Image Edge Detection Using Fractional Calculus with Feature and Contrast Enhancement
Amita Nandal,Hamurabi Gamboa-Rosales,Arvind Dhaka,José M. Celaya-Padilla,Jorge I. Galván-Tejada,Carlos E. Galván-Tejada,Francisco J. Martinez-Ruiz,Cesar H. Guzmán-Valdivia +7 more
TL;DR: By theoretical and experimental results, it is observed that the proposed feature and contrast enhancement of image using Riemann–Liouville fractional differential operator outperforms the existing methods under comparison.
Journal ArticleDOI
Multi-factor authentication model based on multipurpose speech watermarking and online speaker recognition
Mohammad Ali Nematollahi,Hamurabi Gamboa-Rosales,Francisco J. Martinez-Ruiz,José Ismael De la Rosa-Vargas,Syed Abdul Rahman Al-Haddad,Mansour Esmaeilpour +5 more
TL;DR: The developed MFA model is able to enhance the security of the systems against spoofing and communication attacks while improving the recognition performance via solving problems and overcoming limitations.
Journal ArticleDOI
Contralateral asymmetry for breast cancer detection: A CADx approach
José M. Celaya-Padilla,Cesar H. Guzmán-Valdivia,Carlos E. Galván-Tejada,Jorge I. Galván-Tejada,Hamurabi Gamboa-Rosales,Idalia Garza-Veloz,Margarita L Martinez-Fierro,Miguel A Cid-Baez,Antonio Martinez-Torteya,Francisco J. Martinez-Ruiz,Huizilopoztli Luna-García,Arturo Moreno-Baez,Amita Nandal +12 more
TL;DR: The proposed method has the potential to rank subjects by their probability of having breast cancer, aiding in the re-scheduling of the radiologists’ image queue, an issue of utmost importance in developing countries.
Journal ArticleDOI
Digital Speech Watermarking Based on Linear Predictive Analysis and Singular Value Decomposition
Mohammad Ali Nematollahi,Chalee Vorakulpipat,Hamurabi Gamboa-Rosales,Francisco J. Martinez-Ruiz,José Ismael De la Rosa-Vargas +4 more
TL;DR: In this article, a digital speech watermarking technique is proposed by applying both Linear Predictive Analysis (LPA) and SVD Quantization Index Modulation (QIM) to embed the watermark bits.
Book ChapterDOI
Understanding Peripheral Audiences: From Subtle to Full Body Gestures
TL;DR: A spectrum of full body gestures is analyzed to understand the reaction of the Peripheral audience and it is shown that interactive users are more likely to be stressed if these interactions are performed in the presence of an audience.
