Abstract In recent years it is noteworthy how the use of Computational Vision
techniques in processing and quality control of products has advanced. The
available resources in both electronic and computing were important factors in the
automation development, allowing constant monitoring during the process. Such
techniques have systematically evolved in the international commerce. However,
there is a lack of standardization on quality control of products using image
analysis. Measurements using digital image should consider important aspects,
such as the effects of lighting, characteristics of the environment, the types of
illuminants, the observers, to name a few, all that beyond the traceability of the
system and the definition of standards. With this in mind, the aim of this chapter is
to discuss the relevance of the main variables that influence the color measurement
of images using computer vision techniques, in order to promote some thought
about the needs of standardization.
