Задача синтеза решается с помощью метода множителей Лагранжа. Показано, что Q-ПУБФ представляет собой целочисленное преобразование и может быть использовано для кодирования изображений по схеме L2L (lossless-to-lossy).</p></abstract><trans-abstract xml:lang="en"><p>The synthesis method of paraunitary filter banks based on the quaternion algebra (Q-PUBF) for computing structures constrained by fixed point arithmetic is proposed.
