Capturing Conversational Gestures for Embodied Conversational Agents Using an Optimized Kaneda–Lucas–Tomasi Tracker and Denavit–Hartenberg-Based Kinematic Model
Grega Močnik, Zdravko Kačič, Riko Šafarič, Izidor Mlakar, 2022, original scientific article

Abstract: In order to recreate viable and human-like conversational responses, the artificial entity, i.e., an embodied conversational agent, must express correlated speech (verbal) and gestures (non-verbal) responses in spoken social interaction. Most of the existing frameworks focus on intent planning and behavior planning. The realization, however, is left to a limited set of static 3D representations of conversational expressions. In addition to functional and semantic synchrony between verbal and non-verbal signals, the final believability of the displayed expression is sculpted by the physical realization of non-verbal expressions. A major challenge of most conversational systems capable of reproducing gestures is the diversity in expressiveness. In this paper, we propose a method for capturing gestures automatically from videos and transforming them into 3D representations stored as part of the conversational agent’s repository of motor skills. The main advantage of the proposed method is ensuring the naturalness of the embodied conversational agent’s gestures, which results in a higher quality of human-computer interaction. The method is based on a Kanade–Lucas–Tomasi tracker, a Savitzky–Golay filter, a Denavit–Hartenberg-based kinematic model and the EVA framework. Furthermore, we designed an objective method based on cosine similarity instead of a subjective evaluation of synthesized movement. The proposed method resulted in a 96% similarity.

Revitalization and valorization of Onogošt fortress in Nikšić : master thesis
Đina Prnjat, 2021, master's thesis

Abstract: Fortress "Onogošt", known to the public simply as Bedem, is the prominent symbol of Nikšić and a valuable fragment of the cultural and historical heritage of Montenegro. In the past decade the fortress has been renovated several times, aiming to emphasize the value and importance of the old ramparts, as well as to evaluate the spectrum of possibilities of its adaptation in the context of contemporary public city space. These interventions breathed new life into the dilapidated debris, implying its transformation from a warrior fortification into a reclaimed cultural and artistic center of the city. However, this idea never fully flourished, and the current condition of the city fortress is far from imagined- neglected, crumbled and devastated. With the exception of regional music festival “Bedem fest”, a and a few minor manifestations that have only scratched the surface of its enormous potential occasionally in the past decade, there are almost no other active initiatives and this monumental space remains the silent neglected urban pocket in the heart of the city. Although still dominant and crucial in the visual perception of Nikšić, the fortress today represents essential ravaged resource of the city. The purpose of this master thesis is to restore, conserve, reconstruct and repurpose the city fortress by creating an attractive destination inside as well as the outside of the walls, which would be enjoyed by both residents and tourists. The project aims to research the potential and discover the strategy model to restore new life and impose purpose to the rapidly devastating ramparts. The renewal paradigm is researched in the course of three main segments: adaptation, revitalization and repurpose. The project aspires to preserve the existing visual identity of the city walls and raise awareness of rich cultural and historical heritage trough introducing several museums, culture facilities as well as multicultural public spaces, resulting in a prominent landmark of high visibility and the local acropolis in the revived rebranded city.

Differential evolution and large-scale optimization applications
Aleš Zamuda, scientific or documentary film, sound or video publication

Abstract: Differential Evolution (DE) is one of the most popular, high-performance optimization algorithms with variants that have been outperforming others for years. As a result, DE has grown to accommodate wide usage for a variety of disciplines across scientific fields. Differential Evolution and Large-Scale Optimization Applications presents a research-based overview and cross-disciplinary applications of optimization algorithms. Emphasizing applications of Differential Evolution (DE) across sectors and laying the foundation for further use of DE algorithms in real-world settings, this video is an essential resource for researchers, engineers, and graduate-level students. Topics Covered : Algorithms, Optimization, Parallel Differential Evolution, Performance Improvement, Stochastic Methods, Tree Model Reconstruction.
Keywords: differential Evolution, optimization, algorithms, stochastic methods, tree models, tree model reconstruction

Weak k-reconstruction of Cartesian products
Wilfried Imrich, Blaž Zmazek, Janez Žerovnik, 2003, original scientific article

Abstract: By Ulam's conjecture every finite graph ▫$G$▫ can be reconstructed from its deck of vertex deleted subgraphs. The conjecture is still open, but many special cases have been settled. In particular, one can reconstruct Cartesian products. We consider the case of ▫$k$▫-vertex deleted subgraphs of Cartesian products and prove that one can decide whether a graph ▫$H$▫ is a ▫$k$▫-vertex deleted subgraph of a Cartesian product ▫$G$▫ with at least ▫$k+1$▫ prime factors on at least ▫$k+1$▫ vertices each, and that ▫$H$▫ uniquely determines ▫$G$▫. This extends previous works of the authors and Sims. This paper also contains a counterexample to a conjecture of MacAvaney.

Reconstructing 3D curves with euclidean minimal spanning trees
Simon Kolmanič, Nikola Guid, 2006, original scientific article

Abstract: In this paper, we present a new efficient algorithm for reconstruction of nonintersecting 3D curves from a sufficiently den se sample. We use the Euclidean minimal spanning trees to identify line segments reconstructing curve shapes. To deal with more than one curve in a sample and to eliminate noisy data, we introduce chains of connected line segments. With the incremental growth based on heuristics, the chains contain finally curve shapes. The method is robust and fast for both 2D and 3D curves.

Weak k-reconstruction of Cartesian products graphs
Wilfried Imrich, Blaž Zmazek, Janez Žerovnik, 2001, published scientific conference contribution abstract

Abstract: Po Ulamovi domnevi je mogoče vsak končen graf ▫$G$▫ rekonstruirati iz množice vseh podgrafov ▫$G$▫ brez ene točke. Znano je, da je mogoče rekonstruirati kartezične produkte. Obravnavan je soroden problem, imenovan šibka rekonstrukcija. Dokazano je, da je mogoče odločiti, ali se da dani graf ▫$H$▫ dobiti iz nekega kartezičnega produkta ▫$g$▫ z odstranitvijo ▫$k$▫ točk, če privzamemo, da ima ▫$G$▫ vsaj ▫$k+1$▫ faktorjev s po ▫$k+1$▫ točkami. V tem rimeru ▫$H$▫ enolično določa ▫$G$▫. Dan je tudi protiprimer za MacAvaneyjevo domnevo.
