Предлагаются алгоритмы автоматического выделения теней на полутоновых и цветных изображениях, основанные на анализе формы локальных гистограмм яркостей изображений. Алгоритмы устойчивы к сдвигам и растяжениям гистограмм. Они, в частности, позволяют получать удовлетворительные решения задачи выделения теней на аэрофотоснимках и космических изображениях, в том числе на тех, цветовые или яркостные характеристики которых различны в разных областях.
