    • Analog Joint Source Channel Coding for Image and Video Encoding and Transmission 

      Balsa, José (2022)
      [Resumo] Nos últimos anos aumentou significativamente o uso de dispositivos conectados a Internet, en particular os smartphones e os dispositivos de Internet of things (IoT). Estes últimos están experimentando un enorme ...

    • Analog Video Encoding and Quality Evaluation 

      Balsa, José; Fresnedo, Óscar; García-Naya, José A.; Domínguez-Bolaño, Tomás; Castedo, Luis (M D P I AG, 2019-07-23)
      [Abstract] The most widespread analog video encoding systems in the literature are based on the use of the 2D and 3D DCT. These systems use both transformations indistinctly without assessing their suitability. In this ...
