python - OpenCV - Reading a 16 bit grayscale image -

-

i'm trying read 16 bit grayscale image using opencv 2.4 in python, seems loading 8 bit.

i'm doing:

im = cv2.imread(path,0) print im  [[25 25 28 ...,  0  0  0] [ 0  0  0 ...,  0  0  0] [ 0  0  0 ...,  0  0  0] ...,

how 16 bit?

figured out. in case else runs problem:

im = cv2.imread(path,-1)

setting flag 0, load grayscale seems default 8 bit. setting -1 loads image "as is".
