    Hello, I wonder how to read the data in the .sift files for the SIFT feature point information such as feature point numbers and the 128 dimension descriptors for each feature point. 
    Is there any existing code for me for reference?
    I have found the C++ code which maybe can help me to sovle it: ccwu.me/vsfm/MatchFile.zip   But I do not know how to utilize the functions to write the main.cpp to do what I want.
    Can someone help me? Thanks a lot.
