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.

Automatic target detection is very difficult in complicate background of sea and sky because of the clutter caused by waves and clouds nearby the sea-level line. In this paper
in view of the low-flying target near the sea is always above the sea-level line
we can first locate the sea-level line
and neglect the image data beneath the sea-level line. Thus the noise under the sea-level line can be suppressed
and the executive time of target segmentation is also much reduced. A new method is proposed
which first uses neighborhood averaging method to suppress background and enhance targets so as to increase SNR
and then uses the multi-point multi-layer vertical Sobel operator combined with linear least squares fitting to locate the sea-level line
lastly uses the centroid tracking algorithm to detect and track the target. In the experiment
high frame rate and high-resolution digital CCD camera and high performance DSP are applied. Experimental results show that this method can efficiently locate the sea-level line on various conditions of lower contrast
and eliminate the negative impact of the clutter caused by waves and clouds
and capture and track target real-timely and accurately.
