Abstract

Предложен способ кодирования цветовых величин элементов изображения для блоков цифровых данных видеоизображения, в котором каждому отличающемуся от других цвету в изображении назначают цветовую величину. Преобладающий цвет идентифицируют для блока данных изображения и, в первом осуществлении, каждый элемент изображения, имеющий цвет, не являющийся преобладающим цветом, отдельно кодируют как его соответствующую цветовую величину (0010 до 1111) с помощью прогонов из трех или более следующих один за другим элементов изображения преобладающего цвета, кодируемых по длине прогона. Дополнительный код (0000 0011 сссс), аналогичный по выполнению коду указания прогона, обеспечивают, чтобы сделать возможным изменение в заданном преобладающем цвете в ходе блока данных. В другом осуществлении прогоны всех цветов кодируют по длине прогона, но с помощью более короткой схемы кодирования для прогонов преобладающего цвета, или, еще в одном осуществлении, небольшого диапазона преобладающих цветов. Основным применением для этих схем кодирования является повышение производительности кодирования для определения классов материала изображения. Отчет о международном поиске опубликован 10.10.96.
