Abstract

Παρέχεται μια συσκευή αποκωδικοποίησης ένδο-πρόβλεψης που αποκαθιστά τους ποσοτικοποιημένους υπολειπόμενους συντελεστές, τις πληροφορίες ένδο-πρόβλεψης και πληροφορίες μεγέθους σε μια μονάδα πρόβλεψης από ένα ληφθέν bit stream, αποκαθιστά μια κατάσταση ένδο-πρόβλεψης της τρέχουσας μονάδας πρόβλεψης επί τη βάση των πληροφοριών ένδο-πρόβλεψης και των πληροφοριών μεγέθους πάνω στην τρέχουσα μονάδα πρόβλεψης, παράγει μη διαθέσιμα pixel αναφοράς της μονάδας πρόβλεψης, και φιλτράρει με τρόπο προσαρμοστικό τα pixel αναφοράς επί τη βάση της κατάστασης ένδο-πρόβλεψης. Επίσης, η συσκευή παράγει ένα μπλοκ πρόβλεψης φιλτράροντας με τρόπο προσαρμοστικό pixel αναφοράς που αντιστοιχούν στην κατάσταση ένδο-πρόβλεψης. Στη συνέχεια, η συσκευή παράγει μια εικόνα επαναφοράς χρησιμοποιώντας το μπλοκ πρόβλεψης και ένα αποκατεστημένο υπολειπόμενο μπλοκ. Κατά ανάλογο τρόπο, ένα μπλοκ πρόβλεψης κοντά σε μια αρχική εικόνα, μπορεί να ανακτηθεί, και μια αναλογία συμπίεσης εικόνας, μπορεί να βελτιωθεί.
