Amaxmaximdiff; find the max value in the imdiff
BimdiffA;use a logic array return a 1 at the location of the max value
maxlocationfindB;find function give the location of the max value in linear indices

hold on
i,jind2subsizeimdiff,maxlocation; ind2sub give the row and column of the location of the max value
plotj,i,.r;i, j are row and column, so j is actually x index and i is y index, and plot the point.
textj,i,max,color,red;use index i and j, and add text to it.
hold off
