THE FIGURE SOURCE EQUATION AND ITS PHYSICAL CONSIDERATION

Theoretical studies on Iijima's ''Theory of Pattern Recognition,'' whi ch is known as a method of multiple similarity, have shown clearly tha t there are situations when it is difficult to determine the viewpoint and visual field, important parameters to introduce topological aspec ts into the pattern space, observing a figure itself. To cope with thi s problem, this paper proposes transforming the observed image from a figure f(r) to a second-order differential image rho(r), called ''figu re source.'' The aim is to reconstruct the theory in such a way as to enable the application of similarity evaluation methods as in the conv entional case, without compromising the current theory, and all the ne cessary proofs are given. In this paper, the figure source equation as well as rules representing its properties are developed, and several related physical quantities are redefined.
