Embodiment Construction

[0052] The first embodiment provided by the present invention is a method for realizing organ animation, which utilizes ASM technology to obtain organ outlines in pictures or videos, and uses the acquired organ outlines to drive organ animation, and its implementation process is shown in Figure 1 ,include:

[0053] Step S101, using face detection technology to accurately locate the organ model in the picture or video.

[0054] Taking the face organ as an example, in step S101, at first obtain a static image or a video stream image containing a frontal face; then use face detection technology to find out the area of ​​the face from the acquired image;

[0055] Then perform feature point positioning: find the initial positions of several obvious feature points in the detected face area, such as the corners of the eyes and the corners of the mouth.

[0056] Step S102, searching the contour candidate points of the located organ model, and using the ASM technology to obtain the co...

Abstract

This invention discloses a realization organ animation methods and systems, its use of technology identified ASM organ profile, contour mapping and organ referred to the PCA model corresponding to the different state of the main characteristics of components, the corresponding projection value; then, in accordance with access to value-driven 3-D projection of organ motion parameters; referred to the use of organ-driven motion parameters campaign Thus, when the implementation of the present invention can drive mouth organ; addition of the invention described in the implementation of control points also can be identified the movement direction; use of organ-driven model of motion parameters, drivers mentioned above control points along the direction of movement sport, it can reflect mouth smile, anger, surprise and fear, and other expressions, therefore use this method to drive the mouth mouth can be shaped and coincide more closely with actual results.

Description

technical field [0001] The invention relates to the field of statistical data processing, in particular to the technology for realizing organ animation. Background technique [0002] ASM (Active Shape Model, active shape model) is a powerful object shape description method, which uses PCA (Principal Components Analysis, principal component analysis) technology to count shape features, and use the statistical shape features to study similar objects The change rule of the contour. [0003] At present, ASM technology is widely used in face contour positioning. When performing facial contour positioning based on ASM technology, the initial position of the facial organ contour is generally given first; then, near the initial position, the most suitable candidate points of the organ contour are searched, and the candidate points are organized into a new contour projection In the PCA space, a shape-constrained contour is obtained, and finally the final face organ contour can be p...
