Description: GDAL支持的Morton 编码金字塔无缝漫游工具，从2007年开始，不断更新到2011年，偶的小业余研究。底层基于GDAL, 支持很多冷门格式。使用Morton金字塔重构二维数据，加上内存映射文件的帮助，浏览GB级影像没有问题。内嵌带接缝处理的透明分块条带处理接口，无需了解金字塔，也能透明对GB级影像进行各种处理。内嵌直方图均衡和模板卷积的例子，演示如何透明的开发处理算法。附带重要的功能是“尺度不变特征SIFT”的特征提取，本来是上学时的论文，经过这些年零敲碎打的改造，现在能进行全自动、半自动、手动控制点提取、模型最小二乘估计，纠正功能，最终把偶的风景照拼接成全景。由于离开原先行业，没再用真正的遥感图试过，只当好玩吧！内附代码、范例、详细说明书。性能肯定不如SIFT原版范例。

http://www.pudn.com/downloads372/sourcecode/graph/texture_mapping/detail1607889.html-Morton GDAL support seamless roaming pyramid coding tools, beginning in 2007, constantly updated to 2011, even the little amateur research. Bottom based on GDAL, support for many unpopular formats. Reconstruction of two-dimensional data using the Morton pyramid, with the help of memory mapped files, browse the GB-level image is no problem. Embedded with the seaming strip of transparent block processing interface, no understanding of the pyramid, but also transparent to the GB-level images of various processing. Embedded histogram equalization and template convolution example, shows how transparent the development of processing algorithms. With important function is to "scale-invariant features of SIFT" feature extraction, could have been school papers, after all these years of piecemeal reform, now fully automatic, semi-automatic, manual control points extraction, model least squares estimation to correct function, eventually even spliced into a panoramic landscape photo.

使用 Matlab+C++混合编程的SIFT特征提取与匹配演示程序，很完整，是 Morton金字塔无缝漫游 GDAL SIFT 照片配准系统 的底层算法，很适合研究改进。使用这个库的成套系统见

SIFT multi Octave 是纯 Matlab 的演示版，速度很慢，但是可读性好
运行MakeSampleData.m启动测试程序, 双击生成的工作区(mat)，调用
ShowResult(Results) 显示结果。
SIFT_C redist 是Matlab + C 的混合程序，需要首先编译siftFeatureMaker工程，把 Dll 和 Exe 拷贝到
SIFT_C redist\CoreCode
里面，如果不是Matlab R2011a ，请重新编译Mex，运行
SIFT_C redist\CoreCode\compileMex.m
编译所有的C语言Mex文件
运行MakeSampleData.m启动测试程序, 双击生成的工作区(mat)，调用
ShowResult(Results) 显示结果。
请在安装了Visual Studio 2008 最小运行时的机器上运行这个程序。 -Written using Matlab+ C SIFT feature extraction and matching algorithms, the pyramid is the Morton photo with seamless roaming GDAL SIFT Barebone underlying algorithms. http://download.csdn.net/source/3028945
