    • Bant genişliği kısıtı altında videonun en iyi iletimi 

      Gürses, E.; Akar, G. B.; Akar, Nail (IEEE, 2006-04)
      In this paper, we propose an optimal video streaming framework using retransmissions based on the theory of Markov Decision Processes (MDP). Using MDPs, we calculate average reward optimal policies so as to maximize the ...
    • Haber videolarında nesne tanıma ve otomatik etiketleme 

      Baştan, Muhammet; Duygulu, Pınar (IEEE, 2006-04)
      We propose a new approach to object recognition problem motivated by the availability of large annotated image and video collections. Similar to translation from one language to another, this approach considers the object ...
    • Key frame selection from MPEG video data 

      Gerek, Ömer. N.; Altunbaşak, Y. (SPIE, 1997-02)
      This paper describes a method for selecting key frames by using a number of parameters extracted from the MPEG video stream. The parameters are directly extracted from the compressed video stream without decompression. A ...
    • Optimal packet scheduling and rate control for video streaming 

      Gürses, E.; Bozdağı-Akar, G.; Akar, Nail (SPIE, 2007)
      In this paper, we propose a new low-complexity retransmission based optimal video streaming and rate adaptation algorithm. The proposed OSRC (Optimal packet Scheduling and Rate Control) algorithm provides average reward ...
    • A simple and effective mechanism for stored video streaming with TCP transport and server-side adaptive frame discard 

      Gürses, E.; Akar, G. B.; Akar, N. (Elsevier, 2005)
      Transmission control protocol (TCP) with its well-established congestion control mechanism is the prevailing transport layer protocol for non-real time data in current Internet Protocol (IP) networks. It would be desirable ...
    • Uçtan uca modelleme ile kesintisiz stereo video iletimi 

      Tan, A. Serdar; Aksay, A; Akar, G. B.; Arıkan, Erdal (IEEE, 2008-04)
      Bu çalışmamızda, hata koruma yöntemi olarak oransız kodları (Raptor Kodları) kullanan kesintisiz bir stereo video iletim sistemi önermekteyiz. İlk olarak video kodlayıcının hızbozulum (HB) eğrisini ve kanal koruma kodunun ...
    • Unequal error protection for stereoscopic video streaming 

      Tan, Ahmet Serdar; Aksay, A.; Bilen, Ç.; Bozdağı-Akar, G.; Arıkan, Erdal (IEEE, 2007)
      The utilization of forward error correction (FEC) schemes for stereo video streaming is investigated. Stereo video is categorized in 3 layers and each layer is protected with different protection ratios for efficient ...
