In the field of remote sensing imaging
TDICCD remote sensing images have a lot of their own characteristics
such as high-resolution
large amount of information
less overlapping parts of pixels
additional image blurring etc. Therefore
there exist many difficulties
especially in terms of high-accuracy registration of pairs of images. For that
this paper presents two new pixel interpolation method for sub-pixel level registering images that allows for scaling
translation and rotation. The proposed technique
which is based on the maximization of the correlation coefficient function
combines an efficient pixel-moving interpolation scheme with surface fitting
which greatly reduces the overall computational cost. The accuracy of the algorithm is evaluated by calculating correlation coefficient of couples of points belonging to images transformed with preset factors and also comparing it to other sorts of methods. The experiment results show that the accuracy of registration reaches 0.01 pixels. 2010 IEEE.
