BudgetPix, our recent work, allows you to adapt any pixel-space diffusion into budget-flexible inference. It saves you more than half of the computation cost without a quality drop (noticable by human eyes). Great work by @ozgurkara99 and the team.
1/8 BudgetPix: one model, any compute budget. Our pixel-space image generator adapts computation to image content at inference time. Same prompt, same noise, from 100% down to just 10% of the tokens. → Project Webpage: karaozgur.com/BudgetPix

We revisit the problem of video composition through the lens of GenAI.
🎥 Introducing Split-then-Merge: A new video composition framework! This approach enables the composition of any foreground video with any background video. Unlike conventional methods that rely on annotated datasets or handcrafted rules, Split-then-Merge (StM) splits a large unlabeled corpus of videos into dynamic foreground and background layers, then merges them to learn how dynamic subjects interact with diverse scenes. Work done in collaboration with team members at @Google: Du Tran (@dutran) , Yujia Chen (@IssacCyj) , Prof. Ming-Hsuan Yang (@MingHsuanYang), Vincent Chu: and my advisor at UIUC (@siebelschool): Prof. James M. Rehg (@RehgJim). I will be attending NeurIPS, San Diego and would be happy to chat more! 🔗Project Webpage: split-then-merge.github.io/ 📄Paper: arxiv.org/abs/2511.20809

This new problem setup is both interesting and challenging. It demands a crucial balance: preserving the object's identity while simultaneously achieving a seamless and harmonious overall composition.

Every year at @CVPRConf (and other conferences), a lot of money was spent on printing these posters (~150$ x 2500=375k), and after the conference, all these posters are trashed and wasted like these. A better business model should save costs here.
