This paper introduces our recent research work on the development of a scalable foveated visual information coding and communication system, which follows two emerging trends in visual communication research. One is to design rate scalable image and video codecs, which allow the extraction of coded visual information at continuously varying bit rates from a single compressed bitstream. The othe...

Despite early and ongoing calls for a systematic engagement with history, social semiotics has largely emphasized research on the synchronic rather than diachronic dimensions of meaning-making. And while ‘instability’ semiotic practices (see Kress’s Multimodality: A Social Semiotic Approach to Contemporary Communication, 2010) importance change Van Leeuwen’s Introducing Semiotics, 2005) have be...
