The banks based on the intellectual capital efficiency index showed that only 40% are within the successful category and that human capital efficiency was more influential in generating value.

The fused images were evaluated both in spatial and spectral quality through four indices, specifically: correlation index, ERGAS, RASE and Q index, in order to determine the efficiency of the proposed methods. Best results of the spectral evaluation were obtained with the MULTITWA image, achieving correlations higher than 0.95, a Q index of 0.96 and a RASE value of 9.2%, while spatially higher values than 0.96.

The scenarios are emulated using development software called Unity. Silhouettes are virtualized images of typical targets useful to improve familiarity with the environment, precision and dexterity required by a shooter. The evaluation and qualification of the accuracy of the shot has as its main element a camera similar to a webcam, and under a total darkness environment, it is capable of evaluating with high precision the place of the silhouette where the infrared laser beam hit. The laser is adapted to a firearm through mechanical and electronic components. The image is processed using color recognition, edge detection, center of mass, and point detection; information that allows discriminating the contour of the laser and its center, to then assign a numerical value to the shot made. This ability to evaluate homographic images is another important contribution of this research. The results obtained in this investigation, after having made more than 10,000 shots, show the validity and significant contribution of the proposed system. The metrics presented are the product of actual shooting training exercises with people with little experience in the field.","PeriodicalId":187896,"journal":{"name":"2022 17th Iberian Conference on Information Systems and Technologies (CISTI)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114905206","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}
