A new transformation technique for reducing information entropy : a case study on greyscale raster images
Borut Žalik, Damjan Strnad, David Podgorelec, Ivana Kolingerová, Luka Lukač, Niko Lukač, Simon Kolmanič, Krista Rizman Žalik, Štefan Kohek, 2023, izvirni znanstveni članek

Opis: This paper proposes a new string transformation technique called Move with Interleaving (MwI). Four possible ways of rearranging 2D raster images into 1D sequences of values are applied, including scan-line, left-right, strip-based, and Hilbert arrangements. Experiments on 32 benchmark greyscale raster images of various resolutions demonstrated that the proposed transformation reduces information entropy to a similar extent as the combination of the Burrows–Wheeler transform followed by the Move-To-Front or the Inversion Frequencies. The proposed transformation MwI yields the best result among all the considered transformations when the Hilbert arrangement is applied.

Reflection symmetry detection in earth observation data
David Podgorelec, Luka Lukač, Borut Žalik, 2023, izvirni znanstveni članek

Opis: The paper presents a new algorithm for reflection symmetry detection, which is specialized to detect maximal symmetric patterns in an Earth observation (EO) dataset. First, we stress the particularities that make symmetry detection in EO data different from detection in other geometric sets. The EO data acquisition cannot provide exact pairs of symmetric elements and, therefore, the approximate symmetry must be addressed, which is accomplished by voxelization. Besides this, the EO data symmetric patterns in the top view usually contain the most useful information for further processing and, thus, it suffices to detect symmetries with vertical symmetry planes. The algorithm first extracts the so-called interesting voxels and then finds symmetric pairs of line segments, separately for each horizontal voxel slice. The results with the same symmetry plane are then merged, first in individual slices and then through all the slices. The detected maximal symmetric patterns represent the so-called partial symmetries, which can be further processed to identify global and local symmetries. LiDAR datasets of six urban and natural attractions in Slovenia of different scales and in different voxel resolutions were analyzed in this paper, demonstrating high detection speed and quality of solutions.

Aplikacija koncepta digitalnega dvojčka v športu : diplomsko delo
Luka Lukač, 2022, diplomsko delo

Opis: V diplomskem delu predstavljamo aplikacijo koncepta digitalnega dvojčka pri športnih treningih, s čimer omogočimo izvajanje treningov brez fizične prisotnosti osebnega trenerja. Vmesnik med športnikom in digitalnim dvojčkom predstavlja naprava AST-Monitor, ki teče na mobilnem računalniku Raspberry Pi in s senzorji zajema metrike napora treninga ter jih posreduje digitalnemu dvojčku. Digitalni dvojček med intervalnim treningom spremlja športnikov napredek, s pomočjo algoritmov strojnega učenja analizira prejete podatke in športniku v realnem času svetuje, kaj storiti v danem trenutku.
Ključne besede: digitalni dvojček, šport, trening, AST-Monitor
