I want to make a 2x3 matrix on each component of an image. Attached is the picture.

Actually, I want to make a matrix, so that each dot in the picture lies in different index of the matrix. I need code. Kindly help please!

Your patterns appear to be 2x2 or 3x2 (rows by columns is the matlab convention), not 2x3.

An example of the desired output for the above input would clarify what you need.

You guessed it right. My mistake. I want 3x2 matrix. This is my actual image. These are braille dots. In Braille, Each letter is composed with the combination of 6 cells. So I have cropped each letter of Braille and made it a single component/image.

This is the cropped image.

Now I want to make a 3x2 matrix on each. so that each dot lies in each index of a matrix. Hope it is clear now! If not then you can ask more. I Need help!

Get a library of all possible dot patterns then just paste onto the desired location in your image. See my copy and paste code, attached.

You'll need to find whole rows, because otherwise you if you have, say, a pair of dots, you won't know if it's in the first row, second row, or third row. You won't know that with your method of dilating and taking the bounding box. So you're going to have to find tops and bottoms of the whole line of characters first. Then you can do what you said to get the right and left sides. THEN you can crop the bounding boxes, and then divide into 6 zones to determine what zones have a spot in them.
