    • Regularized spectral log difference technique for ultrasonic attenuation imaging 

      Coila Pacompia, Andres Leonel (Pontificia Universidad Católica del Perú, 2017-07-13)
      The attenuation coefficient slope (ACS) has the potential to be used for tissue characterization and as a diagnostic ultrasound tool, hence complementing B-mode images. The ACS can be valuable for estimation of other ...
    • Robust Minimmun Variance Beamformer using Phase Aberration Correction Methods 

      Chau Loo Kung, Gustavo Ramón (Pontificia Universidad Católica del Perú, 2017-04-28)
      The minimum variance (MV) beamformer is an adaptive beamforming method that has the potential to enhance the resolution and contrast of ultrasound images. Although the sensitivity of the MV beamformer to steering vector ...
    • Separable dictionary learning for convolutional sparse coding via split updates 

      Quesada Pacora, Jorge Gerardo (Pontificia Universidad Católica del Perú, 2019-05-16)
      The increasing ubiquity of Convolutional Sparse Representation techniques for several image processing tasks (such as object recognition and classification, as well as image denoising) has recently sparked interest in ...
