Abstract
Texture being one of the main nuclear characteristics, there is a constant increase of methods for its quantification. As a better understanding of some textural parameters is needed, this study examined three methodological groups: analysis of grey level distributions (coefficients of variation, of skewness and of kurtosis), of the darkest or lightest points and of neighbored points like the cooccurrence matrix method. The discussion was done after an experimental study on three groups of real images (non-Hodgkin's lymphoma nuclei), representing three different textures (clumped, homogenous, fine chromatin. Of all the parameters analyzed, the coefficient of variation of nuclear brightness proved to be the best model of a textural variable.
Keywords : chromatin pattern, cooccurrence matrix, image analysis, quantitative microscopy, texture measurement
