Discovering Perceptually Near Granules
James Francis Peters · IGI Global eBooks · 2010
The problem considered in this chapter is how to discover perceptual granules that are in some sense near each other. One approach to the solution to the problem of discovering perceptual granules close to each other comes from near set theory. This is made clear in this chapter by considering various nearness relations that define coverings of sets of perceptual objects that are near each other. A perceptual granule is something that is graspable by the senses or by the mind. Every perceptual granule is represented by a set of perceptual objects that have their origin in the physical world. This means that a perceptual granule does not include the empty set. Hence, each family of perceptual granules is a dual chopped lattice. Both perceptual near sets and tolerance near sets are presented in this chapter. Both the theory and applications of perceptually near granules are presented in this chapter.
