    • 3D Television - State of the art 

      Jaramillo Goñi, Mikel (Universitat Politècnica de Catalunya / AGH University of Science and Technology, 2012-03-24)
      Projecte/Treball Final de Carrera
      Accés obert
      Realitzat a/amb:   Akademia Górniczo-Hutnicza im. S. Staszica w Krakowie
      [ANGLÈS] Multiview videos are large and require a high bitrate for playback. The need to compress this type of information has made the development of a new compression method called multiview coding. This format uses the ...

    • Compressió geomètrica de núvols de punts amb MPEG G-PCC 

      Reguan Font, Roger (Universitat Politècnica de Catalunya, 2021-06)
      Treball Final de Grau
      Accés obert
      MPEG G-PCC (Geometric Point Cloud Compression) uses technologies like octrees, rasterization and arithmetic coding for compression for non-projectable 3D point clouds. A reference implementation is available as G-PCC Test ...

    • Depth based image segmentation 

      Morera Trujillo, Jordi (Universitat Politècnica de Catalunya, 2017-10-18)
      Treball Final de Grau
      Accés obert
      En este trabajo de fin de grado se exploran distintas técnicas de aprendizaje profundo (deep learning) con el objetivo de obtener una segmentación de imagen basada en criterios de uniformidad. Estudiamos varios algoritmos ...

    • Depth map coding based on a hierarchical region representation combining color and depth information 

      Maceira Duch, Marc (Universitat Politècnica de Catalunya, 2013-06)
      Projecte Final de Màster Oficial
      Accés obert
      [ANGLÈS] The growing interest in 3D television had created new needs of storing the information related with 3D views. 3D video coding includes the use of multiple color views and depth maps associated to each view. An ...

    • Estudio de viabilidad técnica e implementación de un sistema de transmisión de video adaptativo H264/SVC sobre TCP 

      Grau Gracia, Manel (Universitat Politècnica de Catalunya, 2014-06)
      Projecte/Treball Final de Carrera
      Accés obert
      [ANGLÈS] H264/SVC video system development adaptive to network connections. In order to become adaptive, it has been done the necessary bandwidth monitoring in order to could transmit up to one of the possible extraction ...

    • Interactive Video Coding 

      Colom Serra, Aleix (Universitat Politècnica de Catalunya / Linköping University, 2013-09-05)
      Treball Final de Grau
      Accés obert
      [ANGLÈS] One of the main challenges when transcoding video is to find a proper balance between good quality and a manageable final size of the video file. A possible solution is to perform a trial and error procedure, ...
