An advantage of the proposed scheme is the use of perceptual color diﬀerence metrics to measure the distance between pixels, and the modiﬁcation of diﬀusion coefficients calculation formulas. Numerical simulation shows that the proposed scheme has a high quality and performance.</p></abstract><trans-abstract xml:lang="ru"><p>Рассматривается модификация классической модели Перона-Малика, адаптированная для фильтрации цветных дискретных изображений. Особенностью предлагаемой схемы является применение метрик перцептивного цветового различия для оценки расстояния между пикселями, а также модификаций подсчёта коэффициентов диффузии. Численное моделирование показывает, что предложенная схема обладает высоким качеством и производительностью.</p></trans-abstract><kwd-group xml:lang="en"><kwd>partial differential equations</kwd><kwd>Perona-Malik equation</kwd><kwd>image processing</kwd><kwd>image denoising</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дифференциальные уравнения в частных производных</kwd><kwd>схема Перона-Малика</kwd><kwd>обработка изображений</kwd><kwd>фильтрация изображений</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Hwu W.
