Literature precedes the making of a film in most cases. The preparation for a movie is written in much details, be it for stories, scenes, dialogues, storyboards, or technical descriptions. In that extend, words are the genesis of cinema. Poetry is a unique way to express one＇s point of view in a metaphoric way, far from common means of communicating a message. This purpose is the one of many a film director with daring, controversial, or highly personal ideas. The study will concentrate on the link of cinema with poetry based on the concept of rhymes and rhythms.展开更多
The existing H.264/AVC rate control schemes rarely include the perceptual considerations.As a result,the im-provements in visual quality are hardly comparable to those in peak signal-to-noise ratio(PSNR).In this paper...The existing H.264/AVC rate control schemes rarely include the perceptual considerations.As a result,the im-provements in visual quality are hardly comparable to those in peak signal-to-noise ratio(PSNR).In this paper,we propose a perceptual importance analysis scheme to accurately abstract the spatial and temporal perceptual characteristics of video contents.Then we perform bit allocation at macroblock(MB)level by adopting a perceptual mode decision scheme,which adaptively updates the Lagrangian multiplier for mode decision according to the perceptual importance of each MB.Simulation results show that the proposed scheme can efficiently reduce bit rates without visual quality degradation.展开更多

Social networks have increased their public influence, which contain videotaped speeches and presentations. Multimodality has become a characteristic feature of contemporary political virtual communication. Bulgarian politicians appreciate the Internet as a tool for building popularity in its wealth of features, forms, and modes. Communicative tools and techniques have changed. The forms of the Bulgarian political communication found in the virtual environment such as sites, blogs, social networks, video clips, virtual forums, etc. are heterogeneous. Bulgarian citizens accept the Internet as a tool for increased political and social activities. Civil oratory, which is seen as a mechanism for efficient organizing of public events during election campaigns, protests, and demonstrations, is also present in the social networks. The citizens use a combination of verbal and visual elements; they are bloggers and participants in virtual political forums and actively participate in the spread of all kinds of forms of the social networks. They take part in the street demonstrations and organize performances; they ridicule politicians through posters and cartoons published online. Verbal and visual messages of the citizens come to real life during the protests and to virtual life in the social networks. The polyphony of social networks is a manifestation of virtual civil communication where the citizens in their virtual projection as netizens build up a new complex model of communication.展开更多
