Hi,
I have extracted some pixels (based on some criteria ) from image A and got Image B
as shown below.

Now, I need to connect each pair pixel of Image B, if the corresponding points/pixels are connected in A?? How to do that.???

Very easy. Just call bwlabel on A
[labeledImage, numRegions] = bwlabel(A);
where A is a binary image.
Then use find() and pdist2() (stats toolbox) on B to get distances and select the smallest non-zero distance - trivial, but let me know if you can't do it.
Then, for your two pixels locations in B you want to check on, simply check if the labels are the same or different.
if labeledImage(row1, col1) == labeledImage(row2, col2)
% Those two locations in B are on the same curve in A
else
% Those two locations in B are on different curves in A
end

and then upload your original image A and image B. Also provide what you'd like your final image to look like - mock something up in Photoshop if you have to.
