Multiple definitions and concepts have been developed throughout various fields, which demand consolidation and reorganisation. Heritage buildings are complex assets, yet the need for their preservation is undeniable. The safeguarding of such resources may benefit from the advantages DT offer, nevertheless the relation between both subjects could use further exploring. This work consisted in the development of an evaluation methodology named Heritage Digital Twin (HDT), composed by four attributes determined by the relation between DT and built heritage, which also demanded a brief revision of the concepts and primary elements of the DT concept, as well as previous DT evaluation frameworks. Three Portuguese case studies were used to exemplify the application of the methodology at different scales (in size, relevance and DT complexity). The application examples proved the methodology is able to provide an easy and effortless HDT assessment, allowing a simple yet meaningful indication of the development of each attribute. Heritage-related actions are still limited following the virtual-to-physical communication, in contrast with operative actions, which causes HDT to rely on human intercession. The framework successfully considered built heritage limitations, providing an inclusive approach. Nonetheless, the constant advancements in technology might change the perspective for HDT in the future.</div></div>","PeriodicalId":38225,"journal":{"name":"Digital Applications in Archaeology and Cultural Heritage","volume":"36 ","pages":"Article e00390"},"PeriodicalIF":0.0,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142720206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To test the performance of the proposed method, a total of 110 low-resolution samples of Kannada stone inscription images were collected from internet sources for the experimental setup due to the non-availability of the standard datasets for the Kannada stone inscriptions. The collected data set samples from the internet were complex in nature to read the contents present on stone images. The experimental workflow of the proposed method is to separate the text and non-text regions from the stone inscription images using a proposed technique for setting the coordinates. Then, the preprocessing process starts to filter out the noises and other unwanted regions found in the image foreground region using the median filtering composition method. Finally, the hybrid approach is implemented using a Fuzzy adaptive thresholding technique for the elimination of the background region of the input image and smooth enhancement of Kannada stone inscription images due to enormous challenges related to perspective distortion, diverse lighting conditions, the minimal disparity between the foreground and background, a lack of standardized text size and shape, reduced perceptible colour contrast, and associated noises. Hence, we obtained an enhancement accuracy of 78.18% using a hybrid method. The obtained accuracy is more acceptable compared to existing methods found in the global literature and is also carried out during the experimental study. The novelty of the paper is working on low-resolution ancient Kannada stone inscription images and a hybrid approach to enhance the quality of the original input image.</div></div>","PeriodicalId":38225,"journal":{"name":"Digital Applications in Archaeology and Cultural Heritage","volume":"35 ","pages":"Article e00385"},"PeriodicalIF":0.0,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142586905","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 loss of material in these components and changes in their cross-section geometry significantly impact the stability and load-bearing capacity of historic buildings. A portable LiDAR device is utilized to acquire the cross-section geometry of the deteriorated components. The irregular cross-section profiles are extracted using point cloud slicing and the Alpha-Shape algorithm. Geometric characteristics such as cross-section area, moment of inertia, and moment of resistance are calculated using Green's integral method. The performance of this method is evaluated by measuring eight groups of deteriorated components with different cross-section characteristics and comparing it with five traditional methods. The results demonstrate that the proposed method improves the calculation accuracy by 1%–21% relative to traditional methods, thereby enhancing reliability by 9%–54%. Additionally, it reduces manual calculation workload and human error, while promoting calculation efficiency. The method exhibits excellent applicability and high efficiency, with an error below 3% when compared to the true value. This method proves valuable in evaluating the extent of deterioration in historic timber components and provides essential data for preventive conservation and restoration of historic timber buildings.</div></div>","PeriodicalId":38225,"journal":{"name":"Digital Applications in Archaeology and Cultural Heritage","volume":"35 ","pages":"Article e00384"},"PeriodicalIF":0.0,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142593034","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}

Preserving the aesthetic and cognitive values inherent in traditional styles poses a significant challenge compared to other tangible assets. However, the digitization of built heritage offers a proactive approach to conservation. In this regard, the management of heritage building information through Building Information Modeling (BIM) plays a crucial role in preventive conservation. The utilization of multi-dimensional digital information models, known as Historic Building Information Modeling (HBIM), is one such approach. This study aims to explore the application of HBIM in representing built heritage, focusing specifically on the research gap pertaining to the need for an effective and integrated methodology for modeling information related to heritage urban facades. The objective is to generate parametric models within the framework of HBIM information management, thereby contributing to preventive preservation mechanisms. The methodology employed in this study consists of two main parts. Firstly, information is derived by analyzing the structural characteristics of heritage facades using Shape Grammar. Secondly, the acquired information is utilized to develop a comprehensive library of HBIM for heritage architectural elements. The results of this study demonstrate the proposed methodology's effectiveness in determining heritage urban facades' morphological, mathematical, relational, and Euclidean characteristics.</div></div>","PeriodicalId":38225,"journal":{"name":"Digital Applications in Archaeology and Cultural Heritage","volume":"35 ","pages":"Article e00383"},"PeriodicalIF":0.0,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142420436","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}
