27 个Python数据科学库实战案例 (附代码) 为了大家能够对人工智能常用的 Python 库有一个初步的了解,以选择能够满足自己需求的库进行学习,对目前较为常见的人工智能库进行简要全面的介绍。 1、Numpy NumPy(Numerical Python)是Python的一个扩展程序库,支持大量的...
先使用Matplotlib绘制堆积图,设置stackplot()的baseline参数,可将数据围绕x轴展示。 再通过scipy.interpolate平滑曲线,最终结果如下。 28. 时间序列图 时间序列图是指能够展示数值演变的所有图表。 比如折线图、柱状图、面积图等等。 import numpy as np import seaborn as sns import pandas as pd import matplotlib....

因为OpenCV文档中对Sobel算子的介绍中有这么一句:“in the case of 8-bit input images it will result in truncated derivatives”。即Sobel函数求完导数后会有负值,还有会大于255的值。而原图像是uint8,即8位无符号数,所以Sobel建立的图像位数不够,会有截断。因此要使用16位有符号的数据类型,即cv2.CV_16S。
