Abstract of thesis
This thesis proposes contributions in classification and pigment identification and quantization using multimodal data. By leveraging advancements in hyperspectral and multispectral imaging technologies and employing deep learning techniques, the research addresses three core questions: the automation of pigment identification from multimodal images mimicking expert-driven process of pigment identification. The applicability of hyperspectral unmixing methods to pigment identification, and the enhancement of classification accuracy through the joint exploitation of spectral and spatial information. The findings, validated through extensive experiments with real paintings and mockup samples, not only contribute significantly to the field of cultural heritage conservation but also open new avenues for future research in pigment identification and conservation practices.
