The development of modern science and technique has given more challenge to image processing, so science researchers have to seek for other new methods of image processing. But with traditional math transformation methods, some questions can’t be solved such as receiving high compression ratio and shorting compression time. So we consider that it may be [...]

Geo-Correction of High-Resolution Satellite Imagery and Its Accuracy Measurement
Posted by GIS PARK on April 9th, 2011
Dealing with various spatial information, the extraction of spatial information from High-Resolution Satellite Imagery(HRSI) is a hot topic of Digital Photogrammetry, GIS and other fields. Aiming at the linear CCD push-broom of high resolution satellite imagery, theory and application on imagery geometry correction is discussed in the paper. The main work are as follows,1. Because [...]
Research on Microwave Radiometer Characterization Testing System
Posted by GIS PARK on April 9th, 2011
In this dissertation, general research situation of both domestic and international microwave radiometer calibration and characterization testing technologies are introduced. Deep theoretical analyses are carried on several key questions like radiation characteristic of calibration load, near-field pattern of horn antenna and so on. Calculations are done on the base of analysis. Detailed and intuitionistic results [...]
Remote Sensing Image Fusion Based on Multiwavelet Transform
Posted by GIS PARK on April 9th, 2011
With the development of modern remote sensing technology, more and more multi-resolution, multi-temporal and multi-spectral remote sensing image data are provided by different kinds of remote sensors. But these remote sensing image data are not same in the different fields because of observation limit and dissimilar design of the remote sensors. To get a more [...]
Quantitative Relationship between Multi-Angle Polarized Reflectance and BRDF
Posted by GIS PARK on April 9th, 2011
When using remote sensing data to increase the discernment capability of the Earthsurface, angle information was found to have influence and contribution to the identity andclassification of object in remote sensing images. In fact, the full angle information of anobject is its three-dimensional spectrum characteristics in 2π space. Two approaches havebeen used to characterize the [...]
