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.
PIL.Image是 Pillow / PIL 中最重要的模块。其中定义了class Image:,通过其中的函数、方法和属性,可以完成对图像的读取、显示和简单的操作。可以通过多种方式创建该类的实例:可以从文件中加载图像,处理其他图像,或者从头创建图像。 pillow.Image 常用函数 # 读取图像文件 # Image.open("图片路径") img = 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...

Image Processing with PythonTo provide a tutorial guide to image processing. To show how to manipulate images. To provide tools to analyze images. To introduce fast Fourier transforms.doi:10.1007/978-3-319-78145-7_18Stephen Lynch
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...

在用python 进行图像处理的时候,为了提高执行效率,必定会用到 numpy 数据类型,以下介绍了图像处理中 numpy 中常用的语法,希望对大家有帮助。 1. numpy 倒置数组(第一个值到最后一个值,最后一个值到第一个值) In [2]: a = np.random.randint(0, 20, (6, 2)) ...
