In its introductory part, it theoretically describes applied biometrics and biometric systems for security identification and user verification, and also deals with the theory of the description of algorithms for human face detection and recognition. Subsequently, the authors use the MATLAB programming language, which is highly optimized for modern processors and memory architectures, to focus on the implementation and testing of a biometric system using Viola-Jones algorithms and a convolutional neural network with a pre-trained network NetNet. Convolutional neural networks (CNN) are the most recognized and popular deep-learning neural networks, which are based on layers that perform two-dimensional (2D) convolution of input data with learned filters. In the final part there is a discussion where, based on the results of testing, the robustness and efficiency of the proposed intelligent biometric system is objectively evaluated. The results allow for the continued development of other pre-trained artificial neural networks, variable implementations for facial recognition, but also other things, such as the recognition of potentially dangerous people.","PeriodicalId":375880,"journal":{"name":"22nd SGEM International Multidisciplinary Scientific GeoConference Proceedings 2022, Informatics, Geoinformatics and Remote Sensing","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125062358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dimitrov","doi":"10.5593/sgem2022/2.1/s09.21","DOIUrl":"https://doi.org/10.5593/sgem2022/2.1/s09.21","url":null,"abstract":"The article summarizes the main geodetic activities performed in the region of Southwestern Bulgaria to study the modern crustal movements and clarify the geodynamic situation of the region. The study area is bounded to the north of the southern slopes of the Balkan Mountains, to the south to the southern slopes of the Rila Mountains, to the west � the western border of Bulgaria and to the east � the beginning of the Upper Thracian plain. The area has a complex geological structure with many active faults that must be studied. The region is of particular interest due to its high population density and high concentration of industrial facilities and resources. The main geodetic method for studying the crustal movements are GPS measurements, their processing and analysis of the results. To study the modern crustal movements in 1996- 1997, a geodynamic network was built that cover Southwestern Bulgaria. The network is designed for precision GPS measurements, determination the velocities of points and calculation of active strain. The results for velocities and strain rates of longtime monitoring are given. The velocities of the points are between 1.5mm/y of the northern most station and slightly over 3mm in the southern most station. The obtained result for strain rate field shows dominating N-S extension and the deformation is not uniformly distributed over the area. The strain rate field result confirms that the movement of points in the region of southwestern Bulgaria is in a southerly direction relative to stable Eurasia. This extensive movement of southern Bulgaria and northern Greece is also confirmed. Due to the long period of measurements the results are highly reliable and can be used for detailed geodynamic and geological study of the active fault structures in the region.","PeriodicalId":375880,"journal":{"name":"22nd SGEM International Multidisciplinary Scientific GeoConference Proceedings 2022, Informatics, Geoinformatics and Remote Sensing","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128615515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"THE POTENTIAL OF BIOCHAR AND COMPOST MIXTURE TO INCREASE THE MAIZE CANOPY DURING THE VEGETATIVE SEASON","authors":"Elena Aydın","doi":"10.5593/sgem2022/2.1/s10.43","DOIUrl":"https://doi.org/10.5593/sgem2022/2.1/s10.43","url":null,"abstract":"Biochar is being studied for few decades as it finds various applications in mitigating climate change, improving soil properties and water retention which subsequently potentially improves the crop yields. One of the parameters potentially predicting the crop yield is the crop density during the vegetation period as it represents the number of plants per area unit that can photosynthesize and potentially bring yield at the end of vegetation season. The paper presents the observations on the changes in canopy density during the vegetative part of the vegetation season of maize (Zea mays L.) which was estimated using non-destructive method of close canopy imagery. The field observations were done at the experimental site in Dolna Malanta near Nitra (Slovakia). In 2014, a commercially purchased soil additive (biochar mixed with compost � BC) was applied to plots (4 x 6 m of size) of agricultural land in the rates of 0, 10 and 20 t/ha. The application rates of BC were combined with 3 levels of NPK fertilizer application (0, 160 and 240 kg N/ha). During the observation period from mid-May 2015 up to beginning of July 2015, images of maize canopy parallel to soil surface were taken from above the crop canopy with camera built up in the mobile. The canopy density was evaluated using the Breedpix software. The canopy density three weeks after sowing ranged from 1.7 to 2.1 % at the control treatments (without BC) at different fertilization levels. The values at treatments