I have used this code.

ppic=eyes.binarize(blocksize=21).edges() blobs=ppic.findBlobs( minsize=1,maxsize=0,appx_level=0) for b in blobs: b.draw() ppic.show()

Result: eyes canny edge https://www.dropbox.com/s/gy23g5n18ohhia1/2.jpg

I thought that each white pixel should be considered to be inside the blob but the result's shown that there are some pixels that are not cosidered to be inside any blob. why has this happened? I expect all pixels being lebeled as the part of a blob. Thank you in advance for your suggestion.
