When trying to extract information from SAR images, we need to distinguish
two types of image property. The more important is where properties of the
scene (e.g., its dielectric constant, its geometry, its motion, etc.) produce effects
in the image measurements or examination of the image then can provide
information about the scene. The second is generated purely by the system
and the signal processing.
Abstract—The contourlet transform is a new two-dimensional
extension of the wavelet transform using multiscale and direc-
tional fi lter banks. The contourlet expansion is composed of
basis images oriented at various directions in multiple scales,
with fl exible aspect ratios. Given this rich set of basis images,
the contourlet transform effectively captures smooth contours
that are the dominant feature in natural images.

The bus communication system of EN1434-3 is commonly called M-Bus. Its application layer describes
a standard especially for meter readout. It can be used with various physical layers and with link layers
and network layers which support the transmission of variable length binary transparent telegrams.
