Original Abstract

In this short paper a possibility of using Hyperspectral Imaging based analysis of water soluble inks is investigated. The current research has investigated this method mostly for marker inks, ballpoint pen inks and gel inks, yet curiously the whole water soluble ink class seems underrepresented. Samples were prepared and hyperspectral images of said samples taken, and some preliminary statistical analysis was performed. The data at this stage suggests that at least some samples are visually distinguishable from other samples, while certain other samples are virtually indistinguishable. A method for applying this knowledge in a handwritten text ink identification is briefly outlined and implemented in a simplified way, the results are promising on good input data, but poor on subpar images. The weaknesses of the method are discussed and potential improvement strategies proposed.
