This paper explores the notion of autarchy of diagrammatic notations for logic debated in the Germanspeaking world of the 18-century, especially as applied to linear diagrams invented by G. W. Leibniz and J. H. Lambert. Keywords— linear diagrams; autarchy; Leibniz; Lambert; Ploucquet

In this paper we present two novel reflectance measurement procedures that requiresampling

Lighting and Lambertian NOTE: NOT FOR DISTRIBUTION!!

The reflected radiation by observed surface is highly dependent on both sun illumination and satellite observation angles. These two angles are also described, respectively, as incident and reflected angles. The geometry-dependence of surface reflectance is usually corrected by a tailored Bi-directional Reflectance Distribution Function (BRDF). It is the most common tool used to eliminate or to...

The complete set of measurements that could ever be used by a passive 3D vision algorithm is the plenoptic function or light-field. We give a concise characterization of when the light-field of a Lambertian scene uniquely determines its shape and, conversely, when the shape is inherently ambiguous. In particular, we show that stereo computed from the light-field is ambiguous if and only if the ...

Introduction: We report Modified gaussian model (MGM) deconvolution analyses [2] of reflectance spectrum of the Yamato (Y) 981031. Petrological characteristics of Y981031 had already reported [1]. Absorption features derived from the MGM deconvo-lution are compared with the petrological characteristics of Y981031, and implication of the absorption features are discussed. Finally, we propose sou...

A popular research topic in computer graphics is the acquisition of the appearance of real-world objects. An important aspect of the appearance of an object is how it reacts to incident illumination. The goal of image-based relighting is to visualize real objects under novel incident illumination, and this without explicit knowledge of the object’s geometry or its material properties. The appea...

The appearance of a soil results from the interaction of its different constituents with incident light. Color and various other attributes of the appearance of soil are highly sensitive to the nature, proportion, particle size and morphology, and spatial association of its mineral and organic components. In fact, color has been used for more than 75 yr to obtain information about these soil pr...
