Research and testing of image quality impairment evaluation methods for digi-tal watermarking in film videos
摘要
Abstract
Digital video watermarking has been widely adopted in the industry as an effective technical means to trace pi-rated recordings of films.However,a unified evaluation system for assessing the image quality impairment caused by digi-tal video watermarks in actual viewing environments has not yet been established.To address this research gap,this pa-per proposes an image quality impairment evaluation method that integrates subjective assessments with multi-dimen-sional objective image quality impairment analysis,incorporating different viewing scenarios such as DLP projection cin-ema,HDTV and LED cinema display.The research results demonstrate that this method can comprehensively evaluate the invisibility and degree of image quality impairment caused by digital video watermarking,thereby providing technical support for the development,testing,and application of core digital film image processing technologies,including digital video watermarking and image codecs.关键词
