    abstract     = "In this work, an integrated imaging system to obtain
accurate and reproducible multi-spectral dermatological images
is proposed. The system is made up of an integrating sphere,
light emitting diodes and a generic monochromatic camera. The
system can collect up to 10 different spectral bands. These
spectral bands vary from ultraviolet to near infrared. The welldefined
and diffuse illumination of the optically closed scene
aims to avoid shadows and specular reflections. Furthermore,
the system has been developed to guarantee the reproducibility
of the collected images. This allows for comparative studies of
time series of images.
Two experiments are conducted to show the ability of the
system to acquire highly precise and standardized multi-spectral
images. The first experiment aims to show the capacity of the
system to collect reproducible images. The second experiment
demonstrates that the multi-spectral images provide more information
than the classical thri-chromatic images and that this
information is enough to segment lesions easily. These two facts
together indicate the suitability of the system to collect images
and to summarize and track the evolution of dermatological
diseases."