with BC ranged from 2.1 up to 2.4 and from 1.9 up to 2.6 % at the application rate 10 and 20 t/ha, respectively. Although in general higher values were observed at treatments with BC application, the differences were not significant. The canopy density over the studied period increased in all treatments, at the end of June the values ranged from 39 to 40 % at the treatments without BC and from 39 to 46 % at treatments with BC at 10 t/ha and from 38 up to 58 % at the treatments with BC at 20 t/ha application rate. Although majority of differences were not statistically significant, it can be concluded that overall biochar mixed with compost slightly increased the density of the maize canopy at least in the early stages of the development. As the maize height was increasing, the sampling method was not suitable as it was not possible to take image of the full canopy within the row. For such applications it might be useful to take photos from larger height preferably with UAV.","PeriodicalId":375880,"journal":{"name":"22nd SGEM International Multidisciplinary Scientific GeoConference Proceedings 2022, Informatics, Geoinformatics and Remote Sensing","volume":"24 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132938808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our research is focused on imaging brain structures in neurology. In this paper we present differences of digital image analysis of the substantia nigra (SN) between US and MRI using the same algorithm. In the past, we developed an application for analyzing substantia nigra echogenicity in BMODE US images. Our developed application is based on a principle of binary thresholding in Region of Interest (ROI) to evaluate echogenicity grade. Increased echogenicity of SN is one of important markers for Parkinson�s Disease (PD) progress. The goal of this paper is to analyze if the same principle used for US B-MODE imaging is also applicable for different MR sequences to find out SN changes. From the achieved results detectable SN changes using MRI are possible at least as a complementary examination to US imaging. We need to prove if echogenicity index (called Echo-Index) is well reproducible value between two different MR sequences; SWI and T2-TSE; how to distinguish between pathological SN and normal anatomy. In the first pilot analysis, it seems that the principle of Echo-Index measurement could be a starting point to create a new large clinical study in this field. Totally 23 MR images from two different sequences (T1 and T2) were analyzed in this pilot study. However, it seems that Echo-Index cannot distinguish normal and diseased SN.","PeriodicalId":375880,"journal":{"name":"22nd SGEM International Multidisciplinary Scientific GeoConference Proceedings 2022, Informatics, Geoinformatics and Remote Sensing","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127863675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper presents the present-day field activity of bathymetric research, which revised available hydrographic data for the seabed. The study aims to combine and update archival bathymetric data from contemporary multibeam echo-sounding scanning and archive single-beam data. This work presents activity in the second stage of Project �Multidisciplinary study of Burgas Bay � MidBay. (Composition of a detailed digital model of the bottom relief with analysis of modern geomorphological conditions and archaeological forecasting modelling)� with a primary scientific goal to create an overall bathymetric model of the Burgas and Pomorie bays. The studied bay is strongly anthropogenically modified by the port in its southern part. The reconstruction of seafloor topography will allow the detection of substrate varieties and the identification of contemporary geomorphological bedforms and processes. A historical review of hydrographic research and geo base database was created for the seabed of the Bulgarian coastal zone in support of this study with different-year bathymetric surveys. The used data consolidate sonar mosaics, single beam, multibeam bathymetric data and raster satellite images, processed in PDS 2000, SonarWiz, and GIS environment. The coverage and density of the bathymetric data allowed the generation of a seabed digital bathymetric model with a horizontal resolution of 11 m. In addition, a bathymetric map with an interval of 0.5 m was created with high accuracy. Such a high-resolution model is an important advance in the highresolution mapping of the Bulgarian Black Sea coastal zone.","PeriodicalId":375880,"journal":{"name":"22nd SGEM International Multidisciplinary Scientific GeoConference Proceedings 2022, Informatics, Geoinformatics and Remote Sensing","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134394361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies have found a relationship between Phenocam data and above-ground dry biomass. In this context we investigate the modeling of barley fresh above and underground biomass with Green chromatic coordinate (Gcc) colour index, extracted from Phenocam data, and multi-output Gaussian processes (MOGP). We take advantage of the available very high temporal resolution data from the phenocam to predict the biomass. The MOGP models take into account the relationships among output variables learning a cross-domain kernel function able to transfer information between time series.
