摘要

在带有显示透视伪影的粒子群的图像上直接叠加一个同等分的标准测试网格，往往会增加总体大小估计器的方差，因为样方内容变得不平衡。然而，如果按照影响粒子的相同投影机制对样方进行变换，则方差恢复为中等值。我们的目的是为相关变换提供精确的、易于编程的方程。

Transformation of a Grid of Quadrats to Cope With Perspective Artifacts

The direct superimposition of a standard test grid of congruent quadrats onto an image bearing a population of particles exhibiting perspective artifacts, tends to increase the variance of the population size estimator, because the quadrat contents become unbalanced. If the quadrats are transformed according to the same projection mechanism affecting the particles, however, then the variance is restored into moderate values. Our purpose was to provide exact, easily programmable equations for the relevant transform.

期刊介绍： Image Analysis and Stereology is the official journal of the International Society for Stereology & Image Analysis. It promotes the exchange of scientific, technical, organizational and other information on the quantitative analysis of data having a geometrical structure, including stereology, differential geometry, image analysis, image processing, mathematical morphology, stochastic geometry, statistics, pattern recognition, and related topics. The fields of application are not restricted and range from biomedicine, materials sciences and physics to geology and geography.
