image-stitching 实验两张图片的拼接

实验两张图片的拼接，对于图片中的匹配对，用ransac方法消除错配，并估计出仿射矩阵。然后将一张图进行仿射变换，再实现拼接

% AFFINEFUNDMATRIX - computes affine fundamental matrix from 4 or more points
%
% Function computes the affine fundamental matrix from 4 or more matching
% points in a stereo pair of images.  The Gold Standard algorithm given
% by Hartley and Zisserman p351 （2nd Ed.） is used. 
%
% Usage:   [F e1 e2] = affinefundmatrix（x1 x2）
%          [F e1 e2] = affinefundmatrix（x）
%
% Arguments:
%          x1 x2 - Two sets of corresponding point.  If each set is 3xN
%                   it is assumed that they are homogeneous coordinates.
%                   If they are 2xN it is assumed they are inhomogeneous.
%         
%          x      - If a single argument is supplied it is assumed that it
%                   is in the form x = [x1; x2]
% Returns:
%          F      - The 3x3 fundamental matri
