Abstract (2. Language): 
In this paper, the task of synthesizing virtual music without adopting any musical instruments has been accomplished by detecting the changes in hand position with the help of computer vision techniques. The melody of one octave has been studied taking the possible diversities in the number of fingers into consideration. Vocalizing proper notes corresponding to the current hand position has been carried out through computerized interpretation of finger motions on a hand image recorded by a video camera. Finger positions have been determined by preprocessing the input hand image. Feature vector has been composed of the distances from hand's center of gravity to finger tips. As a result, the feasibility of real-time computerized synthesis of virtual music has been demonstrated by evaluating the finger motions without the need for heavy musical instruments such as piano.

Abstract (Original Language): 
(Çalışmada çalgı aleti kullanılmadan, bilgisayarlı görü yardımıyla el durumunun (parmakların) değişimi algılanarak sanal müzik çalınması incelenmektedir. Parmak sayısının oluşturabileceği çesitlilikler göz önünde bulundurularak sesin notaya dayalı melodisi üzerinde durulmustur. Kamera yardımıyla alınan el görüntüsündeki parmak hareketleri bilgisayarda yorumlanarak uygun notaların seslendirilmesi sağlanmıstır. Özellik vektörü olarak el yapısının agırlık merkezine güre parmak uçlarına olan uzaklıkların degerlendi-rilmesi gerçeklestirilmistir. Boylelikle parmak hareketleri yorumlanarak piyano gibi agır aletleri tasımadan bilgisayarda gerçek zamanlı müzik seslendirilmesinin mumkünluğu güs-terilmiçstir.
