Abstract Photograph conservators assembled a collection of 149 photographs by F. Holland Day. Digitized one-squared centimeter samples of textures of the corresponding papers were made available to image processing teams, with the aim of assessing the potential interest and efficiency of automated unsupervised clustering. A procedure combining anisotropic multiscale representations and spectral clustering, already used in art photographic paper clustering challenges, was complemented with the design of a clustering robustness index. Comparisons of the achieved automated clustering against an a priori and independent grouping performed by visual inspection of the textures by photograph conservators triggered fruitful interdisciplinary interactions and discussions.
