  • Exponential family Fisher vector for image classification 

    Sánchez, Jorge; Redolfi, Javier (2015-07-01)
    One of the fundamental problems in image classification is to devise models that allow us to relate the images to higher-level semantic concepts in an efficient and reliable way. A widely used approach consists on extracting ...

  • Fisher vectors for leaf image classification: an experimental evaluation 

    Redolfi, Javier; Sánchez, Jorge; Pucheta, Julián (Springer, Cham, 2015-10-25)
    In this work we present an experimental evaluation of the exponential family Fisher vector (eFV) encoding applied to the problem of visual plant identification. We evaluate the performance of this model together with a ...

  • Fisher Vectors for PolSAR Image Classification 

    Redolfi, Javier; Sánchez, Jorge; Flesia, Ana Georgina (SADIO, 2018-09)
    In this letter, we study the application of the Fisher vector (FV) to the problem of pixelwise supervised classification of polarimetric synthetic aperture radar images. This is a challenging problem since information in ...

  • Identificación de hojas de plantas usando Vectores de Fisher 

    Redolfi, Javier; Sánchez, Jorge; Pucheta, Julián (SADIO, 2015-08)
    En este trabajo se propone el uso de descriptores locales codificados con el método de Vectores de Fisher para resolver el problema de clasificación de hojas de plantas usando imágenes. Se demuestra que con este enfoque ...
