With millions exported worldwide, it has invaded numerous countries, posing threats to native ecosystems due to its aggressive behaviour and competition. Recent observations in India indicate its presence in natural habitats, raising concerns. In February 2024, a live red-eared slider was discovered near the Sunderban Biosphere Reserve, marking the first known instance in an estuarine environment, highlighting its adaptability. While its effects are well-documented in many countries, research on this issue in India is somewhat limited. Native turtle species, particularly those in the Gangetic basin, face threats from various factors, including the growing ornamental pet trade, which worsens the situation due to consumer ignorance.

The aim is to address the limitations of conventional identification methods, which are known for their unreliability, inaccuracy, and susceptibility to manipulation, while also promoting the concept of intelligent livestock management. The ear images of pigs were obtained from a certified farm, processed according to established protocols, and subjected to feature extraction to create templates for subsequent matching within the same class and across different classes using various distance metrics such as Euclidean, Manhattan, Minkowski, and Hamming distances. Specifically, the points of branching in the vein pattern were utilized as features for template creation. By carefully analyzing each distance metric, a threshold level was established, with the average distance set at 20 for Manhattan distance and 40 for Minkowski, Euclidean, and Hamming distances, respectively. If the calculated matching distance falls below the threshold, the pig is successfully identified; otherwise, it is considered a different individual. The Euclidean distance metric demonstrated the highest accuracy in identification among all four metrics in the conducted experiments. A total of 54 pigs were included in the study, revealing that the “AEIN” technology achieved a remarkable accuracy rate of 98.18% when employing the Euclidean distance metric.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"48 3","pages":"343 - 349"},"PeriodicalIF":1.3,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145166722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
