New video amplification technique FrAM reduces noise while enhancing motion

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new video amplification technique called FrAM (Fractional-order Adaptive Motion Magnification). This method improves upon existing Eulerian video amplification by using a fractional-order Grünwald--Letnikov derivative and a per-pixel adaptive gain based on local signal reliability. FrAM effectively amplifies subtle motions while significantly reducing noise amplification, particularly in textureless regions, and can operate in real-time. AI

    Fractional-Order Adaptive Motion Magnification: Phase-Reliability Weighting for Noise-Constrained Video Amplification

    arXiv:2609.04502v1 Announce Type: cross Abstract: Eulerian video amplification boosts sub-pixel motion by band-pass filtering per-pixel intensity traces and applying a uniform gain. That gain ignores local structure, so sensor noise is amplified together with the signal, especial…
