Question 22
In the original U-Net used for dense prediction (and adaptable to depth estimation), each encoder stage applies two successive 3×3 convolutions with no padding (stride 1), followed by a 2×2 max-pooling with stride 2. If the input feature map to one such encoder stage has spatial size 132 × 132, what is the output height of the feature map after both convolutions and the max-pooling of that stage? The width is the same; enter one integer only.
