Scale ratio ICP for 3D point clouds with different scales
2013 IEEE International Conference on Image Processing, 2013In this paper we propose a method for matching the scales of 3D point clouds. 3D point sets of the same scene obtained by 3D reconstruction techniques usually differ in scale. To match scales, we estimate the ratio of scales of two given 3D point clouds.

CROWN RATIO INFLUENCES ALLOMETRIC SCALING IN TREES
Ecology, 2006Allometric theories suggest that the size and shape of organisms follow universal rules, with a tendency toward quarter-power scaling. In woody plants, however, structure is influenced by branch death and shedding, which leads to decreasing crown ratios, accumulation of heartwood, and stem and branch tapering.

The Arithmetic Teacher, 1977
My mathematics class was a high ability, sixth-grade group who understood ratio and scale, but, at the start of the project described here, needed practical exercises in using these skills. The need for practice in applying the concepts of ratio and scale suggested the use of architectural floor plans.

Micko's “Halo”-Model for Multidimensional Ratio Scaling
Psychometrika, 1975It is argued that (1) the halo-model of Micko is probably too restrictive to fit empirical data, (2) the model misrepresents unrelated percepts as bipolar structures, (3) all variations will probably be interpreted as qualitative, (4) the model requires all dimensions to be bipolar, (5) interpretations of orthogonality of factors and of factor loadings

A “Halo”-Model for Multidimensional Ratio Scaling
Psychometrika, 1970A model for direct multidimensional ratio scaling is presented, based on the concepts “common” and “difference” of the “halos” of two percepts. Measures of halos and their differences are proportional to lengths of corresponding percept vectors and their distance in subjective space.

THE GARNER‐ATTNEAVE THEORY OF RATIO SCALING
Scandinavian Journal of Psychology, 1967The theory is shown to be logically and psychologically untenable, being based on a first order phenomenological‐numerical (PN) relation which cannot exist. An alternative theory, not possessing this shortcoming because it involves a second order PN relation, explains both ratio and category scaling.

A Proposed Method for Absolute Ratio Scaling
Psychometrika, 1950A method of ratio scaling is described for treating comparative judgments of paired stimuli. A method of comparative judgment developed by Metfessel is employed. Formulas for scale values and the solution of a sample problem are provided. The method is designed to provide internal-consistency checks on the scale values.

Scale Covariance and Scale-ratio Covariance in Turbulent Front Propagation
2009We address the implications of scale symmetries in out-of-equilibrium systems within the paradigm of turbulent front propagation. Usually, in this kind of issues, the attention is laid on the scale properties of objects, i.e. of their geometry, as for instance in fractal analysis.
