Abstract:Passive crowd counting using channel state information (CSI) is a promising technology for applications in fields such as smart cities and commerce. However, the most existing algorithms can only recognize the total number of people in the monitoring area and cannot simultaneously recognize the number and states of people and ignore the real-time performance of the algorithms. Therefore, they cannot be applied to the scenarios of multi-state crowd counting requiring high real-time performance. To address this … Show more
The paper focuses on introducing 2D texture analysis as a quantitative method for functional analysis in archaeology. Indeed, for the first time, different techniques of quantitative feature extraction and machine learning algorithms applied to the functional analysis of archaeological lithic tools are described and compared. The method presented relies on five techniques of quantitative feature extraction from photographic images and six classification techniques through machine learning algorithms. After creating a training dataset with experimental traces, machine learning models were used to classify 23 images (10 experimental and 13 archaeological). The best result achieved a classification accuracy of 87%, demonstrating the ability to interpret use-wear traces correctly on both experimental and archaeological artefacts regardless of the geological origin of the flint (Sicily in Italy and Sachsen-Anhalt in Germany). The paper proposes to use the method as a fundamental tool in functional analysis to remove subjectivity criteria from traditional analysis and to address issues related to the credibility of the discipline, calibration, standardisation, and reproducibility of methods and results.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
