In order to improve the speed of matching algorithm and simplify the processing of existing sub-block coding matching
a new template matching method combined local gray value encoding matching and phase correlation is proposed. Matching process is divided into rough matching and fine matching. Rough matching divides the image into certain size blocks called R-block
sums the gray value of each R-block pixel
encodes the R-block according to the gray value distribution of R-block with the adjacent R-block
and matches by step between the template and each search sub-image. Then
fine matching results are obtained using phase correlation according to initial match parameters. The time complexity of the proposed method is (M2) .The new algorithm is faster than traditional algorithm by two orders of magnitude
and the speed has improved twice compared with existing sub-block coding method. Experiments demonstrate that the new algorithm is robust to the linear transformation of pixel grey value and image noise
and it also has the stability of small-angle rotation. 2009 IEEE.

The trace of star trail is an important component of deep sky detection. The stars are low contrast targets
and their self-rotation will make their brightness change in cycle. Above all
the trail trace is vulnerable to the block and disturbance of other stars. Traditional one-dimensional maximum entropy thresholding algorithm is vulnerable to the noise
and the calculation of two-dimensional entropy methods is too large and takes too much time. This paper proposes an improved two-dimensional entropy threshold algorithm. We use recursion iteration method to eliminate the redundancy calculation
and reduce the size of two-dimensional histogram based on the deep sky stars characteristic
such as low contrast
fuzziness and the centralized histogram. We also combine our algorithm with the space trail trace model to forecast the star trace. Experiments results show
when the star are blocked or they turn dark
the method still can well extrapolate the star trace. Our method improves the capability of trailing the ebb and small star
and increases the precision of tracing. It is also robust to the noise
so there is a good application foreground for the method.
