This preprint studies non-line-of-sight (NLOS) imaging, aiming to reconstruct hidden objects in both “see-through-the-medium” and “see-around-the-corner” scenarios. Using a unified reconstruction framework that incorporates scale modulation and joint regularization terms, the authors report efficient recovery of both albedo and depth across diverse measurement settings, with improved reconstruction quality and high computational efficiency. The paper also introduces a new dataset spanning multiple measurement settings for both scenario categories. The authors explicitly note it is a preprint and not peer reviewed, and no competing interests are declared. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Abstract Non-line-of-sight (NLOS) imaging, which aims to reconstruct objects hidden from direct view, including see-through-the-medium and see-around-the-corner scenario categories, has become a promising field with broad applications. In this work, we introduce a unified NLOS reconstruction framework that addresses both categories of NLOS imaging problems. By incorporating scale modulation and joint regularization terms, the framework efficiently recovers albedo and depth across diverse measurement settings while enhancing reconstruction quality. To the best of our knowledge, this is the first method to deliver high-fidelity reconstruction with high computational efficiency across general NLOS imaging scenarios, providing a practical solution to real-world challenges. Moreover, we introduce a novel dataset that covers multiple measurement settings for both scenario categories, supporting future research in the field.
