Computer Vision and Computational Image Science may be defined as the study of images and the application of scientific methods to their measurement, generation, analysis and representation. It includes all types of image processing, including optical image production, sensing, digitisation, encoding, processing. To deeply understand vision and imaging systems, a mathematical and physical modelling is needed. This understanding is required for design and evaluation of different vision systems, both biological and artificial, in a unified way.
The design of efficient imaging systems has so far been guided by the criterion that “what the user cannot see does not matter”. In modern applications, this is not sufficient enough. Since e.g. it should be possible to reconstruct on display the image of a painting from a digital archive under different illuminations. From the human vision point, the problem is that visual perception is one of the most elusive and changeable of all aspects of human cognition, and depends on a multitude of factors. Successful research and development of color imaging products must therefore combine a broad understanding of psychophysical methods with a significant technical ability in mathematics and computer science. The variety of image sources and reproduction media, in combination with miscellaneous illumination and viewing conditions creates challenges to manage a predictable and consistent reproduction of color. Solving this problem not only involves understanding image appearance and its relation with regard to image quality measurements and Human Vision models.
Appreciating the principles of Human Vision models such as color image appearance models also opens the door for enhancing two other technologies in consumer imaging. A first one is image enhancement, for example by means of multiscale color image processing. A second one deals with automatic creation of tags or indices based on color aware content to classify or retrieve images in a database or on the network. A particularly important problem in digital imaging (e.g. in soft proof or in medical applications) is the consistency and predictability of the objects displayed with regard to the objects viewed. Excellent results have been achieved already under controlled illumination conditions, but it is expected that approaching this problem using multi-spectral techniques will result in a color reproduction that is more stable under different illumination conditions.
