The present application relates to
remote sensing information processing technical field, for solving the problem of low
algorithm accuracy of existing hyperspectral classification method, poor auxiliary
training effect of source domain
data set and so on, and proposes a kind of
small sample hyperspectral classification method based on cross-domain spectral band alignment, comprising: S1, reading the source domain
data set D source And target domain
data set D target Of hyperspectral data set, calculate the aligned spectral
wavelength range and the aligned band number N align ;S2, by parabolic interpolation and
resampling alignment method, the spectral
wavelength range and band number N align Of two data sets are unified;S3, select training sample, collect training support set and training query set to construct
small sample learning task S4,
train embedding network F emb Determine
network model parameters;S5, collect test support set and
test query set from target domain data set, determine the predicted class
label of each sample using nearest
neighbor algorithm, and then complete the classification of
small sample hyperspectral.
