function

skimage.util.dtype:img_as_float

source: /dev/scikit-image/src/skimage/util/dtype.py :479

Signature

def   img_as_float ( image ,  force_copy = False )

Summary

Convert an image to floating point format.

Extended Summary

This function is similar to img_as_float64, but will not convert lower-precision floating point arrays to float64.

Parameters

image : ndarray

Input image.

force_copy : bool, optional

Force a copy of the data, irrespective of its current dtype.

Returns

out : ndarray of float

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].
