Abstract

This paper presents a vector filtering framework for color image zooming. Popular vector filters such as the vector median filter, the basic vector directional filter and the data-adaptive vector filter are used to enlarge the spatial resolution of the full-color, red-green-blue images. Extensive experimentation reported in this paper indicates that the proposed color image zoomers preserve the spectral and spatial characteristics of the processed image and produce enlarged images without color shifts and artifacts.
