How about assigning the spot you want to an output image:

desiredSpotImage =zeros(size(initial_Image));
desiredSpotImage(row1:row2, column1:column2) =
initial_Image(row1:row2, column1:column2):

or something like that?

Or you can erase the other two spots like this:

initial_Image(row1:row2, column1:column2) = 0;
initial_Image(row3:row4, column3:column4) = 0;

Of course you need to figure out what the starting and ending row and
column numbers are but that shouldn't be two hard for well separated
spots like you showed. If the clusters overlap then you have a bigger
problem.
