OpenCV-Python is not only fast since the background consists of code written in C/C++ but is also easy to code and deploy (due to the Python wrapper in the foreground). OpenCV-Python is the Python API for OpenCV. OpenCV (Open Source Computer Vision Library) is one of the most widely used libraries for computer vision applications. Python Image Processing Tutorial for Beginners with Python PIL Usage Enhance an Image Using ImageFilter from PIL import Image, ImageFilterĮnh.enhance(1.8).show("30% more contrast") Image source The documentation has instructions for installation and examples covering every module of the library. The library contains basic image processing functionality, including point operations, filtering with a set of built-in convolution kernels and color space conversions. Fortunately, we have Pillow, an actively-developed fork of PIL which is easier to install, runs on all major operating systems and supports Python 3. However, its development has stagnated, with its last release in 2009. PIL (Python Imaging Library) is a free library for the Python programming language that adds support for opening, manipulating and saving many different image file formats. You can find a complete list of resources and documentation on NumPy’s official documentation page. You can then load the image using skimage and display it using Matplotlib. Therefore, by using basic NumPy operations, such as slicing, masking and fancy indexing, we can modify the pixel values of an image. An image is essentially a standard NumPy array containing pixels of data points. NumPy is one of the core libraries in Python programming and provides support for arrays. You can find more examples in the gallery. You can do this by using the match_template function. Plt.imshow(edges, cmap='gray') Template Matching Some examples of skimage include: Image Filtering import matplotlib.pyplot as plt You can import the package as skimage and most functions are found within the submodules. Scikit-learn has been well documented with many examples and practical use cases. This code is high quality, peer-reviewed and written by an active community of volunteers. Scikit-image is a relatively straightforward library, even for those new to Python’s ecosystem. It implements algorithms and utilities in research, education and industry applications. Scikit-image is an open-source Python package that works with NumPy arrays. More From Our Python Experts Python Databases 101: How to Choose a Database Library
