skimage.filter has been removed. Use skimage.filters instead.
skimage.filters.canny has been removed.
canny is available only from skimage.feature now.
Deprecated filters hsobel, vsobel, hscharr, vscharr, hprewitt,
vprewitt, roberts_positive_diagonal, roberts_negative_diagonal have
been removed from skimage.filters.edges.
The sigma parameter of skimage.filters.gaussian and the selem parameter
of skimage.filters.median have been made optional, with default
values.
The clip_negative parameter of skimage.util.dtype_limits is now set
to None by default, equivalent to True, the former value. In version
0.15, will be set to False.
The circle parameter of skimage.transform.radon and skimage.transform.iradon
are now set to None by default, equivalent to False, the former value. In version
0.15, will be set to True.
Parameters ntiles_x, ntiles_y have been removed from
skimage.exposure.equalize_adapthist.
The freeimage io plugin is no longer supported, and will use imageio
instead. We will completely remove the freeimage plugin in Version 0.14.
equalize_adapthist now takes a kernel_size keyword argument, replacing
the ntiles_* arguments.
The functions blob_dog, blob_log and blob_doh now return float
arrays instead of integer arrays.
transform.integrate now takes lists of tuples instead of integers
to define the window over which to integrate.
reverse_map parameter in skimage.transform.warp has been removed.
enforce_connectivity in skimage.segmentation.slic defaults to True.
skimage.measure.fit.BaseModel._params,
skimage.transform.ProjectiveTransform._matrix,
skimage.transform.PolynomialTransform._params,
skimage.transform.PiecewiseAffineTransform.affines_* attributes
have been removed.
skimage.filters.denoise_* have moved to skimage.restoration.denoise_*.
Change default value of sigma parameter in skimage.segmentation.slic
to 0
hough_circle now returns a stack of arrays that are the same size as the
input image. Set the full_output flag to True for the old behavior.
The following functions were deprecated over two releases:
skimage.filter.denoise_tv_chambolle,
skimage.morphology.is_local_maximum, skimage.transform.hough,
skimage.transform.probabilistic_hough,`skimage.transform.hough_peaks`.
Their functionality still exists, but under different names.
