We will be flipping the SciPy Lena image—all in the name of science, of course, or at least as a demo. In addition to flipping the image, we will slice it and apply a mask to it.
The steps are as follows:
- Flip the Lena array around the vertical axis using the following code:
- Take a slice out of the image and plot it. In this step, we will take a look at the shape of the Lena array. The shape is a tuple representing the dimensions of the array. The following code effectively selects the top-left quadrant of the Playboy picture:
- Apply a mask to the image by finding all the values in the Lena array that are even (this is just arbitrary for demo purposes). ...
