How can I mosaic two images

I want to mosaic two imges using MATLAP script

would do you help me how I will Image Stitching?

Please, help me by providing its codes

Answer 1

[Image Analyst]

Try imtile() or montage() or imshowpair().

Or try this:

tallImage = [image1;image2];  % Must have same number of columns and color channels.
wideImage = [image1, image2]; % Must have same number of rows and color channels.

1. Read both the images using imread.
2. Check the sizes of both the images.
3. Convert the images two same size if they are not in same size using imresize.
4. Join both the images using cat.

I1 = imread(image1) ;  %m,n size
I2 = imread(image2) ;  % m,n size 
% Merge next to each
I12 = cat(2,I1,I2) ; 
imshow(I12)  
% Merge one above the other
I12 = cat(1,I1,I2) ;
imshow(I12)

Dear KSS for your on time response. But when I use your code to mosaic two images the following errors comes. And it is not working. Would re-vist it?

imshow(I12)

Error using cat

Dimensions of arrays being concatenated are not consistent.

>> I12 = cat(1,I1,I2) ;

imshow(I12)

Error using cat

Dimensions of arrays being concatenated are not consistent.

[KSSV]

I have already specified that both the images should be of same dimension. Use imresize to get them to the same dimensions.

[Mekonen Merga Iticha]

Since I am the bigginer for this kind of analysis, would provide the imresize code as well. That image I am working on is two, which is obtained from urban area. Also, I am waiting your response that I send to you personally

[KSSV]

I1 = imread(image1) ; 
I2 = imread(image2) ;
[m1,n1,p1] = size(I1) ; 
[m2,n2,p2] = size(I2) ; 

m = max(m1,m2) ;
n = max(n1,n2) ;
I1 = imresize(I1,[m,n]) ;
I2 = imresize(I2,[m,n]) ; 
I12 = cat(1,I1,I2) ; 
imshow(I12)

[Mekonen Merga Iticha]

This works, but still it has a problem. I makes stick together on the top of the other images. But, it does not mosaicked the images. I need as they mosaic

sorry for the disturbance I made

[KSSV]

What do you mean by mosiac?? Show example.

[Mekonen Merga Iticha]

When I say mosaic, I mean that producing one image from two images. Just overlaying one on the other, ruther that merging one image over the top of the other.

Answer 3

[Mekonen Merga Iticha]

The code you provide works for "Merge one above the other". But, I needs overlaying or mosacking rather than merging one above the other

[KSSV]

Try montage function.

[Mekonen Merga Iticha]

When I say mosaic, I mean that producing one image from two images. Just overlaying one on the other, ruther that merging one image over the top of the other.

[Mekonen Merga Iticha]

I could not now the function of montage yet

[Mekonen Merga Iticha]

When I say mosaic, I mean that producing one image from two images. Just overlaying one on the other, ruther than merging one image over the top of the other.

[Mekonen Merga Iticha]

When I say mosaic, I mean that producing one image from two images. By using matching principles, and feature extractions overlaying two images. Example using the prinples of Harris

points1 = detectHarrisFeatures(I1);

points2 = detectHarrisFeatures(I2);
