Fusion-features and visual-dictionary image recognition methods for apple classification in smart manufacturing / Ahsiah Ismail
Smart manufacturing enables an efficient manufacturing process to optimize
production. The optimization is performed through data analytics that requires reliable
and informative data as input. Therefore, in this research, two image recognition feature
extraction methods namely Curvelet Wavelet-Gray Level Co-occurrence Matrix (CWGLCM)
and Fuzzy-Spatial Pyramid Matching (F-SPM) are proposed to provide reliable
inputs for vision-based apple classification in smart manufacturing. Feature extraction is
one of the major steps that could influent the efficiency of the manufacturing process.
The CW-GLCM method is a feature extraction of fusion-features with Decision Tree
classifier, while the F-SPM method uses a visual-dictionary based method to extract
features of visual pattern and the output is process by Support Vector Machine (SVM)
classifier. To evaluate the performance of the proposed methods, they are compared with
five existing methods, which are Bag of Words (BOW), Spatial Pyramid Matching
(SPM), Gray Level Co-occurrence Matrix (GLCM) Texture analysis, Convolutional
Neural Network (CNN) and Contrast‐Limited Adaptive Histogram Equalization + GLCM
+ Extreme Learning Machine (CLAHE+GLCM+ELM). Three datasets which are NDDA,
NDDAW and DA datasets with a total of 1310 apple images are collected to test the
proposed methods. The NDDA and NDDAW datasets are both binary-class of defective
and non-defective apple dataset, with NDDAW contains more low-quality region images
compared to the NDDA. Conversely, the DA dataset comprised of five different types of
defective apples to be used in multi-class tests. The proposed methods are trained and
evaluated using 10-fold cross-validation. Their classification accuracy, precision and
recall rate are then measured. Training and testing times are also recorded. From the
evaluation, the proposed F-SPM method attained 98.15% classification accuracy, 96.30% precision and 100% recall for NDDA, 91.07% for accuracy, 100% precision and 84.85%
recall for NDDAW, 86.33% for accuracy, 91.43% precision and 85.00% recall for DA
dataset. The F-SPM method outperformed the existing methods especially for NDDAW
and DA datasets. Alternatively, the CW-GLCM method able to obtain 98.15% accuracy,
96.30% precision and 100% recall for NDDA, 89.11% accuracy, 86.79% precision and
91.01% recall for NDDAW, 85.20% of accuracy, 88.33% precision and 85.00% recall for
DA dataset. The proposed CW-GLCM also shows the highest percentage (100%) for all
measurements (accuracy, precision and recall) and it even outperform others in
recognizing the Bruise defect. These results indicate that both proposed methods are
reliable and have the potential to be used for vision classification in smart manufacturing
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
We 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
