WitrynaThe imshow () function from Matplotlib provides many different types of interpolation methods to plot an image. These functions can be particularly useful when the image to be plotted is small. Let us use the small 50 x 50 lena image shown in the next figure to see the effects of plotting with different interpolation methods: WitrynaBy default (which is changed mpl 2.0), imshow interpolates the data (as you would want to do for an image). All you need to do is tell it to not interpolate: im = plt.imshow (..., …
