watermark-11187
作为一种新型的有效的版权保护手段，数字水印技术倍受人们的关注。数字水印主要是通过在原始资料中嵌入秘密信息——水印,来证实资料的所有权。本文介绍了数字水印技术的基本原理及其分类，然后对数字水印讨论了一种基于LSB的数字图像水印算法,最后利用MATLAB7.6对这一算法进行了实现。(As a new effective means of copyright protection, digital watermarking technology much attention. The digital watermark secret information- the watermark embedded in the raw data, to prove ownership of the data. This article describes the basic principles of their classification of digital watermarking technology and digital watermarking digital image watermarking algorithm based LSB, and finally the use of this algorithm matlab7.6 achieve.)

Ship-detection
复杂杂波背景下，海面红外图像中舰船目标检测的关键是如何降低虚警、检测出真正的
目标。为了实现这个目标，首先利用Haar小波函数进行小波变换，对图像进行预处理；然后进行恒
虚警检测（CFAR）；第三步采用行程法对检测的目标进行标记；最后采用管道滤波法剔出虚假目标，
检测出真正的目标。经仿真实验证明，此方法能有效地降低虚警，在复杂杂波背景中检测出目标。
(The key of ship detection in sea infrared image with complex clutter background is how to
reduce false alarms and detect true targets.In order to achieve this aim,a novel algorithm is proposed.
First,Haar wavelet transform technology is used as preprocessing,then constant false alarm rate(CFAR)
detetion,then run-length label to mark objects detected by the above step,finally pipeline filter to reduce
false alarms and detect true targets.Experiment results indicate that this method can effectively reduce false alarms and detect true targets in complicated sea background.
