    A General Model for the Design of Efficient Sign-Coding Tools for Wavelet-Based Encoders 
    López-Granado, Otoniel Mario; Martínez-Rach, Miguel Onofre; Martí-Campoy, Antonio; Cruz-Chávez, Marco Antonio; Pérez Malumbres, Manuel (MDPI AG, 2020-11)
    [EN] Traditionally, it has been assumed that the compression of the sign of wavelet coefficients is not worth the effort because they form a zero-mean process. However, several image encoders such as JPEG 2000 include ...

    Applying a Genetic Algorithm Solution to Improve Compression of Wavelet Coefficient Sign 
    Martí-Campoy, Antonio; López, Otoniel; Rodríguez-Ballester, Francisco; Perez Malumbres, Manuel Jose (Springer, 2015-06-10)
    Discrete Wavelet Transform has been widely used in image compression because it is able to compact frequency and spatial localization of image energy into a small fraction of coefficients. In recent years coefficient sign ...

    Improving image compression through the use of evolutionary computing algorithms 
    López-Granado, O; Galiano, V; Martí Campoy, Antonio; Migallón, H.; Martinez Rach, Miguel Onofre; Piñol, Pablo; Perez Malumbres, Manuel Jose (Witpress, 2013)
    Discrete Wavelet Transform has proved to be powerful for image compression because it is able to compact frequency and spatial localization of image energy into a small fraction of coefficients. For a long time it was ...

    Monitoring pest insect traps by means of low-power image sensor technologies 
    López ., Otoniel; Martinez Rach, Miguel Onofre; Migallon ., Héctor; Perez Malumbres, Manuel Jose; Bonastre Pina, Alberto Miguel; Serrano Martín, Juan José (MDPI, 2012-11-13)
    Monitoring pest insect populations is currently a key issue in agriculture and forestry protection. At the farm level, human operators typically must perform periodical surveys of the traps disseminated through the field. ...

    On the design of a bioacoustic sensor for the early detection of the red palm weevil 
    Martinez Rach, Miguel Onofre; Migallón, Héctor; López Granado, Otoniel; Perez Malumbres, Manuel Jose; Martí Campoy, Antonio; Serrano Martín, Juan José (MDPI, 2013-01)
    During the last two decades Red Palm Weevil (RPW, Rynchophorus Ferrugineus) has become one of the most dangerous threats to palm trees in many parts of the World. Its early detection is difficult, since palm trees do not ...

    On the design of fast and efficient wavelet image coders with reduced memory usage 
    Oliver Gil, José Salvador (Universitat Politècnica de València, 2008-05-06)
    Image compression is of great importance in multimedia systems and applications because it drastically reduces bandwidth requirements for transmission and memory requirements for storage. Although earlier standards for ...
