Mobility implies a great variability of capturing conditions, which is not easy to control and directly affects face detection the extraction facial features. Deep learning solutions seem be most interesting choice for automatic recognition, but they are highly dependent on model generated during training stage. In addition, size models makes it difficult their integration into applications oriented mobile devices, particularly when must embedded. this work, small-size deep-learning was...
Palm vein recognition has emerged as a novelty highly invariant biometric technique that is difficult to forge due their internal nature. In this work the texture descriptors Local Binary Patterns (LBP) and Uniform (LBPU) are analyzed feature extraction methods for verification based on palm veins. Their performance efficiency been studied through multivariate analysis including impact of different wavelengths parameters descriptor number neighboors radio. CASIA Multi-Spectral Palmprint...
Single sample per person verification has received considerable attention because of its relevance in security, surveillance and border crossing applications. Nowadays, e-voting bank the future solutions also join this scenario, opening field research to mobile low resources devices. These scenarios are characterised by availability a single image during enrolment users into system, so they require solution able extract knowledge from previous experiences similar environments. In study, two...
Biometrics is an active research field that increasingly being integrated into current technology. As a result, more and people are becoming familiar with biometric technics such as fingerprint or facial recognition. Nevertheless, there innovative techniques ear-based biometrics which not very well known yet because they at initial stages of research. In this work, ear geometry-based verification system oriented to recognition through mobile phones presented evaluated. Feature extraction...
Comfort and security perception are two key factorsto provide an adequate biometric solution. This article presentsthe results of online survey about these characteristics in fourdifferent modes implemented mobile phones withwidespread sensors. Additionally, it presents the main concernsthat use generates people, whichprovides a roadmap additional issues that should be improvedto create satisfactory techniques.
Segmentation is a crucial stage in hand biometric recognition due to its direct influence on the feature extraction process. The actual trend toward contactless biometrics adds new challenges traditional defiances, which are mainly related capturing conditions and limitations computational resources. Traditional methods do not succeed when variable imposed able deal with daily-life situations are, general, computationally expensive. In this study, competitive flooding-based segmentation...
This work presents a configurable multibiometricsystem oriented to mobile devices which combines face, handand in-air signature biometrics provide three different levelsof security. The number of traits involved in the authenticationincreases with security strength, allowing balance betweencomfort and accuracy according requirements ofthe final application. In addition, system isenhanced by incorporating anti-coercion aliveness detectionmechanisms. To decide biometric mode should be...
Lung cancer is the leading cause of death. More than 238,340 new cases lung patients are expected in 2023, with an estimation more 127,070 deaths. Choosing correct treatment important element to enhance probability survival and improve patient's quality life. Cancer treatments might provoke secondary effects. These toxicities different health problems that impact Hence, reducing while maintaining or improving their effectiveness goal aims be pursued from clinical perspective. On other hand,...
In this work, the Curvelet transform is proposed as a fairly new feature extraction method for palmprint recognition. Particularly, multiscale analysis has been performed at four levels, assessing and combining features extracted each level in order to find those which better represent palmprint. Feature matching conducted by means of Euclidean distance Support Vector Machines (SVMs), comparative results are provided. addition, multimodal approach involving hand geometry also evaluated,...
Interest on palmprint biometrics has experimented a strong growth in the last decades due to its useful characteristics as uniqueness, permanence, reliability, user-friendliness, acceptability, non-intrusiveness, and low cost of acquisition devices, which make it attractive for civil commercial applications. Accordingly, wide research been developed this field. Nevertheless, there is lack evaluation results under common framework permits obtain fair comparison between different methods. In...
Lung cancer is the leading cause of death. More than 236,740 new cases lung patients are expected in 2022, with an estimation more 130,180 deaths. Improving survival rates or patient's quality life partially covered by a common element: treatments. Cancer treatments well known for toxic outcomes and secondary effects on patients. These toxicities different health problems that impact life. Reducing without decline positive effect important goal aims to be pursued from clinical perspective....
Lung cancer is the leading cause of death. From estimation cases that will be in 2021, more than 230,000 new are expected to lung patients, with an 131,000 deaths. Improving survival rates or patient's quality life partially covered by a common element: treatments. Collective knowledge about treatment recommendations typically included clinical guidelines, intended optimize patient care and assist clinicians treatment. These guidelines define set paths, where depend on disease aspects...
