How can I link the last white dot line pixels of the image?

Hi

I want to link the last white pixels (lines,dots) of the image as you see it. Measuring from bottom to top of the image are the first white dot like pixels you see.

Thank you

How can I link the last white dot line pixels of the image?

link with whom?

Please explain better - it's not remotely clear what's being asked for.

[Stelios Fanourakis]

The last white pixels are like random dots or short little lines in a flow like a wave. Please, see the last white pixels on the image or the first white pixels as you count from bottom to top. I need to connect those white little short lines between them to create that kind of flow/wave as a curve line.

"the first white pixels as you count from bottom to top"

I don't know what this means. Do you mean the bottom-most white pixel in each column of the image?

[Stelios Fanourakis]

Yeah. The last white pixels of every column. If you notice they form a wave shape curve between them. Can I connect them?

This assumes that every column has at least one white pixel in it:

Image=cumsum(Image,1,'reverse')>0;

B=bwboundaries(Image);

newImage=accumarray(B{1},1,size(Image)) ;

imshow(newImage)
