Soundwich: Video Generation with Layered and Controllable Audio
Zhuo Ning, AmirHossein Naghi Razlighi, Sagi Polaczek +2
Recent joint audio-video generative models can synthesize realistic videos with synchronized sound, but typically generate audio as a single mixed track. This limits source-level c…
Sound Sparks Motion: Audio and Text Tuning for Video Editing
AmirHossein Naghi Razlighi, Aryan Mikaeili, Ali Mahdavi-Amiri +2
Motion-centric video editing remains difficult for large generative video models, which often respond well to appearance changes but struggle to produce specific, localized actions…
Confident Splatting: Confidence-Based Compression of 3D Gaussian Splatting via Learnable Beta Distributions
AmirHossein Naghi Razlighi, Elaheh Badali Golezani, Shohreh Kasaei
3D Gaussian Splatting enables high-quality real-time rendering but often produces millions of splats, resulting in excessive storage and computational overhead. We propose a novel…
Neural 4D Evolution under Large Topological Changes from 2D Images
AmirHossein Naghi Razlighi, Tiago Novello, Asen Nachkov +2
In the literature, it has been shown that the evolution of the known explicit 3D surface to the target one can be learned from 2D images using the instantaneous flow field, where t…
