Slides and abstract of my talk "Interferometric single-pixel imaging with a multicore fiber" made at ISCS23 (Luxembourg, June 12-14, 2023) now available at laurentjacques.gitlab.io/event and laurentjacques.gitlab.io/publi All this is based on the work of Olivier Leblanc. Long journal preprint version "Interferometric lensless imaging: rank-one projections of image frequencies with speckle illuminations" on arxiv.org /abs/2306.12698 in colaboration with S. Sivankutty, M. Hofer, H. Rigneault, (toot generated thanks to tootpick.org directly from my website

In February I gave a popular talk in the “Math encounters” series at MoMath, New York. My topic was the mathematics of X-ray tomography.

Try out my 5 levels of tomographic brain puzzles in YouTube: youtu.be/ahyUFO_3XB4

Let me know in the comments how many you were able to solve! 😃

Currently enjoying attending the Mathematical Models for Plug-and-play Image Restoration in Paris. Very interesting introductory tutorial talks by Samuel Hurault and Regev Cohen on PnP and RED in common framework built on potentials, convergence analysis and improvements gdr-mia.math.cnrs.fr/events/pn

@gabrielpeyre This is indeed a key experiment by Alan V. Oppenheim. Following his results, I realized with T. Feuillen, a few years ago, that this is also true in complex compressive sensing with Gaussian matrices. Paper, slides, demo, and video here:
