Geometry-enhanced attentive multi-view stereo for challenging matching scenarios
No full textDeep networks have made remarkable progress in Multi-View Stereo (MVS) task in recent years. However, the problem of finding accurate correspondences across different views under ill-posed matching situations remains unresolved and crucial. To address this issue, this paper proposes a Geometryenhanced Attentive Multi-View Stereo (GA-MVS) network, which can access multi-view consistent feature representation and achieve accurate depth estimation in challenging situations. Specifically, we propose a geometry-enhanced feature extractor to explore illumination-invariant geometric features and incorporate them with common texture features to improve matching accuracy when dealing with view-dependent photometric effects, such as shadow and specularity. Then, we design a novel attentive learning framework to explore per-pixel adaptive supervision, effectively improving the depth estimation performance of textureless regions. The experimental results on the DTU and Tanks & Temples benchmarks demonstrate that our method achieves state-of-the-art results compared to other advanced MVS models
Dysteria monostyla Kahl 1931
No full textDysteria monostyla (Ehrenberg, 1838) Kahl, 1931 (Fig. 5 A–E; Table 2) Morphological description. Body 40–70 × 30–45 µm in vivo, rectangular to oval in side view (Fig. 5A). Two ventrally located contractile vacuoles, one at anterior 1/3 and the other at posterior 1/4 of cell, each with a diameter of about 4 μm and a pulsating interval of about 15 s (Fig. 5A). Two nematodesmal rods, each about 25 μm long. Macronucleus ellipsoidal and heteromerous, about 25 × 15 μm in vivo and about 25 × 13 μm after protargol staining (Fig. 5E). Micronucleus not detected. Podite about 12 µm long. Cell surface densely covered by bar-shaped ectosymbiotic bacteria (about 4 μm long; Fig. 5B). Fine transverse stripes at mid-body on surface of both lateral plates (Fig. 5B). Invariably five right kineties with densely arranged basal bodies including two frontoventral kineties with 119–128 basal bodies each (Fig. 5C). Five to eight left kineties (Fig. 5E). Terminal fragment consists of 9–11 basal bodies (Fig. 5C). Equatorial fragment composed of 5–19 kinetosomes (Fig. 5C). Oral apparatus typical of genus (Fig. 5D). SSU rRNA gene sequence and phylogenetic position. The GenBank accession number, length, and G + C content are MK 882888, 1,677 bp, and 44.25%, respectively. The closest related Dysteria species is Dysteria compressa (KC 753491) with a 99.8% sequence similarity. In phylogenetic trees (Fig. 6), D. monostyla first groups with D. compressa KC753491, then clusters with D. brasiliensis FJ870067 with high support values (ML /BI, 99%/1.00).Published as part of Wang, Congcong, Qu, Zhishuai & Hu, Xiaozhong, 2019, Morphology and SSU rDNA sequences of four cyrtophorian ciliates from China, with description of a new species (Protista, Ciliophora, Phyllopharyngea), pp. 206-220 in Zootaxa 4664 (2) on pages 212-213, DOI: 10.11646/zootaxa.4664.2.3, http://zenodo.org/record/338453
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
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
