Abstract

Se describe un método que decodifica una imagen en una forma de una corriente de bitios. La imagen es codificada y representada por vectores de coeficientes. Cada coeficiente está en una forma cuantificada. Se selecciona un coeficiente específico en cada vector en base en un orden de exploración del vector. Después se infieren un conjunto de modos en base en características del coeficiente específico. Subsecuentemente, la corriente de bitios es decodificada de acuerdo con el conjunto de modos.
