python-image tools: matplotlib

本文详细介绍了如何使用matplotlib.pyplot中的imshow()函数正确显示图像。当图像数据格式为(channels, imagesize, imagesize)时,需要通过numpy的transpose函数将其转换为(imagesize, imagesize, channels)格式,以符合imshow()的输入要求。
  • imshow()
    • plt.imshow(np.transpose(npimg, (1, 2, 0)))。

      因为在plt.imshow在现实的时候输入的是
      (imagesize,imagesize,channels)

      imshow中,参数img的格式为(channels,imagesize,imagesize),

      这两者的格式不一致,我们需要调用一次np.transpose函数,即np.transpose(npimg,(1,2,0)),
      将npimg的数据格式由(channels,imagesize,imagesize)转化为(imagesize,imagesize,channels),进行格式的转换后方可进行显示
