Please Can Somebody tell me how to add additional coins in the eight.tif image that is being copied from the database?

Hey Guys, How you doing? Please after you generate A=imread('eight.tif'); from Matlab database, what should you do to add additional coins in this image? Please give me a complete code that works to add this additional coins in that image.

Thank you in advance,

Jean

What have you tried so far and which problems have occurred?

Hello Mr. Simon, so far I have been trying so hard and used different avenues and could not get anything at all. Here is an example that I tried and gave errors: H=imread('eight.tif'); G=imread('coins.png'); F=imlincomb(0.5, H, 0.5, G); imshow(F) Error using imlincombc Function imlincomb expected its array input arguments (A1, A2, ...) to be the same size.

Error in imlincomb (line 84) Z = imlincombc(images, scalars, outputClass);

imlincomb() is just a weighted sum of two images, so the images have to be the same size. It will not paste a smaller image into a larger image.

I swear I already answered this today but it's no longer there or in your duplicate posting in the newsgroup http://www.mathworks.com/matlabcentral/newsreader/view_thread/324565#891884. I remember referring someone to my BlobsDemo Image Segmentation Tutorial and I said that to crop out coins and you could paste them back in. Since this might be a homework problem (since I've heard it more than once) I'll just give you a similar demo:

clc;    % Clear the command window.
close all;  % Close all figures (except those of imtool.)
imtool close all;  % Close all imtool figures.
clear;  % Erase all existing variables.
workspace;  % Make sure the workspace panel is showing.
format longg;
format compact;
fontSize = 20;

image1 = imread('moon.tif');
[rows1 columns1 numberOfColorChannels1] = size(image1)
subplot(2, 2, 1);
imshow(image1);
axis on;
title('Large Grayscale Image', 'FontSize', fontSize);
% Enlarge figure to full screen.
set(gcf, 'units','normalized','outerposition',[0 0 1 1]);

image2 = imread('cameraman.tif');
[rows2 columns2 numberOfColorChannels2] = size(image2)
subplot(2, 2, 2);
imshow(image2);
title('Small Grayscale Image', 'FontSize', fontSize);
axis on;

row1 = 30;
col1 = 51;
row2 = row1 + rows2 - 1;
col2 = col1 + columns2 - 1;

image1(row1:row2, col1:col2) = image2;
subplot(2, 2, 3);
imshow(image1);
axis on;
caption = sprintf('Small Image Pasted\ninto Large Image', 'FontSize', fontSize);
title(caption, 'FontSize', fontSize);

It works body and thank you. you are so good man
