Description: 实现一种结合颜色空间、变换及变形模板的自动唇部定位及唇轮廓提取、跟踪方法首先在空间建立肤色模型进行人脸检测、定位, 并由人脸几何特征进行唇部粗定位然后结合唇色模型进行变换使肤、唇色差别明显化, 提出根据亮度信息对变换结果预处理后用法进行图像分割, 经唇色模型进一步验证后实现唇部精定位再使用变形模板来进行嘴唇轮廓特征提取, 为增强内轮廓定位的鲁棒性, 对经亮度预处理和唇色模型验证得到的口腔区域边缘图进行曲线拟合来实现内轮廓定位最后, 将唇读图像序列中上一帧的唇部定位结果拓展后作为当前帧的预测区域再进行处理来实现唇动跟踪。-To achieve a combination of color space, transform and deformable template automatic lip localization and lip contour extraction, tracking the establishment of the first color model in the space of face detection, location, geometric features of the face by the rough location and then combined with lip lip transformation so that the skin color model, lip color difference visible, presented the results according to the luminance information to transform the image after pretreatment use of segmentation, and further validated by the lip model to achieve precise positioning and then use the deformation of the lip template for lip contour extraction , to enhance the robustness of location within the outline, by the brightness of the pretreatment and the lip model validation by oral Quyu edge map to fit curve to achieve the final positioning within the contour, the lip-reading image sequence in the last frame of the lips After positioning results extend the forecast area as the current frame Platform: |

Description: The book describes a range of deformable template models, from coarse sparse models involving discrete, fast computations to more finely detailed models based on continuum formulations, involving intensive optimization. Each model is defined in terms of a subset of points on a reference grid (the template), a set of admissible instantiations of these points (deformations), and a statistical model for the data given a particular instantiation of the object present in the image. A recurring theme is a coarse to fine approach to the solution of vision problems. The book provides detailed descriptions of the algorithms used as well as the code, and the software and data sets are available on the Web.

Description: 我们采用无办法变形质量人体模板的网格从其原来的姿势对点云数据指定不同的姿势。在此方法中,我们首先建立粗模板网格和点云通过压缩的光谱嵌入技术,利用人体四肢之间的对应关系。基于这些对应关系,我们定义使用弹性能量泛函的非刚性配准的目标和应用离散的梯度流,以减少粗控制网格和点云之间的区别。然后可从之后使用均值坐标控制网格的变形变形的模板网格。(We employ a deformable, deformable human body template mesh to specify different poses from its original pose to point cloud data. In this approach, we first build coarse template meshes and point clouds through compressed spectral embedding techniques that exploit the correspondence between human limbs. Based on these correspondences, we define the use of elastic energy functionals for nonrigid registration of targets and apply discrete gradient flows to reduce the difference between coarse control grids and point clouds. Thereafter, the template mesh can be controlled by using mean coordinates to control mesh deformation.) Platform: |
