%X This paper proposes a digital watermarking algorithm for remote sensing image based on DFT and watermarking segmentation.At first,it normalizes the host remote sensing image and determines an invariant centroid,then selects a square area around the invariant centroid for watermark embedding.Next,it generates a pseudo-random sequence as digital watermarking,and divides it into two parts.And finally it applies DFT to the selected region and embeds watermark into DFT phase and amplitude components of the selec...
