The nucleator is a well-established manual stereological method of estimating mean cell volume from observations on random cell transects through reference points of the cells. In this paper, we present an automated version of the nucleator that uses automatic segmentation of the boundaries of the cell transects. An expert supervises the process. If the(More)
In the present study the Hamilton Anxiety Scale (HAS), originally constructed for patients with neurotic anxiety, has been applied to patients with diagnosis of depressive disorders. The inter-rater reliability and homogeneity are evaluated and total scale score has been correlated to the Bech-Rafaelsen Melancholia Scale (BRMES). Twenty-two patients entered(More)
37 alcoholic males under the age of 35 were examined clinically, by psychometric tests, by computerised tomography (CT scans), and by liver biopsy. Factors other than alcoholism that might have caused brain damage were excluded. The prevalence of brain damage in this group was far greater than that of severe liver damage: 59% were intellectually impaired(More)
A model for an inhomogeneous Poisson process with high intensity near the edges of a Voronoi tessellation in 2D or 3D is proposed. The model is analysed in a Bayesian setting with priors on nuclei of the Voronoi tessellation and other model parameters. An MCMC algorithm is constructed to sample from the posterior, which contains information about the(More)
We propose a new statistical method for obtaining information about particle size distributions from sectional data without specific assumptions about particle shape. The method utilizes recent advances in local stereology. We show how to estimate separately from sectional data the variance due to the local stereological estimation procedure and the(More)
This paper suggests a high-level continuous image model for planar star-shaped objects. Under this model, a planar object is a stochastic deformation of a star-shaped template. The residual process, describing the difference between the radius-vector function of the template and the object, is allowed to be non-stationary. Stationarity is obtained by a time(More)
The orientational characteristics of fibres in digital images are studied. The fibres are modelled by a planar Boolean model whose typical grain is a thick (coloured) fibre. The aim is to make stereological inference on the rose of directions of the unobservable central fibres from observations made on a digital image of the thick fibres. For central(More)
In the present paper, we describe new robust methods of estimating cell shape and orientation in 3D from sections. The descriptors of 3D cell shape and orientation are based on volume tensors which are used to construct an ellipsoid, the Miles ellipsoid, approximating the average cell shape and orientation in 3D. The estimators of volume tensors are based(More)
