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。

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.
