Abstract

Sposób wyznaczania predyktora wektora ruchu MVPRED, polega na tym, ze po ustaleniu bloku predykcji PUX(1) wyszukuje sie dla tego bloku predykcji PUX zrekonstruowany sasiedni blok predykcji PUY w zrekonstruowanej czesci sekwencji (2), nastepnie sprawdza sie czy blok PUY nie byt zakodowany w trybie skip a jednoczesnie byl zakodowany w trybie merge(3), w przypadku gdy opisany test ma wynik pozytywny to dla bloku punktów rekonstrukcji obrazu, odpowiadajacemu blokowi PUY, przeprowadza sie wyszukiwanie wektora ruchu MVPUYrek(4), po czym znaleziony wektor ruchu MVPUYrek przypisuje sie do bloku PUY zamiast jego wektora ruchu MV(5), nastepnie, niezaleznie od wyniku porównania (3) wektor MV bloku PUY przypisuje sie do bloku PUX jako predyktor wektora ruchu MVPRED(6), co konczy (7) wyszukiwanie predyktora wektora ruchu.
