There has recently been a resurgence in interest in skin characteristics, driven by a number of different technologies and application areas where accurate skin measurement and reproduction are key factors. Application areas include the diagnosis of cutaneous diseases, segmentation for face detection and recognition, reproduction for the graphic arts, and matching for body and maxillofacial soft tissue prostheses. For such applications, a comprehensive knowledge of the range of skin shades that represent individuals, an understanding of how skin characteristics varies, and how people perceive these differences in a wide range of viewing conditions are strongly desired. The goal of this workshop is to bring together practitioners and academics from a range of disciplines to explore the outstanding issues in the measurement, reproduction, and perception of skin, with a particular emphasis on skin imaging.

Color is fundamental across sciences, theology, languages, and technology, and for many centuries, has been inextricably bound to art and design. As symbolic, therapeutic, synaesthetic or surreal, it has the power to give pleasure or discomfort. As a sensation, Josef Albers described the properties and relationship of color in art, that 'deceives continually'.

Color has drawn artists and scientists into fierce debates. Newton's experiments on the phenomena of light and exploration on pigments were not without adversaries. William Blake regarded Newton as lacking in imagination. The poet John Keats decried Newton had 'destroyed the poetry of the rainbow by reducing it to a prism'.

Artists for centuries explored and captured the appearance of materials through pigments and drawing. Sometimes creating the most lifelike images that one could ask, is this is a photo or a painting? Color is reflected and transmitted by its medium - as pigments, textiles, light and film, as structural color that appears in glass and pottery, iridescent surfaces such as feathers and beetles, or inter-reflections between colored objects and surfaces.

This workshop calls upon artists, designers, and historians to discuss the complexities of color in the arts.

Color imaging received a lot of attention during the rise of the smartphone era—especially due to its associated cameras—and this is still the case, as different manufacturers use the quality of the photos obtained to publicize a new phone. The fight between these companies has garnered lots of attention in some specific research areas, such as image quality and image fusion. Currently, it seems we are again at a turning point with the advent of new technologies such as AR/VR, 3D printing, wide color gamut, and HDR, to name just a few. During this round table, world-leading color scientists will debate on these topics, looking specifically at where we have come from in color imaging research and where we are heading.

With the development of various new imaging technologies, virtual reality (VR), augmented reality (AR), and mixed reality (MR) are becoming more and more popular for use in various industries for different purposes. Little research, however, has been carried out to investigate issues related to appearance and perception when using these new technologies. To facilitate the development and to improve the user experience, a comprehensive understanding about how the human visual system responds to stimuli and scenes produced by VR/AR/MR is important. In this workshop, speakers present the latest research and have an open discussion about outstanding issues that need scientific research.
