In this step-by-step tutorial, you'll learn how to use the Python Pillow library to deal with images and perform image processing. You'll also explore using NumPy for further processing, including to create animations.

A lot of applications use digital images, and with this there is usually a need to process the images used. If you are building your application with Python and need to add image processing features to it, there are various libraries you could use. Some popular ones areOpenCV,scikit-image,...
When you are done processing an image, you can save it to file with thesave()method, passing in the name that will be used to label the image file. When saving an image, you can specify a different extension from its original and the saved image will be converted to the specified form...
to post-processing the end result (similar to photo editing), the possibilities are much richer since computation can be enabled at every step of the photographic process—starting with the scene illumination, continuing with the lens, and eventually even at the display of the captured image. ...
Here we explore a couple of transformations where, using a function, each single pixel value from the input image is transferred to a corresponding pixel value for the output image. The function point() can be used for this. Each pixel has a value in between 0 and 255, inclusive. Log tr...
An image can be of the following different types:Single channel images—each pixel is represented by a single value: Binary (monochrome) images (each pixel is represented by a single 0-1 bit) Gray-level images (each pixel can be represented with 8-bits and can have values typically in ...
pillow.Image 小结 Python 中的图像处理模块 matplotlib.image 仅支持导入 PNG 格式的图像,且功能有限 PIL(Python Imaging Library) 功能丰富,简单易用 仅支持Python2.x版本, 且已经停止更新 pillow 在PIL的基础上发展而成的兼容版本 支持Python 3 此外,常用的图像处理模块还有skimage,cv2等 ...
