Abstract
The method for improving remote sensing image spatial resolution is the target of the top research scientists in the field of remote sensing. Up to now, the way to improve image spatial resolution by upgrading and manufacture of new advanced sensors that allow taking high spatial resolution images has enormous costs. In addition, spectral resolution was often limited while enhanced spatial resolution. These reasons prompted scientists to discover the method for improving spatial resolution by transformed algorithms to high resolution images based on received images. This article focuses on assessing some super-resolution methods which develop so far. The result will be scientific basis for the purpose of enhancing resolution to better use of VNREDSat-1 data.
