    • Error resilient layered stereoscopic video streaming 

      Tan, A. S.; Aksay, A.; Bilen, C.; Akar, G. B.; Arikan, E. (2007)
      In this paper, error resilient stereoscopic video streaming problem is addressed. Two different Forward Error Correction (FEC) codes namely Systematic LT and RS codes are utilized to protect the stereoscopic video data ...
    • Key frame selection from MPEG video data 

      Gerek O.N.; Altunbasak, Y. (1997)
      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 ...
    • Object recognition and auto-annotation in news videos 

      Baştan, M.; Duygulu P. (2006)
      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 ...
    • Optimal packet scheduling and rate control for video streaming 

      Gürses, E.; Akar G.B.; Akar, N. (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 ...
    • Optimal streaming under rate constraints (İngilizce) 

      Gurses, E.; Akar G.B.; Akar, N. (2006)
      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 ...
    • 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 ...
    • Stereoscopic video streaming with end-to-end modeling 

      Tan, A.S.; Aksay, A.; Akar G.B.; Arikan, E. (2008)
      In this work, we propose a stereoscopic video streaming system that uses rateless codes (Raptor codes) as the error protection scheme. Initially, we model the rate-distortion (RD) curve of video encoder and performance of ...
    • Unequal error protection for stereoscopic video streaming 

      Tan, A.S.; Aksay, A.; Bilen Ç.; Akar G.B.; Arikan, E. (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 ...
