KEY WORDS: Speckle Noise, SAR Speckle Reduction, Filtering Techniques.
ABSTRACT:
The speckle noise appearing in SAR images forms a main obstacle to analyse, interpret and classify SAR images for
various remote sensing applications. To date, many filters have been developed for speckle reduction in SAR
imagery. In this paper, the authers evaluate eight ready-made speckle filters, which are Moving Average Filter,
Median Filter, Lee Filter, Enhanced Lee Filter, Frost Filter, Enhanced Frost Filter, Kuan Filter and Gamma MAP
Filter, in order to test these filters with ERS-1&2 data and provide a guideline for users are interested in SAR
applications. The evaluation has been done from three aspects, which are statistical model testing, quantitative
evaluation and qualitative evaluation. The test results presented in this paper confirm that filtering techniques are
helpful for SAR image applications.
1. Introduction
The earliest concept of speckle is introduced from the
laser field[1], which indicated that the interference of
the coherent and dephased reflected scatters will cause
a peculiar granular pattern in the image due to the
majority of surfaces being extremely rough on the scale
of the wavelength. This concept is suitable to SAR
speckle as the SAR system has a similar principal with
the laser imaging system. Therefore, the SAR speckle is
related with laser speckle both physically and
mathematically so that the large amount of material on
laser speckle is applicable to understand the
phenomenon of SAR speckle.
For several decades, many mathematical models of
SAR speckle noise have been deeply investigated
[2][3], which took the speckle noise as a kind of
multiplicative noise. By using the statistical properties
of the SAR image, the probability density function(pdf)
of a normalized multiplicative fading process can be
expressed as an exponential pdf, which provide the
fundamental theory for SAR speckle reduction
techniques. Many speckle filtering techniques based on
the speckle model of multiplicative noise are well
developed.
In solution to the incoherence of SLAR systems, which
are relatively immured to speckle due to performing an
incoherent summation of N independent estimation of
the radar backscatters with the same resolvable
element, the multi-look algorithm[4] has been proposed
to reduce the speckle noise. It is realized in the
frequency domain by segmentation of the azimuth
164
spectrum to form several independent single-look
images and summation of these images to obtain a
multi-look images. The drawback is that the speckle
reduction is accompanied by loss of image resolution.
The second category technique to reduce speckle noise
is referred to the time domain algorithm, as it performs
speckle filtering after a full resolution is processed. It
has advantages over the conventional frequency domain
multi-look technique due to the fact that it is much
easier to compromise the balance between the image
resolution and speckle reduction, and more flexible to
filter the full resolution images with the different filters.
Many speckle filters are well developed, such as Box
Filter[4], Median Filter[5], Lee Filter[6], Enhanced Lee
Filter[10], Frost Filter[8], Wiener Filter[11], Kuan
Filter[11], GMAP[9], Geometric Filter[13] and so on.
The main goal of these speckle filters is to reduce
speckle noise to a minimum, in order to achieve image
quality as good as photography does. However, these
filters still cannot meet the requirement of the purposes
of easy interpretation and clear classification. The
reason is that the properties of SAR speckle are more
complicated to be modeled as an exponential
distribution. In some cases, the statistical model
violates this distribution. The different terrain and
different SAR systems, for example, terrain size, terrain
geometry, moisture, dielectric constant, wavelength,
polarization, view angle and so on, will generate the
different speckle noises. How to overcome it with one
filter has become a difficult and long-term task that has
been treated by many scientists. In spite of these
deficiencies discussed above, the majority of image
processing software packages have been formed
