Inverting a regularized Dix equation using the
![$ L2$](img2.png)
norm produces smooth interval velocity models. To get a blocky interval velocity estimate that is more geologically reasonable, a regularized Dix inversion needs to be done using an
![$ L1$](img3.png)
-like norm. In this paper, we compare different 2D regularizations using both the
![$ L2$](img2.png)
norm and the hybrid
![$ L1/L2$](img4.png)
norm to find the regularization that produces blocky velocity models while maintaining high accuracy and resolution. The results show that the hybrid
![$ L1/L2$](img4.png)
norm successfully achieves blockiness when using the first derivative in multiple directions as a regularization.
