  • 2-D Continuous Wavelet transform for ESPI phase-maps denoising 
    Escalante, Nivia; Villa Hernández, José de Jesús; De la Rosa Vargas, José Ismael; De la Rosa Miranda, Enrique; González Ramírez, Efrén; Gutiérrez, Osvaldo; Olvera Olvera, Carlos Alberto; Araiza Esquivel, María Auxiliadora (Elsevier, 2013-04)
    In thiswork we introduce a 2-D Continuous Wavelet Transform (2D CWT) method for denoising ESPI phase-maps. Multiresolution analysis with 2-D wavelets can provide high directional sensitivity and high anisotropy which are ...
  • A 2-D Continuos Wavelet Transform method for InSAR phase-maps Denoising 
    Escalante, Nivia; Villa Hernández, José de Jesús; De la Rosa Vargas, José Ismael; Olvera Olvera, Carlos Alberto; Alaniz Lumbreras, Daniel; Gutiérrez, Osvaldo (SPIE, 2013-07)
    Analysis of Interferometric Synthetic Aperture Radar (InSAR) phase–maps with large wide band is still a challenging problem that requires the development of robust methods. This paper presents a 2–D Continuous Wavelet ...
  • Algoritmo para desenvolvimiento de fase unidimensional partiendo de un interferograma con frecuencia portadora implementado en labview 
    Cardona Valdez, Juan Carlos; Pinedo Vargas, Miguel Eduardo; Arceo Olague, José Guadalupe; Saucedo Anaya, Tonatiuh; De la Rosa Vargas, José Ismael; Olvera Olvera, Carlos Alberto (Instituto Tecnológico de Chihuahua, 2016-10)
    En el análisis de interferogramas, el desenvolvimiento de fase es una tarea primordial ya que al calcular la fase, ésta resulta estar envuelta en un mapa con un rango entre -π a π o bien, de 0 a 2π. Al contar con un mapa ...
  • An alternative method for phase-unwrapping of interferometric data 
    De la Rosa Miranda, Enrique; González Ramírez, Efrén; Villa Hernández, José de Jesús; Berriel Valdos, Luis Raúl; Olvera Olvera, Carlos Alberto; De la Rosa Vargas, José Ismael; Saucedo Anaya, Tonatiuh; Arceo Olague, José Guadalupe (European Optical Society, 2014-09)
    In this paper we present a novel algorithm for phase unwrapping where only a subset of data from the wrapped phase map is used to reconstruct the unwrapped phase map as a linear combination of radial basis functions (RBF’s). ...
  • Desarrollo de un Sistema para estimación de Evapotranspiración por la Técnica de Surface Renewal 
    Espinosa García, Gustavo; Olvera Olvera, Carlos Alberto; De la Rosa Vargas, José Ismael (Universidad Nacional Autónoma de México, 2014-10)
    La técnica de Surface Renewal fue usada para estimar la densidad del flujo de calor sensible (H), para lograr dicha estimación fue necesario realizar mediciones de temperatura a una frecuencia de 10 Hz, esto para analizar ...
  • Efficient numerical analysis of optical imaging data: A comparative study 
    Duarte Correa, David; Pastrana Palma, Alberto; Olvera Olvera, Carlos Alberto; Ramírez Rodríguez, Sergio; Alaniz Lumbreras, Daniel; Gómez Meléndez, Domingo; De la Rosa Vargas, José Ismael; Noriega, Salvador; Torres, Vianey; Castaño, Víctor (Elsevier, 2013-11)
    The computational efficiency of 14 optical detectors over six types of transformations, namely: blur, illumination, rotation, viewpoint, zoom, and zoom-rotation changes, was analyzed. Images with the same resolution (750×500 ...
  • Estimation of the temperature of flame with asymmetric profile 
    González Ramírez, Efrén; Berriel Valdos, Luis Raúl; Arceo Olague, José Guadalupe; De la Rosa Miranda, Enrique; Olvera Olvera, Carlos Alberto; Saucedo Anaya, Tonatiuh; De la Rosa Vargas, José Ismael; Villa Hernández, José de Jesús (SPIE, 2014-03)
    The large number of projections needed for tomographic reconstruction makes prohibitive the use of algebraic methods for fast phase object reconstruction. However, for smooth and continuous phase objects, the reconstruction ...
  • Phase unwrapping using a surface mesh with constraints 
    Arceo Olague, José Guadalupe; Berriel Valdos, Luis Raúl; De la Rosa Miranda, Enrique; González Ramírez, Efrén; Olvera Olvera, Carlos Alberto; Saucedo Anaya, Tonatiuh; Villa Hernández, José de Jesús; De la Rosa Vargas, José Ismael (SPIE, 2014-03)
    Phase unwrapping is an intermediate step for interferogram analysis. A smooth phase associated with an interferogram can be estimated using a curve mesh of functions. Each of these functions can be approximated by a linear ...
  • Semi-Huber Half Quadratic Function and Comparative Study of Some MRFs for Bayesian Image Restoration 
    De la Rosa Vargas, José Ismael; Villa Hernández, José de Jesús; González Ramírez, Efrén; De la Rosa Miranda, Enrique; Gutiérrez, Osvaldo; Olvera Olvera, Carlos Alberto; Castañeda Miranda, Rodrígo; Fleury, Gilles (European Optical SocietySpringer, 2013-10)
    The present work introduces an alternative method to deal with digital image restoration into a Bayesian framework, particularly, the use of a new half-quadratic function is proposed which performance is satisfactory ...
