level transformation to preprocess image. We will also explain how the double win-
dow binarization, erosion, suspected target extraction and dilation are used to remove
useless image information in order to eventually extract the suspected target. This
method can be used to help photographic interpreter for further interpretation.
The experimental results show that the method can achieve rapid and effective ex-
traction through the remote sensing image which has complex background and objects
area with homogeneous gray value. The missing rate tends to zero. The implementa-
tion of target extraction, the internal of which is non-uniform, represents the content
of further study.
