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 ...
Domínguez Jiménez, María Elena(Universitat Politècnica de València, 2011-06-05)
[EN] In this work we emphasize the relationship between two -apparently very different- disciplines: digital photography and mathematics. In fact, digital images -that everybody handles nowadays- are mathematically modeled ...

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 ...

[ES] Se estudia la viabilidad del uso de autoencoders en la compresión de imágenes para escenarios de la vida real usando un método de división por cuadrícula de la imagen
original. Se construyen varios modelos, utilizando ...
