说明： 一种比sift效果更好的算法，可实现图像在几乎任意仿射变化下的特征提取，而且特征点比SIFT多，是09年最新的算法
(asift, full name is the affine scale-invariant feature transform, that is, of scale-invariant features of affine transform, is used to extract more of the characteristics of affine distortion of the same region, a method useful for all of us believe that ~ ~ ~)

===========================================================================
Welcome to use the Affine-SIFT (ASIFT) software.
ASIFT permits image comparison independent to viewpoint change
The ASIFT software supports currently Linux/Unix/Windows.
Windows version is provided by Pierre Moulon.
The input images could be in GRAY-LEVEL or COLOR images (on windows).
In order to limit the computational time, it is better to to test on input images with less than
300000 pixels. For example an image size 600x450 (or 512x512) is O.K.
The windows version is not multhreaded yet.

A website with an online demo is available.
http://www.cmap.polytechnique.fr/yu/research/ASIFT/demo.html.
It allows the users to test ASIFT online with their own images. It also contains an image dataset (for systematic
evaluation of robustness to absolute and transition tilts), and more examples.

Short Manual
1. Unzip and save all the files in one directory. Go to that directory.
2. Run one of the sample bat file (For example LauncherWithArguments).
3. Check the results files (match_LR.txt match_HR.txt and the two images result_LR.jpg, result_HR.jpg that display the matches)
3. Call LauncherWithArguments with your own files. Show usage by calling "LauncherWithArguments.bat" in a cmd window.
3.1. Example : LauncherWithArguments.bat Adam1.pgm Adam2.pgm 0 matchLR.tiff matchHR.tiff coorLR.txt coorHR.txt
======
Short Manual == Matlab launching script.
1. Add the Asift executables directory as a path of your Matlab.
2. Use the SimpleAsiftMatlab.m function
3. [coordA,coordB] = SimpleAsiftMatlab('Adam1.pgm','Adam2.pgm',0,'matchLR.tiff','matchHR.tiff','coorLR.txt','coorHR.txt');
4. coordA and coordB contains the Asift matches that are contained in coorLR.txt and coorHR.txt (the output of ASIFT).
5. The displayed image show the ASIFT matches too.
------------------------------
===========================================================================
ATTENTION:
This alpha version may have some problem on the Image output interface with some certain type of images.
Prefer to use the jpg/bmp/tiff/tga/png/pgm format.
If you encounter this bug, please
1. Use the online version instead.
http://www.cmap.polytechnique.fr/yu/research/ASIFT/demo.html
It is the same program but more stable.
2. Report the bug to yu@cmap.polytechnique.fr. We appreciate a lot your help.
