Abstract

Un método de compresión de imagen con capacidad de acceso aleatorio. El método incluye intracodificar imágenes digitales. La imagen es dividida en pequeños bloques y cada bloque es codificado independientemente de otros bloques en la imagen. El codificador genera un número fijo y predeterminado de bits para cada bloque. La decodificación de cada bloque de imagen es capaz de hacerse independiente de cualquier otro bloque de imagen.
