I got 3 color blob(1,2,3).
Firstly, I want to write a loop to create a table which state which blob is connected with another blob.
Then, I want try to merge them to form a same blob.How to solve this?

It's a poor description of what's going on. I'm going to assume you have an image that you thresholded to get a binary image and then you called bwlabel() and label2rgb() to colorize the blobs differently. So you should have the binary image already. If you don't for some reason, and you don't have the labeled image either, you can recover it from using any
binaryImage = logical(any(rgbImage, 3));

MyImage = imread('MyPicture.jpg')
PixelValue = MyImage(y,x); Gets the Pixel value at position y,x.
or using impixel to get it?

That will work for gray scale images. If it's color you need to do
PixelValue = MyImage(y, x, :);
or you can use impixel() for either color or gray scale images.
