Clonal Selection Algorithm is one of the important artificial intelligence algorithms, which used as a powerful information processing and problem-solving paradigm in both the scientific and engineering fields. However, few studies concern application of CLONALG method in information extracting of satellite image. In this paper, we suggest modified Clonal Selection Algorithm (M-CLONALG) improved by niche technology's sharing function and memory calculator technique applying to remote sensing (RS) image information extracting. In order to testify the correctness that M-CLONALG improves the stab...
