dcthide
dct隐写技术matlab实现资料。算法原理:通过在一个图像块中调整两个DCT系数的相对大小,隐藏秘密信息。
将载体图像分为8×8的块,做二维DCT变换
用来表示选中的两个系数的坐标对于第i bit秘密信息
if(要隐藏信息‘1’)

逆DCT变换,还原图像
(dct steganography matlab implementation information. Algorithm principle: an image block by adjusting the relative size of the two DCT coefficients, hidden secret information. The vector image is divided into 88 blocks, making two-dimensional DCT transform coefficients used to represent the coordinates of the selected two for the first i bit secret information if (to hide information ' 1 ' ) make else make the inverse DCT, restore image)

Energy-Efficient-Cooperative-Image-Transmission-(
We compare the energy efficiency of some transmission
schemes in wireless sensor networks. By constraining
the system to end-to-end throughput requirements, we assume
that the nodes in multi-hop and cooperative schemes operate
at a spectral efficiency which is twice that of the single-hop
transmission. By taking into account the energy consumption of
the RF circuitry, we show that cooperation may be considerably
more energy efficient than non-cooperative schemes even in small
transmission ranges, specially if a feedback channel is available.
