Novel approach to determining tempo and dramatic story sections in motion pictures
This paper presents an original computational approach to extraction of movie tempo for deriving story sections and events that convey high level semantics of stories portrayed in motion pictures, thus enabling better video annotation and interpretation systems. This approach, inspired by the existing cinematic conventions known as film grammar, uses the attributes of motion and shot length to define and compute a novel continuous measure of tempo of a movie. Tempo flow plots are derived for several full-length motion pictures and edge detection is performed to extract dramatic story sections and events occurring in the movie, underlined by their unique tempo. The results confirm reliable detection of actual distinct tempo changes and serve as useful index into the dramatic development and narration of the story in motion pictures
Scene extraction in motion pictures
This paper addresses the challenge of bridging the semantic gap between the rich meaning users desire when they query to locate and browse media and the shallowness of media descriptions that can be computed in today\u27s content management systems. To facilitate high-level semantics-based content annotation and interpretation, we tackle the problem of automatic decomposition of motion pictures into meaningful story units, namely scenes. Since a scene is a complicated and subjective concept, we first propose guidelines from fill production to determine when a scene change occurs. We then investigate different rules and conventions followed as part of Fill Grammar that would guide and shape an algorithmic solution for determining a scene. Two different techniques using intershot analysis are proposed as solutions in this paper. In addition, we present different refinement mechanisms, such as film-punctuation detection founded on Film Grammar, to further improve the results. These refinement techniques demonstrate significant improvements in overall performance. Furthermore, we analyze errors in the context of film-production techniques, which offer useful insights into the limitations of our method
Toward automatic extraction of expressive elements from motion pictures : tempo
This paper addresses the challenge of bridging the semantic gap that exists between the simplicity of features that can be currently computed in automated content indexing systems and the richness of semantics in user queries posed for media search and retrieval. It proposes a unique computational approach to extraction of expressive elements of motion pictures for deriving high-level semantics of stories portrayed, thus enabling rich video annotation and interpretation. This approach, motivated and directed by the existing cinematic conventions known as film grammar, as a first step toward demonstrating its effectiveness, uses the attributes of motion and shot length to define and compute a novel measure of tempo of a movie. Tempo flow plots are defined and derived for a number of full-length movies and edge analysis is performed leading to the extraction of dramatic story sections and events signaled by their unique tempo. The results confirm tempo as a useful high-level semantic construct in its own right and a promising component of others such as rhythm, tone or mood of a film. In addition to the development of this computable tempo measure, a study is conducted as to the usefulness of biasing it toward either of its constituents, namely, motion or shot length. Finally, a refinement is made to the shot length normalizing mechanism, driven by the peculiar characteristics of shot length distribution exhibited by movies. Results of these additional studies, and possible applications and limitations are discussed
Automated film rhythm extraction for scene analysis
This paper examines film rhythm, an important expressive element in motion pictures, based on our ongoing study to exploit film grammar as a broad computational framework for the task of automated film and video understanding. Of the many, more or less elusive, narrative devices contributing to film rhythm, this paper discusses motion characteristics that form the basis of our analysis, and presents novel computational models for extracting rhythmic patterns induced through a perception of motion. In our rhythm model, motion behaviour is classified as being either nonexistent, fluid or staccato for a given shot. Shot neighbourhoods in movies are then grouped by proportional makeup of these motion behavioural classes to yield seven high-level rhythmic arrangements that prove to be adept at indicating likely scene content (e.g. dialogue or chase sequence) in our experiments. Underlying causes for this level of codification in our approach are postulated from film grammar, and are accompanied by detailed demonstration from real movies for the purposes of clarification.<br /

