This paper proposed a sub-pixel image correlation algorithm that can get more Precise result
its principle is apply the distribute of relativity peak to get weighted multi-pixel comprehensive of location. Image correlation be as to calculates the greyscale relativity of image template and matching image
the relativity of correspond location where match best with template will be most high
and in its neighbour range
the relativity will be still keep high too. We used these pixel in this local area of calculated match point to get sub-pixel accuracy
the relativity of every pixel be used as its weight for participate the sub-pixel calculation. The sub-pixel location is more accuracy than the integer one
we applied this method to perform background compensation in processing the target detecting for video image sequence. At the end of this paper
some experiment data be proposed
it proved this sub-pixel image correlation can obtain better result. 2011 SPIE.

The fundamental goal of target recognition and video tracking is to match target template with source image. Most matching methods are based on image intensity or multi-feature points. And the latter method is more popular for its high accuracy and small calculation. Image Registration Based on Feature Points focus on effective feature extraction of image points and paradigm. Harris corner in the image rotation
gray
noise and viewpoint change conditions
has an ideal match results
is more recent application of one feature point. This paper extract the Harris corner deviation and covariance firstly
experiments show that the two features exclusive
then applied them to image registration for the first time. A set of actual images have shown
this proposed method not only overcomes the complicated background
gray uneven distribution problems
but also pan and zoom the image has a good resistance. 2011 IEEE.

In order to meet requirement of real-time and high accuracy in image matching aided navigation
SSDA algorithm is used to match remote sensing image and template image coarsely
a fast and effective algorithm of remote sensing image matching based on corner detection is put forward. With the combination of rough and fine match
when the matching result is bigger than one to count absolute value sum of energy difference of characteristic point energy to realize fine match of remote sensing image and template image to locate the position of template image in remote sensing image accurately. Simulation experiment proves that the matching of a remote sensing image resolution of 1018*1530 and a template image resolution of 150*90 can be fulfilled within 2.392 second
wavelet transform is used to acquire low frequency component to realize image compression to decrease calculation work and increase matching speed. Harris corner detection algorithm is used to detect corner of remote sensing image and template image and energy of every corner is calculated
the algorithm is robust and effective
real time image navigation can be achieved. 2009 SPIE.
