scikit-image将8位图像读取为16位

Question

I am using both ImageJ and scikit-image to analyze 3D images. My original image is 16-bit and it is very big. I converted 16-bit image to 8-bit image in imageJ so that I can work easily.
Now when I am reading the image with scikit-image module both 16-bit and 8-bit image showing 16-bit only. Can anyone suggest how to read images as 8-bit in scikit-image module?

from skimage import io,color
image = io.imread(files)

Answer 1

You can perform the conversion through integer division ( // ) or bitwise right shift ( >> ) followed by type casting.

image = np.uint8(io.imread('Image8bit.tif') >> 8)

or

image = np.uint8(io.imread('Image8bit.tif') // 2**8)
