“…In addition to the need mentioned above for a facial image, it play a vital……role in (E-Gov) applications such submitting of individuals for jobs, paying tax, social benefit, driving license, e-passport and national cards. Basically that comes with a greater storage cost, because of huge bytes consumptions overloaded with image redundancy(s), even all the images overloaded are compressed in the standard format of well-known efficient JPEG ( Joint Photographic Experts Group) techniques, but still suffer from inherited problems of inability to consider image regions independently, and block-based nature [1]- [5]. Passport photo image compression generally represents the significant facial information compactly, while losing insignificant information of redundancy base, in which the techniques mainly classified either according to the redundancy removal of lossless and lossy scheme or the domain of removal that implies spatial coding (SC), Transformation Coding (TC) and Hybrid coding (HC) , figure (1) shows the categorized clearly.…”

“…Αυτή η μέτρηση πραγματοποιείται μέσω της χρήσης ενός κριτηρίου σφάλματος μεταξύ του προβλεπόμενου και του πραγματικού block, όπως το μέσο τετραγωνικό σφάλμα (mean squared error -MSE), και άλλων μεθόδων μέτρησης. Πράγματι, η ίδια η έννοια της αντιστάθμισης κίνησης, όπως αυτή χρησιμοποιείται στην κωδικοποίηση βίντεο, βασίζεται στην υπόθεση ότι το block αναφοράς μπορεί να προσεγγιστεί με ακρίβεια από μία μετατοπισμένη εκδοχή του block στόχου [1,5,17,67]…”
