Error using vertcat Dimensions of matrices being concatenated are not consistent.

sir i m getting this error i dont know how to rectify it please help me

%%appendimages
% im = appendimages(image1, image2)
%
% Return a new image that appends the two images side-by-side.

function im = appendimages(image1, image2)

% Select the image with the fewest rows and fill in enough empty rows
%   to make it the same height as the other image.

rows1 = size(image1,1);
rows2 = size(image2,1);

if (rows1 < rows2)
     image1(rows2,1) = 0;
else
     image2(rows1,1) = 0;
end

% Now append both images side-by-side.

im = [image1 ; image2] %%in this line im getting error.

thanks with regards

@vani shree: please tell us the exact outputs from these commands:

size(image1)
size(image2)

[vani shree]

sir it does not show any output. but my input file of image1 and image 2 is

Instead of adding extra zeros, you can resize the images to same dimensions. you may consider the following:

I1 = imread('ORIGINAL1.jpg') ;
I2 = imread('FAKE.jpg') ;

if numel(I1)>numel(I2)
    I2 = imresize(I2,[size(I1,1) size(I1,2)]) ;
else
    I1 = imresize(I1,[size(I2,1) size(I2,2)]) ;
end
I12 = [I1  I2] ;
figure
imshow(I12)

I12 = [I1 ; I2] ;
figure
imshow(I12)

[vani shree]

sir i get rid of that error. but again one more error like " error using horzcat dimensions of matrics being concatenated are not consistent." error in I12 = [I1 I2] ; line

[KSSV]

What are sizes of I1 and I2 ?

[vani shree]

I1 size is 37 kb and 234*234 dimension I2 size is 32.7kb and 236*234 dimension

[Stephen23]

@vani shree: the two images have different numbers of rows, therefore cannot be concatenated horizontally.

[KSSV]

I said that, you can get them to same dimensions to join..I have given it in code..you accepted the answer and situation came to the question.

[vani shree]

sir i acccept that answer but still it is showing me the same error. please guide me sir. im new to matlab. wat do i do now? can i give the same size of image?

[vani shree]

same error i m getting sir" Error using horzcat Dimensions of matrices being concatenated are not consistent."

I12 = [I1 I2] ; in this line

[KSSV]

Attach the images with which you have tried the above code.

[vani shree]

good evening sir. origanal image will be my I1 and fake image will be my I2. sir i have attached my two images.

my code is

    % code
function im = appendimages(image1, image2)
if numel(image1)>numel(image2)
    image2 = imresize(image2,[size(image1,2) size(image1,2)]);
else
    image1 = imresize(image1,[size(image2,1) size(image2,2)]);
end
im = [image1 image2];
figure
imshow(im)

im = [image1 ; image2]; figure imshow(im)

this is my code sir. and i have attached sift function call code also thank you very much sir

sir please help me. i m doing project based on this code sir

[KSSV]

I will answer tomorrow..Morning.

[vani shree]

thank you so much sir

[vani shree]

my project title is Identifying fake products by matching their logos based on context. only 50% coding i have done sir. still matching process is pending.

[KSSV]

image1 = imread('FAKE.jpg') ;
image2 = imread('ORIGINAL.jpg') ;

if numel(image1)>numel(image2)
    image2 = imresize(image2,[size(image1,1) size(image1,2)]);
else
    image1 = imresize(image1,[size(image2,1) size(image2,2)]);
end
im = [image1 image2];
figure
imshow(im)
im = [image1 ; image2]; 
figure 
imshow(im)

I am not getting any error.

[vani shree]

sir did u gave fake and original imag ?

[vani shree]

sir when i run this code separately i m getting correct output. the problem is when i add function and map that function in another code file i m getting error sir. can you help me sir

[vani shree]

sir when i gave another image it is not running sir. it shows same error Error using horzcat Dimensions of matrices being concatenated are not consistent.

[KSSV]

Hello...Are both files RGB? There is a small correction...copy the code now and run.

[vani shree]

thank you sir.. its running successfully. thank you very much. you explained me well.

thank you sir for sharing this gui file. sir can u help me to run ASIFT code in matlab. i have tried but i dont know how to run this sir.
