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.

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.
