Ship Target Detection Technology Multispectral Image

The ship detection is the current research hotspots, which has the extremely important application value. However, the accuracy and validity of the problems still exist about detection in practical work. In this paper, I want to do some exploration by Using wavelet fusion detection and color space transform fusion detection for the technology basing on satellite multispectral remote sensing image.In this paper, the principle of multispectral remote sensing image has been expounded firstly. And the current situation of application has been introduced, the characteristic of spatial resolution, spectral resolution, radiation resolution and time resolution have been also analyzed. Then the algorithm of multispectral remote sensing image fusion based on wavelet transform and color space conversion have been respectively contrasted and analyzed. Moreover, the experimental research of image fusion based on the multiple multispectral remote sensing image has been carried. And the performance results of the two algorithms of multispectral remote sensing image fusion have been also contrasted and analyzed. The results show, as the number of stages of wavelet transform is raised, the main features of ship are more obvious, which is propitious to detect object. And this research has established a theoretical basis for ship detection technology research in this paper.The ship detection technology based on multispectral remote sensing image has been researched in this paper. The detection method based on the principle of wavelet and color space fusion has been discussed. And the experimental research of multispectral remote sensing image of much sea area has been carried, which is used for analyzing the method effect for detecting the ship. The studies have shown, in the method of wavelet detection, the brightness of ship is much higher than that of sea area, and if the peak value is higher, the target characteristic is more obvious. Moreover, in the method of color space fusion, more characteristics of weak signal can be detected, and people can discover and judge the target more easily after color fusion. Therefore, the organic integration of the wavelet and color space detection method can detect more ships effectively, and the detection results are more accurate.
