5 - Analyse spectrale locale de l'image par transformation de Wigner-Ville
1992
Local spectrum analysis is an interesting method to extract
pertinent features of an image . This paper proposes a new
local spectrum analysis method allowing to accurately
characterize the local spatial frequency content of an
image. It is based on the use of the two-dimensional
Wigner-Ville distribution (2D WVD), which permits to
separately control spatial and frequential analysis resolutions.
The application of this method to texture feature extraction and discrimination is illustrated, and a comparison
with the classical 2D spectrogram method is also
given.
