Research and Application of LDA Model in Movies Images Based on the Visual Effects of Computer Images

Abstract

With the advent of the image age, the popularity of war-themed film and television dramas in the new century has promoted a new wave of thematic narratives. Facing the era of computer graphics, the main theme narrative adopts a series of new reconstruction strategies, namely: the spectacle strategy of visual expression, the typification strategy of narrative subjects, and the striation strategy of character modelling. As an important genre of Chinese movies, war-themed themed movies often focus on the education and dissemination of national ideology, but “The Eight Hundred” broke the stereotype of this type of movie to the audience. Taking the film “The Eight Hundred” as an example, using the LDA model of computer image characteristics, combined with the related theories of visual effects, the thesis explores how the main theme of contemporary warfare movie content is expressed through images and its unique image style.
