Get border pixels of labelled region

[Payal Gupta]

hello everyone...
i will try this code,in this  i want to do read a image then do edge
detection after that find the boundaries of image object. but
find_boundaries return me a bool array but i need a integer array. is it
any solution of this.


code::

import Image

from skimage import segmentation as seg,io,filter

imge = io.imread("IMG_1.jpg")

 thresh = filter.threshold_otsu(imge)

binary = imge> thresh

edge_canny = filter.canny(binary)

bimg =seg.find_boundaries(binary)

print(bimg)

fig, (ax0, ax1) = plt.subplots(ncols=2)

ax0.imshow(bimg,cmap=plt.cm.gray)
ax1.imshow(binary,cmap=plt.cm.gray)
