I have attached 'm1.jpg' with this queation. I have placed a red colored boxes around the collection of white dots in the image where I want to get only one white dot in replacement of the bunch of white dots. Is there any function or trick you suggest. Please share an automated solution.

Get the locations of the points using find..group them and use mean to each group. YOu will get a single point.

I have written this command

I1 = imread('m1.jpg')

[X,Y] = find(I1);

R1 = [X(1),Y(1)]

R2 = [X(2),Y(2)]

and so on till

Rm = [X(m),Y(m)]

now, kindly mention how may I group these points before getting mean

You can use kmeans() if you have the Statistics and Machine Learning Toolbox. It will give you the cluster centroids.
