imagesmosaicdemo.m

一个用MATLAB实现边缘检测的小程序！

%-------------------------------------------------------------------------
% image mosaicing demo program
% intro: this is a very simple demo program to join two images together
%        corners are pre-matched to be saved into cornerpairs.mat
% developed by bugzhao for evaluation use only, April 2005 [e-mail]
%-------------------------------------------------------------------------
function imagesmosaicdemo()
% read base image and the second image to be registered to the base image
close all;
unregistered = imread('q15.bmp');
baseimage=imread('b15.bmp');
figure,imshow(baseimage);
figure,imshow(unregistered);
% manually select point matches or automatically done by harris corner detector and CC matching
%load cornerpairs.mat;
round1=[44 50;58 63];
round2=[45 51;59 64];
t_concord = cp2tform(round1,round2,'linear conformal');
info = imfinfo('b15.bmp');
registered = imtransform(unregistered,t_concord,'XData',[1 info.Width], 'YData',[1 info.Height]);
figure,imshow(registered);
% do blending work using simplest pixel average
M=baseimage;
for row=1:info.Height
    for col=1:info.Width
        if(registered(row,col,1)~=0 && col<640)
            M(row,col,:)=(double(registered(row,col,:))+double(baseimage(row,col,:)))/2;
        end
        if(registered(row,col,1)~=0 && col>640)
            M(row,col,:)=double(registered(row,col,:));
        end
    end
