Improving Pain Recognition Through Better Utilisation of Temporal Information
No full textAutomatically recognizing pain from video is a very useful application\ud
as it has the potential to alert carers to patients that are\ud
in discomfort who would otherwise not be able to communicate\ud
such emotion (i.e young children, patients in postoperative\ud
care etc.). In previous work [1], a “pain-no pain” system was\ud
developed which used an AAM-SVM approach to good effect.\ud
However, as with any task involving a large amount of video\ud
data, there are memory constraints that need to be adhered to\ud
and in the previous work this was compressing the temporal\ud
signal using K-means clustering in the training phase. In visual\ud
speech recognition, it is well known that the dynamics of the\ud
signal play a vital role in recognition. As pain recognition is\ud
very similar to the task of visual speech recognition (i.e. recognising\ud
visual facial actions), it is our belief that compressing\ud
the temporal signal reduces the likelihood of accurately recognising\ud
pain. In this paper, we show that by compressing the\ud
spatial signal instead of the temporal signal, we achieve better\ud
pain recognition. Our results show the importance of the temporal\ud
signal in recognizing pain, however, we do highlight some\ud
problems associated with doing this due to the randomness of a\ud
patient's facial actions
Patch-Based Analysis of Visual Speech From Multiple Views
No full textObtaining a robust feature representation of visual speech is\ud
of crucial importance in the design of audio-visual automatic\ud
speech recognition systems. In the literature, when visual\ud
appearance based features are employed for this purpose,\ud
they are typically extracted using a "holistic" approach.\ud
Namely, a transformation of the pixel values of the entire\ud
region-of-interest (ROI) is obtained, with the ROI covering\ud
the speaker's mouth and often surrounding facial area. In\ud
this paper, we instead consider a "patch" based visual feature\ud
extraction approach, within the appearance based framework.\ud
In particular, we conduct a novel analysis to determine which\ud
areas (patches) of the mouth ROI are the most informative for visual speech. Furthermore, we extend this analysis beyond\ud
the traditional frontal views, by investigating profile views\ud
as well. Not surprisingly, and for both frontal and profile\ud
views, we conclude that the central mouth patches are the\ud
most informative, but less so than the holistic features of the\ud
entire ROI. Nevertheless, fusion of holistic and the best patch\ud
based features further improves visual speech recognition\ud
performance, compared to either feature set alone. Finally,\ud
we discuss scenarios where the patch based approach may be\ud
preferable to holistic features
The death of William Golding: authorship and creativity in darkness visible and the paper men
Full text linkIn the seventies and eighties William Golding was deeply responsive to the critical, anti-authorial ethos that followed the publication of Roland Barthes's "La mort de I'auteur" (1968). In Darkness Visible (1979) and The Paper Men (1984) he investigates means by which to reaffirm authorial presence. Working through paradox, he performs the authorial death in these novels, and establishes language’s inadequacy as a means of conveying absolute meaning, authorial "vision," truth or revelation. Having done so he nonetheless gestures towards the divine, towards the possibility of a vatic communication. In this manner the novels work upon principles of contradiction and collapse. What remains is a discourse of hope, promise, desire, without means of substantiating such optimism. Thus Golding might be said to have practiced a form of negative theology, and to have anticipated in this respect some recent trends in literary theory
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Author-Illustrator
No full textThis essay investigates the concept author-illustrator by drawing on two influential essays – ‘Death of the Author’ by Roland Barthes and ‘What is an Author?’ by Michel Foucault. By engaging with the key points of debate that emerge from these positions, this essay argues that the notion of author-illustrator is part of a wider discursive field that is embedded in a complex, commodified, multimedia public sphere where the author is paradoxically reinscribed and erased. This environment is changing the nature of the text, authorship, and reader-text interaction, but until now the concept author-illustrator has been largely absent from these discussions
