An appendix to “Texture databases – A comprehensive survey”

• Finding suitable texture databases for experimenting is challenging and time-consuming.
• We complement the work “Texture databases – A comprehensive survey”.
• We categorise, survey and discuss the main features of 20 additional texture databases.
• The work is a useful guide for researchers and practitioners.

Texture analysis is an area of intense research activity. Like in other fields, the availability of public data for benchmarking is vital to the development of the discipline. In “Texture databases – A comprehensive survey”, Hossain and Serikawa recently provided a precious review of a good number of texture datasets, and put an order into this scattered field. The aim of this appendix is to complement the cited work by providing reference to additional image databases of bio-medical textures, textures of materials and natural textures that have been recently employed in experiments with texture analysis. There is in fact a good number of little-known texture databases which have very interesting features, and for this reason are likely to receive increasing attention in the near future. We are convinced that this extension, along with the original article, will be useful to many researchers and practitioners working in the field of texture analysis.
