Feature matching, which refers to finding the correct correspondences from two sets of features, is an important step in feature-based image registration. In this letter, an accurate and highly robust point-matching algorithm, which is called the integrated spatial structure constraint, is proposed. We establish a set of tentative correspondences using the scale-invariant feature transform algorithm...
In order to create a rapid, easy, and circulatory capabilities for multipurpose applications of remote sensing image, a network-oriented satellite remote sensing circulation architecture was proposed, and its key components was discussed in the same time. The client scheming and block data disposure were supplements to the integrity circulation architecture, conforming to which, clients can distribute...
Information on monthly and yearly SO2 and NO2 vertical column density means over the Yangtze River Delta from January 2005 to November 2010 was reported based the remote sensing data from the OMI sensor. In conclusion, from spatial perspective, the yearly SO2 average mean is high along the Nanjing-Shanghai railway line. And the further it is from the railway line, the less average mean is. The distribution...
Observations of tropospheric column densities of NO2 obtained from the satellite instruments OMI for the period of 2005 to 2010 are used to derive average monthly and seasonal variations over China. The obtained results indicate that NO2 has an imbalanced spatial distribution with the highest level in North China, Yangtze Rive Delta region and Pearl River Delta region. The seasonal pattern of the...
With the rapid growth of requirements on satellite remote sensing image data, effective management and efficient publication of increasingly large image data has become an urgent problem. Based on the features of massive image data and Web publication, this paper does a deep research and a thorough discussion on multi-resolution pyramid model of global satellite remote sensing images, gives a reasonable...
