Abstract

Hareket vektör alanı yemden zamanlandırması özelikle çerçeve hızı artırımı uygulamalannda hareket telafili enterpolasyon ıçın en yaygın yöntemdir Ancak, yanlış hareket tahmini nedeniyle nesne-hareket sımrian uzenndekı oklüzyon bölgelennde ağıl sorunlan meydana gelir. Dolayısıyla, enterpole edilecek çerçevenin zamansal yerleşiminde bulunan bir hareket vektör alanı elde etmek ıçın güvenilir bir yeniden zamanlandınlmış hareket vektör alanına ihtiyaç duyulur Mevcut buluşta, yem bır hareket vektör alanı yemden zamanlandırma yöntemi anlatılmaktadır. Bahsedilen yönteme göre, önceki hareket vektör alanı (fp) ve sonraki hareket vektör alanı (fp+ı) ıçın, FG (3) - BG (4) aynştırma metriği hesaplanır. Hesaplanan ayrıştırma metnğine gore, onceki hareket vektör alanının (fp) ilen doğrultudaki (101) izdüşümü ve sonraki hareket vektör alanının (fn+ı) geri doğrultudaki (102) ızduşumu yapılır Bahsedilen ızduşumu yapılmış vektorier 15 (101, 102), onceki çerçeve (fp) ve sonraki çerçeve (fp+ı) arasında enterpole edilen bır hareket vektör alanı meydana getmr. FG (3) - BG (4) ayrıştırma metriği önceki çerçeve (fn) ve sonraki çerçevedeki (fn+ı) hareket vektör alanlarının ızduşümuyle kullanılarak ağıl sorunlan çözülür
