Hello,

I'm new to Matlab and I'm trying to do a Control Point Registration using your guide: http://www.mathworks.com/help/images/point-mapping.html

The result I get is two pictures one on top of the other but they are misaligned .

Can you please tell me what am I doing wrong ?

Thank you.

Here is the code:

function [Y] =EBL
 ReferenceImg=imread('GFI.jpg'); %This is the fixed image
 CroppedImg=imcrop(ReferenceImg); %Crop fixed image
 close %close the imcrop window
 MovingImg = imread('GF.bmp'); %This is the moving picture
 ResizedIReferenceImg= imresize(CroppedImg,[1000 1000]); %resize the fixed image
 ResizedMovingImg= imresize(MovingImg,[1000 1000]);%resize the moving image
 [input_points,base_points] = cpselect(ResizedMovingImg,ResizedIReferenceImg,'Wait', true);%Estimate   transformation
 tform = fitgeotrans(input_points,base_points,'projective');
 B = imwarp(ResizedMovingImg,tform);
 imshow(B)
 hold on
 t=imagesc(ResizedIReferenceImg);%Set transparency of fixed image
 set(t,'AlphaData',0.5);
