Abstract

Ένα προσαρμοστικό φίλτρο μετατόπισης (60) προσθέτει μια μετατόπιση στην τιμή εικονοστοιχείου κάθε εικονοστοιχείου που σχηματίζει μια εικόνα εισόδου. Το προσαρμοστικό φίλτρο μετατόπισης (60) αναφέρεται σε πληροφορίες καθορισμού του τύπου μετατόπισης, ορίζει τα ιδιοχαρακτηριστικά μετατόπισης για μια υποκείμενη μοναδιαία περιοχή της εικόνας εισόδου, αποκωδικοποιεί μια μετατόπιση που έχει ένα πλάτος δυαδικών ψηφίων που αντιστοιχεί σε ένα εύρος τιμών μετατόπισης που περιλαμβάνεται στα ορισμένα ιδιοχαρακτηριστικά μετατόπισης και προσθέτει την μετατόπιση στην τιμή εικονοστοιχείου κάθε εικονοστοιχείου που σχηματίζει την εικόνα εισόδου.
