高分遥感成像系统MTF对土地利用图斑 边界提取的影响
Effects of the modulation transfer function of high spatial resolution remote sensing imaging system on boundary extraction in land use patches
摘要
Abstract
In order to confirm the rules of the modulation trancter function(MTF)of the high spatial resolution remote sensing imaging system to the boundary extraction in land use patches,by changing the MTF value of the high spatial resolution remote sensing imaging system,and determining the errors of the boundary extraction in land use patches with the OBIA approach,the function relationships between the MTF values and the errors of the boundary extraction in land use patches were established.Experimental results show that the errors of the boundary extraction in land use patches are less than 1％ as the MTF values are greater than 0.35 and rapidly increase when the MTF values are less than 0.25.The MTF values and the corresponding errors of the boundary extraction in land use patches approximately obey the logarithmic relationships.Further analysis reveals that the larger the spectral separability between land use patches and patch size,the smaller the error of the boundary extraction in land use patches.关键词
