Substitute method of role head of digital TV. program

Abstract

The invention discloses a substitute method for a digital video program role head. The method inputs static digital image information or image digital type of role needed to be substituted into the computer or other image processing device uses arithmetic operation match to determine the role to be substituted to transfer the original static digital image information or image digital model into real digital image information and all arithmetic transfer parameter in middle head part of each frame in video image product of the role, thus the substitute for head image in substitute role in original image program by above mentioned head image of the substitute role according to the determined all arithmetic transfer parameter and the localizing parameter of the digital image or image digital model of the substituted and substitute roles and by using the arithmetic transfer matching arithmetic.

Description

Technical field [0001] The present invention relates to a method for replacing the head of a character in a digital video program, in particular to a two-dimensional plane that can only input multiple angles of the head of the character to be replaced into a computer or other image processing equipment according to the user's wishes. Or three-dimensional still digital image information or image digital model, you can use the pixel matching algorithm in the mathematical transformation matching algorithm, such as the critical point filter (English full name is Critical Point Filter, referred to as CPF) algorithm, to determine the original video program The character that can be replaced is transformed from the original still digital image or image digital model of the character's head to the mathematical transformation parameters of the actual image of the character's head in each frame of the video program, and then according to the mathematical transformation parameters of the ...

Problems solved by technology

[0002] As long as the current video program works are produced, the image information of the characters in the video program is difficult to change or cannot be changed at all. However, in some fields, for commercial or entertainment purposes, it is often necessary Replace the image information of the character with the image information of other object characters that the user likes, but there is no effective method in the prior art that can easily, quickly and accurately identify the characters in the video program. Replace the head image of the character, especially the accurate and corresponding replacement of the head image information of the character with action posture and facial expression
