Thermal imaging-based human emotion detection: GLCM feature extraction approach
No full textAbstract—Recent studies in artificial intelligence and robotics had
proved the ability of social intelligence in robots. However, it has
become increasingly apparent that social and interactive skills are
necessary requirements in any application areas and contexts where
robots need to interact and collaborate with other robots or humans. In
order to develop an emotionally intelligent robot, the issues on how to
perceive human affective states and how to manifest the robot’s
emotion should be addressed. In this paper, we presented an efficient
method for thermal image feature extraction using the Gray Level
Co-occurrence Matrix (GLCM) technique. By analysing the heat
pattern on the facial skin, this work attempt to investigate the
suitability of the thermal imaging technique for affect detection. The
findings of this study indicate thermal imaging as an alternative,
contactless and noninvasive method for appraising human emotional
states
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“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
MMU Cybertron from Multimedia University Cyberjaya
No full textThe theme for ROBOCON 2019 is Great Urtuu-Sharing the Knowledge. In participating in this competition, we are to design and construct two robots named the Messenger Robot 1 (MR1) and the Messenger Robot 2 (MR2). The MR1 robot will have three working omniwheels as its locomotion system, a short gripper supported by a short pole to hold the the Gerege and pick-up mechanism with a throwing mechanism in between. The MR2 robot consists of four mechanical legs attached to four motors. There is alos a small container fixed onto the body of the MR2 to hold the Gerege. Both robots must follow a stringent set of rules regarding the dimension, weight and other aspects
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
