Paper Abstract

Usually, pictures are represented as the set of pairs composed of the location (x, y) of a point and its intensity level f(x, y). For analysis of the scalar function f(x, y), the theory of structure lines are effective because the lines have invariant features for variation of environments where a real object gives a corresponding picture. The division line is especially important in structure lines because the line divides convex or concave domains. Then, we propose the concept of subject mode region in order to analyze the structure of a picture. Subjective mode region is defined as the region enclosed by some division lines. Therefore, subjective mode regions are specified by neighborhood mode relation of luminance value or chrominance separation. The concept of subjective mode region is useful for a stereoscopic picture for a complicated picture such as a human face. A stereoscopic picture is generated by applying the simple geometrical models to subjective mode regions.
