Denoising Analysis Of Optical Response Noise Removal Non-Uniformity Filter In Camera Source Recognition

Abstract

Determining The Source Of The Creation Of Digital Content Is Considered One Of The Most Popular Open Questions In The Multimedia Forensics Community. So Far, Light Response Non-Uniform Noise Extraction (PRNU) Has Been Proposed As A Means Of Identifying Sensor Fingerprints. It Can Be Judged By Multiple Images Taken By The Same Camera Using The Noise Removal Filtering Process. A Noise Model Based On Signal Correlation Is Proposed And Compared With Other Commonly Used Models For This Purpose. The Technical Basis And Experimental Results Are Introduced And Discussed.
