Visual Pattern Recognition by Assignment of Invariant Features and Feature-relations
DAVID H. FOSTER · Optica Acta International Journal of Optics · 1977
The capacity of the visual system to recognize patterns that have undergone various transformations may be explained by a scheme in which the system associates with each pattern certain features and feature-relations that remain constant under the action of the given transformations. Some of the characteristics of such a recognition scheme are examined and an approach is proposed for the analysis of the pattern structure determined by these feature and feature-relation assignments. Data are presented relating to the stability of these assignments under changes in recognition criteria.
