This paper presents a change detection approach for high-resolution remote sensing image combined the pre-classification with the post-classification comparison. Firstly, a spectrum correction image is constructed on the basis of fusing the differential and ratio algorithm, which can alleviate the effects of single band's sensitivity. Secondly, a binary change mask is extracted from the spectrum correction...
The full name of HJ satellite is environment and disaster monitoring and prediction small satellite constellation. Currently two satellites of HJ satellites have been put into use. This paper will first introduce the present situation about fog detection using remote sensing technology. Then the spectral characteristics, geometric characteristics, time characteristic of HJ satellite will be analyzed...
In this paper, we firstly introduced the MODIS L1B data and preprocess of MODIS L1B data, and then analyzed the two steps of preprocess: ldquoradiometric calibrationrdquo and ldquoprojection transformrdquo in detail, finally we used three different strategies to parallelize the process of MODIS L1B data of ldquoradiometric calibrationrdquo and ldquoprojection transformrdquo. The result of the experiment...
A new algorithm for removing Bowtie effect of Moderate resolution Imaging Spectrometer (MODIS) data without utilizing the ephemeris data is proposed in this paper. Based on a thoroughly study of the observation characteristics of MODIS, and a comprehensive comparison and evaluation among the existing algorithms for removing Bowtie effect, the new algorithm is derived with correlation coefficient method...
