作者:Parul Pandey 编译:大数据文摘 本文主要介绍了一些简单易懂最常用的Python图像处理库 当今世界充满了各种数据,而图像是其中高的重要组成部分。然而,若想其有所应用,我们需要对这些图像进行处理。图像处理是分析和操纵数字图像的过程,旨在提高其质量或从中提取一些信息,然后将其用于某些方面。 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等。Python之成为图像处理任务的最佳选择,是因为这一科学编程语言日益普及,并且其自身免费提供许多最先进的图像处理工具。 让我们看一下用于图像处理任务的一些常用Python库。 1. scikit Image scikit-image是一个基于numpy数组的开源Python包。 它实现了用于研究、教育和工业应用的算法和实用程序。 即使是对于那些刚接触Python的人,它也是一个相当简单的库。 此库代码质量非常高并已经过同行评审,是由一个活跃的志愿者社区编写的。 使用说明文档: https://scikit-image.org/docs/stable/user_guide.html 用法举例: 图像过滤、 模版匹配 可使用“skimage”来导入该库。大多数功能都能在子模块中找到。 import matplotlib.pyplot as plt %matplotlib

uEye camera with python on Windows

Since uEye cameras are widely spread industrial cameras I would have thought that there is a standard solution to this; however, I could not find any. The solution needs to run under python 2.7 on Windows XP or Windows 7. I would appreciate anyone who has successfully used a uEye camera in python on Windows to share his knowledge on this issue or at least point me in the right

OpenCV FloodFill with multiple seeds

爱⌒轻易说出口 提交于 2019-12-22 11:03:03
问题 Is there a floodFill function for python/openCV that takes a list of seeds and starts changing the color of its neighbours? I know that simplecv as a function like that SimpleCV floodFill. OpenCV says it has two floodFill functions when that uses a mask and another one that doesn't, documentation, I'm not being able to use the opencv floodfill function without a mask and with a list of seeds. Any help? This is what I'm trying to do so far: A=array([[0,1,1,0],[0,0,0,0],[1,1,1,1],[1,1,1,1]],np
