图像翻转在OpenCV中调用函数flip()实现,原型如下: dst = cv2.flip(src, flipCode) 其中src表示原始图像,flipCode表示翻转方向,如果flipCode为0,则以X轴为对称轴翻转,如果fliipCode>0则以Y轴为对称轴翻转,如果flipCode<0则在X轴、Y轴同时翻转。 代码如下所示: 代码语言:javascript 代码运行次数:0
图像处理中的常见任务包括显示图像,基本操作如裁剪、翻转、旋转等,图像分割,分类和特征提取,图像恢复和图像识别。常用的基于 python 脚本语言开发的数字图片处理库有以下几种,比如 PIL,Pillow, opencv, scikit-image 等。(PIL 是针对 python2, pillow 是针对 python3,两者功能一样。) ...
import PIL.Image as Image 1. 2. 3. 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 #...
We know that an image is essentially a 3 Dimensional matrix, with each individual pixel containing a value for the Red, Green, and Blue channels. But we can actually use the beloved Pandas library to store each pixel as a separate data point. The below code does just that. def i...
图像处理(Image Processing)是指对图像进行分析、加工、和处理,使其满足视觉、心理或其他要求的技术。 图像滤波 图像滤波采用的是ImageFilter类,通过Image类的filter方法 def filter(self, filter): """ Filters this image using the given filter. For a list of ...
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)) ...
