Color reproducibility of skin lesions in multispectral video: Experimental evaluation

The color reproduction accuracy of a multispectral video system was visually evaluated by expert dermatologists to investigate the feasibility of the system in telemedicine applications. The erythema produced by a skin prick test was used as a substitution of real skin lesion, and the dermatologists performed a color matching experiment, in which the color chips were compared with the reproduced images and the real skins. As a result, the mutisperctral video system, consisting of 6-band HDTV camera, 6-primary display and spectrum-based color reproduction, decreased the perceptual color difference between the reproduced image and the real object, as compared with a conventional 3-band HDTV system. It was also shown that the oversights of skin lesions could be reduced in 6-band video reproduction. Through the experiments including multispectral video transmission between the remote hospitals in addition to above skin color matching, dermatologists rated that the natural color reproduction realized by multispectral video is almost satisfactory for the diagnosis of skin disorders.

More about this publication?
  • CIC is the premier annual technical gathering for scientists, technologists, and engineers working in the areas of color science and systems, and their application to color imaging. Participants represent disciplines ranging from psychophysics, optical physics, image processing, color science to graphic arts, systems engineering, and hardware and software development. While a broad mix of professional interests is the hallmark of these conferences, the focus is color. CICs traditionally offer two days of short courses followed by three days of technical sessions that include three keynotes, an evening lecture, a vibrant interactive (poster) papers session, and workshops. An endearing symbol of the meeting is the Cactus Award, given each year to the author(s) of the best interactive paper; there are also Best Paper and Best Student Paper awards.
