Abstract

Μια μέθοδος κωδικοποίησης μιας εικόνας με τον σχηματισμό μιας ομάδας μονάδων πρόβλεψης σε έναν τομέα συχνοτήτων. Μια μονάδα πρόβλεψης μπορεί να προβλεφθεί με τη χρήση τιμών πρόβλεψης των μονάδων πρόβλεψης στην ομάδα των μονάδων πρόβλεψης, αντί για τα pixel που παράγονται με την κωδικοποίηση και στη συνέχεια επαναφορά των άλλων μονάδων πρόβλεψης στην ομάδα των μονάδων πρόβλεψης. Ως εκ τούτου, ένας λόγος συμπίεσης κωδικοποίησης μπορεί να αυξηθεί ως αποτέλεσμα της ομαδοποίησης των μονάδων πρόβλεψης.
