    摘要： The present disclosure relates to an inter prediction method and apparatus using adjacent pixels, and a video encoding method and apparatus using the same. The inter prediction method for a predictive encoding includes: determining a current motion vector by estimating a motion of a current block; generating a reference block indicated by the current motion vector; calculating a motion compensation coefficient or an average compensation coefficient by using pixels neighboring the current block and pixels neighboring reference block; generating a changed reference block reflecting the motion compensation coefficient or the average compensation coefficient in the reference block; and determining the changed reference block as a predicted block of the current block. The present disclosure reduces a difference between an actual block and a predicted block by more accurately predicting the block to be encoded, thereby improving the compression efficiency.

    摘要： The present invention relates to a method that obtains emissivity or reflectivity based on ratios of the brightness temperature measured by a satellite and the land surface temperature, calculates two reflectivity using polarizing features of a microwave according to surface characteristics, and measures a volumetric soil water content of a land surface considering that water has different physical characteristics from those of soil. In particular, it may be possible to measure volumetric soil water contents on territories of other countries as well as regions which have many limitations and troubles in direct measurement of the volumetric soil water contents. Accordingly, valuable materials in terms of nation economy may be produced together with substantial contribution to industrial fields that have direct effects on agriculture and disaster prevention.
