Resumen
El objetivo de este trabajo fin de grado es desarrollar una serie técnicas de implementación de zoom en imágenes, aprovechando para ello las propiedades de la transformada seleccionada, la idea es utilizar los datos localizados en las altas frecuencias de la transformada (que son todos aquellos valores que quedan en la periferia), para obtener el zoom. A tal fin se diseñará una aplicación, mediante el lenguaje de programación Matlab, que permita mostrar el funcionamiento de cada una de las técnicas, pudiendo el usuario aplicarlas de forma independiente, o bien en bloque siguiendo el orden que se desee. En este sentido, hay técnicas que funcionan de manera más eficiente, según el valor de zoom a realizar y el orden en el que se aplican a la imagen.
The objective of this final degree project is to develop a series of techniques for implementing zoom in images, taking advantage of the properties of the selected transform. The idea is to use the data located at the high frequencies of the transform (which are all those values that remain on the periphery) to obtain the zoom. To this end, an application will be designed using the Matlab programming language to demonstrate the operation of each of the techniques. The user can apply them independently or in bulk in any desired order. In this sense, some techniques work more efficiently depending on the zoom value to be applied and the order in which they are applied to the image.
