| Abstract: | According to the statistical characteristic of remote sensing image data, this paper introduces reversible integer-to-integer wavelet transforms into the field of remote sensing image coding by selecting SPIHT as image coding in this scheme. SPIHT is an algorithm, which is provided for image coding according to the inherent characteristic of the transformed coefficients. In the context of remote sensing image coding, some reversible integer-to-integer wavelet transforms and JPEG2000 are compared on the basis of their lossless compression rate. The experimental results show that all lossless compression rates of the proposed scheme are more excellent than that of JPEG2000. |
