+"""Image Processing for Python
+
+``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.
+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].
+    Is similar to `img_as_float64`, but will not convert lower-precision
+    floating point arrays to `float64`.
+img_as_float32
+    Convert an image to single-precision (32-bit) floating point format,
+    with values in [0, 1].
+img_as_float64
+    Convert an image to double-precision (64-bit) 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].
+img_as_bool
+    Convert an image to boolean format, with values either True or False.
+dtype_limits
+    Return intensity limits, i.e. (min, max) tuple, of the image's dtype.
