These are some basic algorithms that I have implemented by my hands in the process of learning digital image processing, such as mean and median filtering, sharpening algorithms, interpolation scaling algorithms, histogram equalization algorithms, etc.

文件目录：

• filter : 滤波，代码都在 image_filter.py中，目前有

  • 均值滤波
  • 中值滤波

• sharpen: 锐化，现在只有基于 拉普拉斯算子的锐化算法。

• Interpolation: 内插，用于图像的缩放，目前有

  • 最近邻内插 - NNI.py

  • 双线性内插 - BLI.py

  • 双立方内插（双三次内插）- BCI.py

• Histogram equalization：直方图均衡化 - image_HE.py
