Abstract

Abstract: In library heritage, the practice of reusing fragments of older manuscripts was very common, providing complex structures characterised by several overlapped features. Pulsed Thermography enables non-destructive investigations of such a stratigraphic structure and the detection of hidden texts. In this work, a study of the contrast generation in their thermographic detection is presented, aimed to the evaluation of the edges distortion for enhancing the readability of such features which is crucial for palaeographic purposes.
