“…In our numerical experiments, the AITV Poisson SaT/SLaT yielded high-quality segmentation results within seconds for various grayscale and color images corrupted with Poisson noise and/or blur. For future directions, we are interested in other nonconvex regularization, such as ℓ 1 /ℓ 2 on the gradient (Wang et al, 2021(Wang et al, , 2022Wu et al, 2022a), ℓ p , 0 < p < 1, on the gradient (Hintermüller and Wu, 2013;Li Y. et al, 2020;Wu et al, 2021b), and transformed total variation (Huo et al, 2022), as alternatives to AITV. On the other hand, we can develop AITV variants of weighted TV or adaptive TV (Wu et al, 2021a; Zhang et al, 2022).…”
