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

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)
