Shape analysis based on depth-ordering
In this paper we propose a new method for shape analysis based on the ordering of shapes using band-depth. We use this band-depth to non-parametrically define a global depth for a shape with respect to a reference population, typically consisting of normal control subjects. This allows us to globally quantify differences with respect to "normality". Using the depth-ordering of shapes also allow...
متن کاملDepth-Based Shape-Analysis
In this paper we propose a new method for shape analysis based on the depth-ordering of shapes. We use this depth-ordering to non-parametrically define depth with respect to a normal control population. This allows us to quantify differences with respect to "normality". We combine this approach with a permutation test allowing it to test for localized shape differences. The method is evaluated ...
متن کاملRunning head: OBJECT COLOR ON DEPTH ORDERING THE EFFECT OF OBJECT COLOR ON DEPTH ORDERING
The relationship between color and perceived depth for realistic, colored objects with varying shading was explored. Background: Studies have shown that warm-colored stimuli tend to appear nearer in depth than cool-colored stimuli. The majority of these studies asked human observers to view physically equidistant, colored stimuli and compare them for relative depth. However, in most cases, the ...
متن کاملShape - Wilf - Ordering on Permutations of Length
The research on pattern-avoidance has yielded so far limited knowledge on Wilf-ordering of permutations. The Stanley-Wilf limits limn→∞ n √ |Sn(τ )| and further works suggest asymptotic ordering of layered versus monotone patterns. Yet, Bóna has provided essentially the only known up to now result of its type on ordering of permutations: |Sn(1342)| < |Sn(1234)| < |Sn(1324)| for n ≥ 7. We give a...
متن کاملdepth-based nonparametric multivariate analysis and its application in review of new treatment methodology on osteoarthrotic
In this article, first, we introduce depth function as a function for center-outward ranking. Then we present and use half space or Tukey depth function as one of the most popular depth functions. In the following, multivariate nonparametric tests for location and scale difference between two population are expressed by ranking and statistics based on depth versus depth plot. Finally, accord...