On the extraction of thematic and dramatic functions of content in educational videos
In this paper, we propose novel computational models for the extraction of high level expressive constructs related to, namely thematic and dramatic functions of the content shown in educational and training videos. Drawing on the existing knowledge of film theory, and media production rules and conventions used by the filmmakers. we hypothesize key aesthetic elements contributing to convey these functions of the content. Computational models to extract them are then formulated and their performance evaluated on a set of ten educational and training videos is presented.<br /

Musical Mimesis in Orphans of the Storm
In this essay I explore the use of musical mimesis in the score for D. W. Griffith’s 1921 film Orphans of the Storm. I demonstrate that the score, created by Louis F. Gottschalk and William Frederick Peters, offers coherence through the use of central themes and the employment of several characteristic leitmotivs; provides recognizable musical characterizations of emotions and physical phenomena, establishing a consistent mimetic aspect to the music; and reflects the structure of the film as a whole
Narrative structure detection through audio pace
We use the concept of film pace, expressed through the audio, to analyse the broad level narrative structure of film. The narrative structure is divided into visual narration, action sections, and audio narration, plot development sections. We hypothesise, that changes in the narrative structure signal a change in audio content, which is reflected by a change in audio pace. We test this hypothesis using a number of audio feature functions, that reflect the audio pace, to detect changes in narrative structure for 8 films of varying genres. The properties of the energy were then used to determine the. audio pace feature corresponding to the narrative, structure for each film analysed. The method was successful in determining the narrative structure for 1 of the films, achieving an overall precision of 76.4% and recall of 80.3%, We map the properties of the speech and energy of film audio to the higher level semantic concept of audio pace. The audio pace was in turn applied to a higher level semantic analysis of the structure of film.<br /
Subversive blood ties: gothic decadence in three characters from murnau's and coppola's renderings of bram stoker's dracula
Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e ExpressĂŁo, Programa de PĂłs-Graduação em Letras/InglĂŞs e Literatura Correspondente, FlorianĂłpolis, 2013Esta dissertação consiste em investigar a construção do tema da decadĂŞncia GĂłtica em Drácula de Bram Stoker e duas adaptações fĂlmicas do romance - Nosferatu, de Friedrich Wilhelm Murnau, e Drácula de Bram Stoker, de Francis Ford Coppola - tendo como centro da análise como trĂŞs personagens - Drácula, Jonathan Harker e Mina Harker - se relacionam com tal tema. A decadĂŞncia GĂłtica Ă© um padrĂŁo literário do contexto fin-de-siècle da sociedade vitoriana inspirada pela crise social que acontecia na Inglaterra no fim do sĂ©culo XIX (Punter e Byron 39-40). Autores como Bram Stoker escreveram histĂłrias que refletiam medos morais e sociais da sociedade vitoriana, retratando imagens de monstros que representavam a transgressĂŁo de fronteiras morais e sexuais estabelecidas pelas tradições vitorianas (Botting 88). Tendo tal discussĂŁo em mente, este estudo busca conectar a retratação de tal tema do romance Ă s adaptações, tambĂ©m utilizando uma análise fĂlmica para identificar tĂ©cnicas que destacam a representação do tema relacionado aos trĂŞs personagens, finalmente ligando tal tema a crises e confusões sociais que aconteciam nos contextos de ambos os filmes.Abstract : The present dissertation consists of an investigation of the construction of the Gothic theme of decadence in Bram Stoker's Dracula and two film adaptations of the novel - Friedrich Wilhelm Murnau's Nosferatu and Francis Ford Coppola's Bram Stoker's Dracula - having as the centre of analysis how three characters - Dracula, Jonathan Harker and Mina Harker - relate to that theme. The Gothic decadence is a literary motif from the fin-de-siècle context of the Victorian Era inspired by the social crisis that took place in England in the late nineteenth century (Punter and Byron 39-40). Authors like Bram Stoker wrote stories that reflected moral and social fears of the Victorian society, depicting images of monsters that represented the crossing of moral and sexual boundaries established by the Victorian traditions (Botting 88). Bearing that discussion in mind, this study aims at connecting the portrayal of such a theme from novel to the two adaptations, also making use of a filmic analysis to identify techniques that highlight the depiction of the theme related to the three characters, ultimately linking such a thematic depiction to crises and social commotions that were taking place in both films' social contexts
