In recent years, GIS (Geographic Information System) develops rapidly, and it is applied in various industries. But the application of GIS in telecommunication information resources(such as Base Station) management is far behind its application in other areas. Using the programmable interfaces provided by Google Earth API, we created an information management system which has the map functions to...

This paper proposes a watermarking embedding and extracting methods in the frequency domain based on a selection of a high frequency range containing large amount of information. The selected high-frequency range contributes to the imperceptibility of the watermark while the robustness against compression is achieved because the selected frequency range contains large amount of information. The entropy-based...
In this paper, an algorithm based on wavelet-based contourlet transform is proposed for remote sensing image fusion. This method mainly involves three steps: The first stage provides subband decomposition, which in the case of the WBCT is a wavelet transform, in contrast to the Laplacian pyramid used in contourlets. The second stage of the WBCT is a directional filter bank (DFB), decomposition of...

JPEG2000 is the image compression standard which includes three core techniques: wavelet lifting scheme and EBCOT and MQ arithmetic coder. The EBCOT algorithm uses a Wavelet transform to generate the subband samples, which are quantized and coded. Normal Wavelet transforms fail to represent such functions effectively while Ridge functions are effective in representing functions that have discontinuities...
