This paper describes a novel hierarchy algorithm for extracting bridges over water in optical images. To reduce the omission of bridges by searching the edge
we extract the river regions which the bridges are included in. Firstly
we segment the optical image to get the coarse water bodies using iterative threshold
eliminate the noise regions and add the missing regions based on k-means clustering with texture information and spatial coherence. Then
the blanks are connected based on shape features and candidate bridge regions are segmented from river regions. Finally
the bridges are verified by geometric information and the ubiety between bridges and river. The results show that this approach is efficient and effective for extracting bridges in satellite image from Google Earth and in aerial optical images acquired by unmanned aerial vehicle. 2011 IEEE.

This paper proposes an effective framework to boost the efficiency of covariance matching. In this framework
covariance matrices are used to match object in complex environment by fusing multiple features. Then
Genetic Algorithm (GA) is employed to improve the processing speed of covariance matching. To take advantage of the property of GA for the optimization in large search spaces to covariance matching
a fitness function is designed using the distances between the covariance matrices of model and candidate regions. Experimental results show that the proposed approach can improve the processing speed of covariance matching observably. The computing speed of the proposed method is at least 7 times than that of exhaustive searching. 2010 IEEE.

A new method of affine object recognition and affine parameters estimation is presented. For a real-time image and a group of templates
in addition
firstly
on the basis of correct recognition
we segment the object regions in them and compute their covariant matrices. Secondly
it can estimate affine parameters exactly
normalize the ellipse regions defined by covariant matrices to circle regions to get rotational invariants
and the estimated error is within 3%. 2008 IEEE.
and compute the similarity function value between rotational invariants of real-time image and every template respectively. Then compare the values with threshold set in advance
if more than one value is larger than threshold
take the corresponding templates as candidates
and compute affine matrix between real-time image and every candidate. Finally
transform the realtime image with every affine matrix and match the result with corresponding candidate by classical matching methods. Experimental results show that the presented method is robust to illumination
with low computational complexity
and it can realize recognition of different affine objects
