large number of training samples. These training samples need to be annotated by the users (e.g. names of scribes, exact location of certain letters, spatial boundaries of certain marks, etc.), which might lead to a decision bias because such annotations can be subject to opinions (e.g. school of thought).
Although learning-based approaches can be useful when the training samples, the required annotations, and the needed computational resources are all available, the applicability of such methods is very limited in the case of scarce and unbalanced data, which is prevalent in the research problems presented by scholars from written-artefact research. Therefore, this project focuses on the development and application of learning-free statistical-based computational methods for pattern recognition, which requires no tedious annotation, no training samples, and no costly computational resources.
The goal of this project is to develop and apply learning-free computational methods in order to perform quantitative analysis of patterns in digitised written artefacts and their writing-supports. The main topics are detecting and recognising visual elements, pattern analysis of writing-support materials, and further development of handwriting analysis tools.
