In the hyperspectral data, the phenomenon of stripe deletion often occurs, which seriously affects the efficiency and accuracy of data analysis and application. Narrow band deletion can be directly repaired by interpolation, and this method is not ideal for wide band deletion repair. In this paper, an adaptive spectral wide band missing restoration method based on panchromatic information is proposed, and the effectiveness of the algorithm is verified by experiments.
It is very difficult to monitor the pollution and diffusion of nuclear facilities directly by remote sensing image. This paper proposes a method of nuclear pollution detection using the wide band hyperspectral data, the vegetation health status as the intermediate variables, the indirect detection of nuclear power plant pollution, and the feasibility of this method are discussed.
This paper presents a novel method to describe the contour in the complex background, features are extracted object contour partial occlusion or lack of conditions, and effectively detect the image features. The validity and robustness of the proposed method is proved by the experiment of remote sensing image.
The space-based information moving target detection method is mainly based on the traditional SAR/GMTI implementation, but at present our country still does not have to orbit satellite SAR/GMTI. This paper presents a minimal time difference with multi spectral image channel method for moving target detection, the multispectral image channel cannot imaging flaws to the clever use, moving object detection and velocity estimation.
It is very difficult to detect a moving object then estimate its speed with optical remote sensing images. In this paper, we propose a novel method that moving object detection and velocity measurement using only single multispectral image. Slight chromatic aberration among channels of the multispectral image is applied to detect the motional object by fames difference, and improve the accuracy of velocity measurement using pixel unmixing. Finally, experiments are carried out on satellite multispectral images from Google Earth and clearly show the comparative effectiveness of the proposed method with respect to traditional methods.
