Abstract

Bir rekursif arama yöntemi kullanılarak bir ilen hareket vektör alanının (MVF_fw) ve bir geri hareket vektör alanının (MVF_bw) güncellenmesi, minimum mutlak fark toplamı değerine sahip olan hareket vektör alanı seçilerek ve seçilen vektör alanına bağlı bir vektör alan bir pürüzsüzlük parametresi eklenerek güncellenmiş hareket vektörlerinın (MVF_fw_upd, MVF_bw_upd) birleştirilmesi adımlarını içeren, video uygulamaları için görüntü karesi artırımında bir ıleri-geri hareket kestirim yöntemidir Bu yöntemde, pürüzsüzlük parametresini hesaplamak için güncellenecek bloğun komşu blokları kullanılır Böylece bu yöntemle daha pürüzsüz bir hareket vektör alanı üretilir.
