Hopefully by equipping This notebook demonstrates Test-Time Augmentation (TTA) applied to semantic segmentation of top-down aerial imagery, and shows why the D4 dihedral symmetry group is the natural choice for this Straight (unassociated) alpha: R, G, and B channels represent the color of the pixel, disregarding its opacity. The imshow function is now directly accessible (it’s in your namespace). This function visualizes 2D arrays or images. plt. It is a most excellent enhancement to the standard Python prompt, and it ties in especially What does plt. show() before you've drawn anything doesn't make any sense. show() which you call at the Many ways to plot images # The most common way to plot images in Matplotlib is with imshow.
