Bias in image analysis and its solution: unbiased stereology

Bias in image analysis and its solution: unbiased stereology

Although the human eye is excellent for pattern recognition, it often lacks the sensitivity to detect subtle changes in particle density. Because of this, quantitative evaluation may be required in some studies. A common type of quantitative assessment used for routine toxicology studies is two-dimensional histomorphometry. Although this technique can provide additional information about the ti...

Extending Unbiased Stereology of Brain Ultrastructure to Three-dimensional Volumes

Design and Measurements: Volumes are reconstructed by defining transformations that align the entire area of adjacent sections. Whole-field alignment requires rotation, translation, skew, scaling, and second-order nonlinear deformations. Such transformations are implemented by a linear combination of bivariate polynomials. Computer software for generating transformations based on user input is ...

Unbiased equation error identification and approximations: a frequency-domain solution and its performance analysis

We consider a frequency-domain solution to the leastsquares equation error identi cation problem using the power spectrum and the cross-spectrum of the IO (inputoutput) data to estimate the IO parametric transfer function. The proposed approach is shown to yield a unimodal performance surface, consistent identi cation in colored noise and su cient-order case, and stable tted models under underm...
