Module: util¶
| skimage.util.img_as_float(image[, force_copy]) | Convert an image to double-precision floating point format. |
| skimage.util.img_as_int(image[, force_copy]) | Convert an image to 16-bit signed integer format. |
| skimage.util.img_as_ubyte(image[, force_copy]) | Convert an image to 8-bit unsigned integer format. |
| skimage.util.img_as_uint(image[, force_copy]) | Convert an image to 16-bit unsigned integer format. |
img_as_float¶
- skimage.util.img_as_float(image, force_copy=False)¶
Convert an image to double-precision floating point format.
Parameters : image : ndarray
Input image.
force_copy : bool
Force a copy of the data, irrespective of its current dtype.
Returns : out : ndarray of float64
Output image.
Notes
The range of a floating point image is [0, 1]. Negative input values will be shifted to the positive domain.
img_as_int¶
- skimage.util.img_as_int(image, force_copy=False)¶
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
If the input data-type is positive-only (e.g., uint8), then the output image will still only have positive values.
img_as_ubyte¶
- skimage.util.img_as_ubyte(image, force_copy=False)¶
Convert an image to 8-bit unsigned 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 ubyte (uint8)
Output image.
Notes
If the input data-type is positive-only (e.g., uint16), then the output image will still only have positive values.
img_as_uint¶
- skimage.util.img_as_uint(image, force_copy=False)¶
Convert an image to 16-bit unsigned 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
Negative input values will be shifted to the positive domain.
