We present a computationally efficient color image fusion algorithm for merging infrared and visible images. At the core of the proposed method is the color transfer technique based on the linear YCBCR space. The method directly uses the grayscale fused image and the difference signals of the input images to construct the source YCBCR components
then uses the statistical color transfer technique to form a color fused image that takes the target image's color characteristics. Two different strategies
which respectively employ the pixel averaging fusion scheme and the multiresolution fusion scheme as the grayscale image fusion solution
are proposed to fulfill different user needs. The simple strategy using the pixel averaging fusion scheme answers to a need of easy implementation and speed of use. And the complex strategy using the multiresolution fusion scheme answers to the high quality need of the fused products. In addition
we also describe some useful theories about color-transfer-based image fusion. Experimental results show that the proposed color image fusion algorithm can effectively produce a natural appearing "daytime-like" color fused image
and even using the pixel averaging fusion scheme to implement the grayscale fusion can also provide a pleasing result. 2010 Copyright SPIE - The International Society for Optical Engineering.

Hough transform is recognized as a powerful tool in shape analysis which gives good results even in the presence of noise and the disconnection of edge. However
3. applying the standard Hough transform equation to every point of the input image edge
4. according to the local threshold
6. merging the segments whose extreme points are near. Experiment results show the approach not only can recognize regular geometric object but also can extract the segment feature of real targets in complex environment. So the proposed method can be used in the target detection of complicated scenes
traditional Hough transform can only detect the lines
2. quantizing the parameter space
and extracting a group of maximums according to the global threshold
eliminating spurious peaks which are caused by the spreading effects
and will improve the precision of tracking.
cannot give the endpoints and length of the line segments and it is vulnerable to the quantization errors. Based on the analysis of its limitations
Hough transform has been improved in order to detect line segment feature of targets. The algorithm aims to avoid the loss of spatial information
as well as to eliminate the spurious peaks and fix on the line segments endpoints accurately
5. fixing on the endpoints of the segments according to the dynamic clustering rule
which can expediently be used for the description and classification of regular objects. The method consists of 6 steps: 1. setting up the image
parameter and line-segment spaces
