"""Image Processing SciKit (Toolbox for SciPy)
``scikit-image`` (a.k.a. ``skimage``) is a collection of algorithms for image
processing and computer vision.
The main package of ``skimage`` only provides a few utilities for converting
between image data types; for most features, you need to import one of the
following subpackages:
Subpackages
-----------
color
Color space conversion.
data
Test images and example data.
draw
Drawing primitives (lines, text, etc.) that operate on NumPy arrays.
exposure
Image intensity adjustment, e.g., histogram equalization, etc.
feature
Feature detection and extraction, e.g., texture analysis corners, etc.
filters
Sharpening, edge finding, rank filters, thresholding, etc.
graph
Graph-theoretic operations, e.g., shortest paths.
io
Reading, saving, and displaying images and video.
measure
Measurement of image properties, e.g., similarity and contours.
morphology
Morphological operations, e.g., opening or skeletonization.
novice
Simplified interface for teaching purposes.
restoration
Restoration algorithms, e.g., deconvolution algorithms, denoising, etc.
segmentation
Partitioning an image into multiple regions.
transform
Geometric and other transforms, e.g., rotation or the Radon transform.
util
Generic utilities.
viewer
A simple graphical user interface for visualizing results and exploring
parameters.
Utility Functions
-----------------
img_as_float
Convert an image to floating point format, with values in [0, 1].
img_as_uint
Convert an image to unsigned integer format, with values in [0, 65535].
img_as_int
Convert an image to signed integer format, with values in [-32768, 32767].
img_as_ubyte
Convert an image to unsigned byte format, with values in [0, 255].
