Предлагается блочный алгоритм быстрого сжатия изображений без потерь с пространственно-кодовой адаптацией, основанный на использовании двухпороговой маски предсказания с установленными порогами, адаптивно-блочного кодирования Голомба – Райса и снижения избыточности с помощью коэффициента относительного изменения параметра кода Голомба – Райса. Результаты моделирования алгоритма для полутоновых и цветных изображений показали высокую эффективность сжатия (1,6–1,75) при низкой вычислительной сложности.
