Getting Started with Scikit-image: Image Processing in Python

| | | |

Important features of scikit image:

Simple and efficient tools for image processing and computer vision techniques.
Accessible to everybody and reusable in various contexts .
Built on the top of NumPy, SciPy, and matplotlib.
Open source, commercially usable - BSD license.

Note. Make sure NumPy and SciPy are preinstalled before installing scikit-image. Now the easiest way to install scikit image — use pip :

 pip install -U scikit-image 

Most of the ski wizard’s functions are inside submodules. Images are represented as NumPy arrays, such as 2D arrays for 2D grayscale images.

Code # 1:

# Python3 processing program
# images using skikit-image

# import data from the ski mage

from skimage import data


camera = data. camera () 

# 512-line image
# and 512 columns

type (camera) 


print (camera.shape)


 numpy.ndarray (512, 512) 

Code # 2: The submodule provides a set of functions that return sample images.

# Python3 processing program
# images using skikit-image

# import filters and
# data from the ski mage

from skimage import filters

from skimage import data

# Predefined function to retrieve data

coins = data.coins () 

# how to find the threshold

threshold_value = filters.threshold_otsu (coins) 


print (threshold_value)



Code # 3: Upload your own images as NumPy arrays from image files.

< tbody>

# Python3 processing program
# images using skikit -image

import os

# import from ski mage

import skimage

from skimage import io

# way to load car image from file

file = os.path.join ( (skimage.data_dir, ’cc.jpg’ )


 < / p>

cars = io.imread ( file )

# a way to show the input image
io.imshow (cars)
io .show ()



  • Medical image analysis.
  • Image classification for detection.
