基于小波变换的红外图像海天线检测算法研究

摘要在海空复杂背景中如何去除海杂波以及云层的影响，快速的检测、识别红外小目标是红外图像处理邻域中的难题。在海面远距离平视的状态下，红外图像一般分为三个区域：海面区域、天空区域和海天线区域。远方小目标多存在于海天线附近的区域中。针对上述特点，通过精确确定海天线区域，可以大幅减少执行目标分割时的计算量，还可以抑制海天线区域外不必要的噪声干扰。因此海天线的检测在海空背景下的目标检测中具有重要的意义。27673

Title: Research on sea-sky line detection in infrared image based on Wavelet Transform
Abstract
How to remove the sea clutter and the effect of clouds in the complicated background of sea and sky, rapid detection, identification infrared small targets in infrared image processing is a big challenge. In the offing remote horizontally state, the infrared imagines are generally pided into three areas: sea area，sky-area and the sea-sky area. The distance small target exists in the sea-sky line area. In view of the above features, by determining the sea-sky line area, it can reduce the computational quantity of the target segmentation, while restraining the unnecessary noise from the sea-sky line area. So it has important significance in the target detection under the sea sky background.
In the first chapter, the research background and the research status of the wavelet theory are briefly introduced; In the second chapter, the basic principle of wavelet analysis is briefly introduced; In the third chapter, there is brief introduction of sea-sky line detection algorithm. In the fourth chapter, the MATLAB software is briefly introduced, and the simulation experiment is carried out by MATLAB, and the results are finally obtained. Other algorithms related advantages and disadvantages; combined with the effect of sea sky line detection in background of sea and sky infrared image to compare the pros and cons of algorithm and other algorithms wavelet decomposition. Analysis the algorithm of detection results and characteristics.
Keywords: Sea and sky background, Sea sky line detection, Wavelet analysis, MATLAB simulation
