Adaptive Coded Illumination Fourier Ptychography Microscopy Based On We introduce noise coded illumination (nci), a scene level intervention for helping detect spatiotemporal manipulations of video by coding the light in an environment with noise. In this paper, we show how coding very subtle, noise like modulations into the illumination of a scene can help combat this advantage by creating an information asymmetry that favors verification. our approach effectively adds a temporal watermark to any video recorded under coded illumination.
Noise Under D C Illumination Download Scientific Diagram We propose a new type of watermarking, which we call noise coded illumination (nci), that instead watermarks the illumination in a scene. our approach works by modulating the intensity of each light source by a subtle pseudo random pattern drawn from a distribution that resembles existing noise. The system, called noise coded illumination, programs subtle, nearly invisible fluctuations in light at events or locations, such as press conferences, that are captured by any camera. A team led by cornell university's asst. prof. abe davis has created just such a system, and it's known as "noise coded illumination" (nci). in a nutshell, nci involves adding a coded flicker. Their new method, "noise coded illumination" (nci), addresses those and other shortcomings by hiding watermarks in the apparent noise of light sources.

Vidnci implements the novel nci technique described in the research paper "noise coded illumination for forensic and photometric video analysis" (arxiv:2507.23002). this technique embeds unique, pseudo random noise codes into video illumination, providing a verifiable signature for detecting manipulations and ai generated content. The concept, called noise coded illumination, was presented august 10 at siggraph 2025 in vancouver, british columbia, by peter michael, a cornell computer science graduate student who led. Each watermarked light source has a secret code that can be used to check for the corresponding watermark in the video and reveal any malicious editing.
