img-as-int

img_as_int

skimage.util.img_as_int(image, force_copy=False) [source]

Convert an image to 16-bit signed integer format.

Parameters:	image : ndarray Input image. force_copy : bool Force a copy of the data, irrespective of its current dtype.
Returns:	out : ndarray of uint16 Output image.

Notes

The values are scaled between -32768 and 32767. If the input data-type is positive-only (e.g., uint8), then the output image will still only have positive values.
