Description: 电子稳像的实时鲁棒性算法，首先对采集到的每帧图像建立高斯金字塔。然后在高斯金字塔的顶层进行
初估计，采用图像块法得到整像素的运动估计矢量。精估计采用光流梯度法。为提高鲁棒性，运用简化的M 收敛法
进行梯度约束。最后阶段采用双线性内插对当前帧与参考帧进行匹准-Electronic image stabilization, real-time robust algorithm, first collected in the establishment of Gaussian pyramid for each frame. And then carry out the early top-level Gaussian pyramid is estimated to be using the whole-pixel image block method of motion estimation vector. Precision is estimated using optical flow gradient method. To improve robustness, the use of M-convergence method to simplify constraint gradient. The final stage of using a bilinear interpolation on the current frame and reference frame bolts of quasi-

Description: 随着遥感、GIS领域对高分辨率、大幅面卫星图像的需求越来越强烈，高分辨率、大幅面可见光卫星正在迅速增加，同时，其单幅卫星图像的幅面也在急剧扩大。一般的卫星遥感图像数据量往往大到以ＧＢ为单位。
我们考虑采用分块、索引及搭建图像金字塔的方式实现大幅面卫星影像的显示与漫游。打开影像不受机器及数据量大小的限制。。。这里把源程序提供给大家。
-With remote sensing, GIS in the field of the high-resolution, large format satellite images of the demand for more and more intense, high-resolution, large format visible satellite is rapidly increasing, while its format from single satellite images are also expanding rapidly. Average amount of satellite remote sensing image data are often large in GB as a unit. We consider the block, the index and build image pyramid the way to achieve large format satellite images of the display and roaming. Open the image from the machine and the amount of data size. . . Here the source code available to everyone.

Description: Decompose image into subbands, denoise, and recompose again.
fh = decomp_reconst(im,Nsc,Nor,block,noise,parent,covariance,optim,sig)
covariance: are we considering covariance or just variance?
optim: for choosing between BLS-GSM (optim = 1) and MAP-GSM (optim = 0)
sig: standard deviation (scalar for uniform noise or matrix for spatially varying noise)
Version using the Full steerable pyramid (2) (High pass residual
splitted into orientations).
