Franklin and McDermid (1993) and Franklin et al. (1996) proposed an alternative technique: a geographic window, where dimensions of a moving kernel are customized and are determined by variogram range. The technique proved to be promising and has been applied to derive texture measures like the co-occurrence matrix for image classification as well as first and second order texture and semivariance moment texture (nugget, range, sill, slope, mean semivariance) for LAI [Leaf Area Index] estimation (Wulder et al. 1997). 2, record 1, English, - variogram%20slope

Le variogramme est le plus souvent croissant, c'est-à-dire que les variations radiométriques sont statistiquement plus importantes sur n+1 pixels que sur n pixels. La pente du variogramme est un critère de rugosité : une pente forte caractérise un signal «lisse», sans transitions brutales, tandis qu'une pente faible caractérise un signal «accidenté». Une surface dont le variogramme a une pente constante présente la même texture à toutes les échelles. On dit qu'elle est auto-similaire ou fractale. 1, record 1, French, - pente%20de%20variogramme

You need not be a statistician to make good use of geostatistics, but you may need the assistance, support, guidance of a (geo) statistician. A good engineer, ecologist, biologist, plant scientist, hydrologist, soil physicist already has a good start, because geostatistics is only good science brought up to date by the recognition that natural phenomena are subject to spatial variation. 4, record 2, English, - variogram

Une fractale, selon Mandelbrot, «est une forme constituée d’éléments similaires à l’ensemble, d’une certaine façon». Cela signifie que les fractales sont auto-similaires, ou invariantes par dilatation d’échelle, c’est-à-dire que l’aspect de l’une de leurs parties, convenablement agrandie, est semblable au tout [...] 3, record 3, French, - fractale%20autosimilaire
