Image matching has been one of the most fundamental issues computer vision over the decades. In this paper we propose a novel method based on making use of feature lines in order to achieve more robust image matching. The feature lines have the properties of rotation and scaling invariance
coined RIFLT(Rotation invariant feature line transform). Experimental results demonstrate the effectiveness and efficiency of the proposed method. Compare with the famous powerful algorithm Scale Invariant Feature Transform(SIFT)
the proposed method is more insensitive to noise. And for certain sequence of images
which contain clear lines
the proposed method is more efficiency. Using the feature lines obtained by our method
it is possible to matching two scene images with different rotation angles
scale and light distort. 2011 IEEE.

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.

Scene matching under complex background is a priority and difficulty in the field of computer vision
it has the characteristics of rotation and scaling invariance
commonly used in matching real-time collected images and photos for navigation. Scene matching techniques are faced with complex natural scenes
anti-light and anti-slight-distortion
the image distortion exist
applicable for complex scene matching. The project has a new idea: combining the keylines with the vectors description based on polar image translation
such as light
and utilize the rotation-scale-invariance vectors to describe the extracted keylines
change of gray levels
this method includes three steps: keylines extraction
perspective
description and matching. Preliminary experiments show that this keylines-based scene matching algorithm is applicable for image matching under complex background. 2010 IEEE.

It is difficult to choose eigenvectors when neural network recognizes object. It is possible that the different object eigenvectors is similar or the same object eigenvectors is different under scaling
shifting
rotation if eigenvectors can not be chosen appropriately. In order to solve this problem
the image is edged
the membership function is reconstructed and a new threshold segmentation method based on fuzzy theory is proposed to get the binary image. Moment invariant of binary image is extracted and normalized. Some time moment invariant is too small to calculate effectively so logarithm of moment invariant is taken as input eigenvectors of BP network. The experimental results demonstrate that the proposed approach could recognize the object effectively
correctly and quickly.
