Images compression is a widely studied topic. Conventional situations offer variable compression ratios depending on the image in question and, in general, do not yield good results for images that are rich in tones. Thi...

The discriminative model learning for image denoising has been recently attracting considerable attentions due to its favorable denoising performance. In this paper, we take one step forward by investigating the construc...

We propose a natural scene statistic-based distortion-generic blind/no-reference (NR) image quality assessment (IQA) model that operates in the spatial domain. The new model, dubbed blind/referenceless image spatial qual...

Las técnicas de multiresolución permiten, con un primer conjunto reducido de datos, disponer de una versión aproximada de cierta imagen a transferir. Con el agregado de sucesivos detalles, puede completarse dicha imag...

Multiwavelets are new addition to the body of wavelet theory. There are many types of symmetric multiwavelets such as Geronimo-Hardin-Massopust (GHM) and Chui-Lian (CL) multiwavelets. However, the matrix filter generatin...

Este trabalho descreve a avaliação, através de curvas “recall x precision”, de um conjunto de técnicas para recuperação de imagens baseadas nos conteúdos cromático e estrutural das mesmas. Durante a aplicaç...

En particular nos interesa la automatización de procesos de reconocimiento y clasificación de objetos que provienen de una línea industrial (de producción o packaging). Lo cual trae consigo la incorporación de compu...

Las últimas décadas de desarrollo tecnológico se caracterizaron por una creciente necesidad de integrar conocimientos multi e interdisciplinarios, contrariando el paradigma reduccionista que había caracterizado a la ...

In this paper we present two basic modules whithin the designed scheme for retrieving images of a database from the object colour and shape in the scenes. On the one hand, we desing a new method to detect edges in colour...

Depth estimation from monocular images can be retrieved from the perspective distortion. One major e ect of this distortion is that a set of parallel lines in the real world converges into a single point in the image pla...

Este trabajo tuvo lugar en el marco de un proyecto de colaboración entre el LIDI (Laboratorio de Investigación y Desarrollo en Informática) del Departamento de Informática preteneciente a la Facultad de Ciencias Exac...
