Abstract

Video verilerinin imge bölgesinin sınırlarını belirlemeye yönelik bır yöntem sağlanmaktadır. Bu yöntem bir veri kaynağından ardışık tarama düzeninde bir video verileri çerçevesinin piksel verilerinin alınmasını içerir. Bu yöntem ayrıca her bir pikselin ardışık tarama yönüne dik ya da dike yakın bir kenarı olan bir kenar bölgesine bitişik olup olmadığının saptanması için, sözü edilen çerçevenin en azından bazı piksellerinin piksel verileri üzerinde ardışık tarama düzeninde kenar saptaması yapılmasını içerir. Bundan sonra, dikey kenar saptamasından sözü edilen çerçevenin imge bölgesinin sınırlarının belirlenir. Böyle bir yöntem sağlayarak, bir kaynaktan (örneğin bir TV anteni ya da bir ortam yürütücüsü) ardışık tarama düzeninde veri alındıkça, piksel verileri imge sınırlarını saptamak üzere işlenebilir.Bu,örneğin bir imge işleme çalışması öncesinde imge sınırlarının saptanmasına etkin bir yaklaşım sağlar.
