光流图像配准

除了光流配准之外，还有其他配准方法，可以作对比。 具体使用方法可以看readme。

% [Ht G]=ComputeLKFlowParms（img）
%
% Computes the optical flow parameters. The image is derived in DX and DY
% directions and matrix G is computed.
%
% Inputs:
% img - The image to compute optical flow parameters. Note that the image
%       must contain a border of size 1 since the DX and DY operation work
%       on 3x3 regions.
%
% Outpus:
% Ht - The transpose of matrix H which defines the LK affine approximation of an shifted
% image
%
% G  - The matrix G=H‘*H
%
function [Ht G]=ComputeLKFlowParms（img）

% Compute Ix and Iy derivatives using sobel operator
Hdy = fspecial（‘sobel‘）;
Hdx = Hdy‘;

Ix=imfilter（img Hdx）;
Iy=imfilter（img Hdy）;

Ix=Ix（2:end-12:end-1）;
Iy=Iy（2:end-12:end-1）;

% Compute G
H = [Ix（:） Iy（:）];
Ht=H‘;
G=Ht*H;
