用python进行图像处理中分别用到过matplotlib.pyplot、PIL、cv2三种库,这三种库图像读取和保存方法各异,并且图像读取时顺序也有差异,如plt.imread和PIL.Image.open读入的都是RGB顺序,而cv2.imread读入的是BGR顺序。使用时需要倍加注意。 1. cv2,matplotlib,PIL比较 读取图像 1.cv2.imr
在Matplotlib图中显示数据可以通过以下步骤实现: 1. 导入必要的库: ```python import matplotlib.pyplot as plt ``` 2. 创建数据: ```...
基于matplotlib和plottable库绘制精美表格 plottable是一个Python库,用于在matplotlib中绘制精美定制的图形表格。plottable的官方仓库地址为:plottable。本文主要参考其官方文档,plottable的官方文档地址为:plottable-doc。plottable安装命令如下: pip install plottable 本文所有代码见:Python-Study-Notes 目录 1 使用说明 1...
import matplotlib.pyplot as plt plt.savefig() 1 2 当然我们也可以使用:plt.imshow()#或者plt.plot() 看你保存的是图像数据还是fig曲线数据plt.show()会出现一个gui画面,gui中有保存数据的按钮。 Opencv读取图片这里就不多介绍了,主要就是利用cv2.imread()来读取图片。 保存的话可以使用下面的函数: cv2.im...
