This paper proposes a novel approach to face recognition using string of minimum values (SMV) as a new face feature extractor for face representation. Unlike most of the face representative methods, which focus only on micro-structures information in image analysis, by surrounding the treated pixel with a mask. The proposed descriptor uses the chains of unit vectors in four directions, by moving from the current pixel to the next one, from which to a new next pixel, and so on, in order to encode also the global appearance of the face image. Furthermore, seven distance metrics from the nearest neighbour classifier are evaluated in the classification stage. The experimental results show which metrics perform well and demonstrate the efficiency of the proposed approach in terms of recognition rate compared to the existing face recognition methods.

This paper proposes the usage of traceability data to enhance the continuous evaluation and monitoring of quality. The current study focuses on processing activities where it is difficult to detect and evaluate the possible degradation of quality. It has indeed a special interest in possible gaps that are not bridged by existing quality methods and practices, especially tasks that involve significant physical contact with manual labour. Therefore, this research introduces a computer-aided system that combines ontology-based knowledge with a fuzzy-based decision-making process. The proposed model can ensure the main traceability functions, including identifying, tracing, and tracking. Also, it can handle the various attributes associated with processing activities to assess the possible loss of quality. In case of unconformity, this monitoring function enables decision-makers to intervene appropriately. The developed system has also been illustrated through a fish canning case study.

This paper consists of an introduction, section, and a conclusion. In the introduction, we review some fundamental arithmetic proprieties of finite local rings R2, which will be used in the remainder of this article. The section is devoted to the study the above mentioned twisted Hessian curves on these finite local rings for restriction to some specific characteristic p ≥ 5. Using these studies, we give essential properties and we define the group H2a,d, these properties, the classification of these elements and a bijection between the sets H2a,d and Ha0,d0 × 𝔽q, where Ha0,d0 is the twisted Hessian curve over the finite field 𝔽q.Keywordstwisted Hessian curves, finite over ring, cryptography, elliptic curves, local ring Previous article Next article FiguresReferencesRelatedDetails Volume 18Issue 1-32023 ISSN: 1757-2657eISSN: 1757-2665 HistoryPublished onlineNovember 28, 2022 Copyright © 2023 Inderscience Enterprises Ltd.Keywordstwisted Hessian curvesfinite over ringcryptographyelliptic curveslocal ringAuthors and AffiliationsAbdelâli Grini1 Abdelhakim Chillali2 Lhoussain El Fadil3 Hakima Mouanis4 1.
