`skimage.util.dtype:img_as_float32`

source: /dev/scikit-image/src/skimage/util/dtype.py :427

Signature

def img_as_float32 ( image , force_copy = False )

Summary

Convert an image to single-precision (32-bit) floating point format.

Parameters

image : ndarray: Input image.
force_copy : bool, optional: Force a copy of the data, irrespective of its current dtype.

Returns

out : ndarray of float32: Output image.

Notes

The range of a floating point image is [0.0, 1.0] or [-1.0, 1.0] when converting from unsigned or signed datatypes, respectively. If the input image has a float type, intensity values are not modified and can be outside the ranges [0.0, 1.0] or [-1.0, 1.0].
