Write a filter like those in the previous two exercises that creates a wave effect, by copying

Question:

Write a filter like those in the previous two exercises that creates a wave effect, by copying the color of each pixel $\left(s_{i}, s_{j}ight)$ in the source image to a target pixel $\left(t_{i}, t_{j}ight)$, where $t_{i}=s_{i}$ and $t_{j}=s_{j}+20 \sin \left(2 \pi s_{j} / 64ight)$. Add code to take the amplitude (20 in the accompanying figure) and the frequency (64 in the accompanying figure) as command-line arguments. Experiment with various values of these parameters.
