Суть предлагаемого метода заключается в вычислении градиентного изображения специального вида с использованием техники скользящего окна. В качестве степени различия, т. е. величины локального «градиента», могут использоваться точность классификации указанных выборок пикселей, взятых из двух половин окна, величина статистической значимости различий, получаемая с помощью теста Стьюдента, или результат сравнения выборок, полученный любым другим подходящим способом.</p></abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Inability of humans to discriminate between visual textures that agree in second-order statistics: revisited / B.
