Abstract:
This paper proposes a comparative study and
analysis in satellite image Registration. Image registration
techniques are aimed to improve the geometrical consistency of
satellite images. This technique can be employed for the
detection of changes in images .we are analyzing Point based,
Edge based and Contour based image registration techniques.
In the first method control points are selected manually and
registration is performed using cross correlation. Edge based
image registration emphasized on corner features. Two pairs
of optimal matching corners were selected from matched
corners as control points and transformation is applied. In
contour based approach contour points are extracted from
image and based on the contour points image registration is
performed .Finally localization error and matching error is
calculated and analyzed.
