Embodiment 1

[0017] The technical feature of this embodiment is to replace the same person in each of the 25 photos per second in the movie. The replacement process includes information analysis and feature extraction of the replaced person, information collection and feature extraction of the replaced person, and comparison. Three steps to replace:

[0018] (1) Information analysis and feature extraction of the replaced person: First, use conventional person tracking and detection techniques to locate, detect and segment the face of the designated person to be replaced in the original film and television video; then use conventional edge detection and segmentation The operator method extracts the feature points of the facial features of the replaced person; then uses conventional triangular geometric projection, classification, clustering and computer processing methods to access the direction angle, illumination, color and shadow features of the replaced person;

[0019] (2) Information colle...

Embodiment 2

[0022] This embodiment selects a real film and television work with a duration of 120 minutes. Randomly select a 3 minutes or edit a film clip as a sample, and select the role of the replaced character in the original film and television film without glasses, masks and decorations. The specific steps for character replacement are:

[0023] (1). First decompose the selected original film and television film into 25 digital photos per frame, and then use keying technology to extract the facial features of the replaced person in the digital photo, and then the replaced person Measure the size of the face, then measure the light on the face of the replaced person, and finally store the above results in the selected computer;

[0024] (2) A display with high-definition high-speed automatic camera function is set up in the studio for the replacement character, or a high-definition high-speed camera is set in the direction of the display, so that the replaced character can repeatedly watc...

Abstract

The invention belongs to the technical field of digital movie the TV play production and playing, relates to the technology for replacing figures in digital movies and TV plays, and in particular to a method for replacing movie and TV play figures. The method includes: performing positioning, detecting, segmenting and feature extracting on the face of a to-be-replaced figure, positioning and extracting the feature points of the five sense organs of the to-be-replaced figure at the same time, allowing a substitute to imitate the facial performance of the to-be-replaced figure and shooting the substitute, measuring, analyzing and then storing the shot contents, and using figure replacing computer software to perform one-by-one comparison of matching, scaling, light compensation and seamless smoothness and automatically replace the face of the to-be-replaced figure with the face of the substitute. The method is simple in design principle, advanced in used equipment, mature in technology, good in effect, vivid in figure replacing, fast in replacing and friendly in operating environment.

Description

Technical field: [0001] The invention belongs to the technical field of digital film and television production and playback, and relates to a process technology for replacing characters in digital film and television dramas, in particular to a method for replacing characters in film and television dramas. Background technique: [0002] At present, some well-known universities and research institutions at home and abroad have conducted preliminary research and exploration on automatic face replacement technology in videos, and have achieved some research results. The master thesis "Research on Automatic Character Transformation Technology in Video Image" by Liu Delong of Jilin University in 2007 and the master thesis "Research on Automatic Face Replacement in Image / Video" by Li Chuanxue of Beijing Institute of Technology in 2011 can be found in China. The research content of Liu Delong specifically involves the following aspects: First, the identification of facial feature regions...
