Sacha Lewin

I am a Belgian Ph.D. student in data science and engineering at ULiège.

I am notably interested in NeRFs (see Nerfstudio).

I was an intern at EVS Broadcast Equipment where I worked on dynamic NeRFs for my master's thesis.

Previously, I was known for various plugins on Minecraft under the username "iSach" that I still partly use, including UltraCosmetics.

Considering the lack of existing public solutions and data for dynamic reconstruction of soccer scenes, we explore the use of the recent neural radiance fields (NeRFs) to tackle this challenging and specific task.

blind-date Video Neural Style Transfer: Stylizing videos using CNNs and an image translation network.
Sacha Lewin, Florian Delcour (2022)
Class Project
Deep Learning class @ ULiège (INFO8010)

Using pre-trained CNNs like VGG-19 and an image translation network, we can apply consistent neural style transfer on videos. This project was done in the Deep Learning class at ULiège. The project was graded 19/20 and best of the year.

Over 300k downloads

Ultra Cosmetics is my largest standalone project, started at 15 years old. It allows servers to be monetized without breaking Mojang's EULA, all for free with a large open-source community.

The project was taken over by Datatags, thanks to him!
