Comparing the dots in two images and eliminating the dots which don't have pairs

Hi,

I have two images which is basically dot patterns. One is an initial image where there is only round dots. Second image is taken when we place a thin film on water above the dot pattern where some dots are dilated and some are convereged. I want to compare these dots in both the images and eliminate those which does not have the corresponding pairs.If anyone could resolve the problem please message.

Thanks

See this example

A1 = imread('image1.png');
A2 = imread('image2.png');
I1 = rgb2gray(A1);          % convert ot grayscale
I2 = rgb2gray(A2);
B1 = im2bw(I1);             % binarize image
B2 = im2bw(I2);
BB = B1 & B2;               % find dots on both images
II = I1 .* BB;
imshow(II)

Thanks,

But I have to compare both the images and find the corresponding pair and delete the dots which dont have the pair automatically.
