This paper presents a novel framework based on image
processing techniques for the radio environment characterisation.
Specifically, after digitalising a given scenario in accordance with
the frequencies that are detected in each point, an image can be
built whose pixel intensities capture the radio-electrical
conditions. Through non-linear filtering and object detection
operations the proposed framework allows identifying the
homogeneous regions where certain frequencies can be detected.
This methodology can be used in different contexts, such as the
construction of databases to provide the terminals with spectrum
awareness in flexible spectrum scenarios to facilitate the switch-on
procedure or the secondary usage of spectrum, the support to
devise proper strategies for cell and RAT selection, etc.
