skimage

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., region properties and contours.

metrics

Metrics corresponding to images, e.g. distance metrics, similarity, etc.

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.
