The Biometrics for Arts (ArtMetrics) workshop aims to explore the intersection of biometrics, computer vision and the arts to provide a more nuanced understanding of an artwork's provenance and maker(s). In the same way as Biometrics serves as a tool for person identification from unique phenotypic or behavioural traits, Biometrics for Arts aims at artist recognition from unique attributes detected on works of art, thus fostering dialogue between engineers, computer scientists, heritage scientists, conservators, and art historians. This workshop will showcase innovative applications of computer vision in the visual art domain, emphasizing the role of technology in supporting conservation practices and enhancing the management of museum and private collections. Key topics include pattern recognition in works of art, AI-driven artistic generation, AI-driven analysis of multimodal imaging data of works of art, and digital restoration of different media. ArtMetrics seeks to inspire interdisciplinary collaboration, highlighting how computer vision can both interpret and enhance the diverse world of art.
