METHOD AND APPARATUS FOR CHANGING LIP SHAPE AND OBTAINING LIP ANIMATION IN VOICE-DRIVEN ANIMATION

摘要

FIELD: information technology.SUBSTANCE: method for changing lip shape includes: obtaining audio signals and obtaining a proportional lip shape change value according to characteristics of the audio signals; obtaining an original lip shape model input by a user and generating lip shape change value according to the original lip shape model and the obtained proportional lip shape change value; generating a lip shape grid model set according to the obtained proportional lip shape change value and a preconfigured lip pronunciation model library. The method for changing lip shape in a voice-driven animation includes an obtaining module, a first generating module and a second generating module.EFFECT: simple algorithm of changing lip shape in voice-driven animation.16 cl, 8 dwg
