摘要： Mean shift is a nonparametric estimator of density which has been applied to image and video segmentation. Traditional mean shift based segmentation uses a radially symmetric kernel to estimate local density, which is not optimal in view of the often structured nature of image and more particularly video data. The system and method of the invention employs an anisotropic kernel mean shift in which the shape, scale, and orientation of the kernels adapt to the local structure of the image or video. The anisotropic kernel is decomposed to provide handles for modifying the segmentation based on simple heuristics. Experimental results show that the anisotropic kernel mean shift outperforms the original mean shift on image and video segmentation in the following aspects: 1) it gets better results on general images and video in a smoothness sense; 2) the segmented results are more consistent with human visual saliency; and 3) the system and method is robust to initial parameters.
摘要翻译：平均偏移是已经应用于图像和视频分割的密度的非参数估计器。传统的基于平均移位的分割使用径向对称的核来估计局部密度，鉴于图像的经常结构化的特性，更特别是视频数据，这是非最优的。本发明的系统和方法采用各向异性核平均移位，其中内核的形状，尺度和取向适应于图像或视频的局部结构。各向异性核被分解以提供用于基于简单启发式修改分割的句柄。实验结果表明，各向异性核平均偏移在以下几个方面优于原始平均偏移图像和视频分割：1）在平滑度方面对一般图像和视频获得更好的结果; 2）分段结果与人类视觉显着性更为一致; 和3）系统和方法对初始参数是鲁棒的。

摘要： The techniques and mechanisms described herein are directed to a system for stylizing video, such as interactively transforming video to a cartoon-like style. Briefly stated, the techniques include determining a set of volumetric objects within a video, each volumetric object being a segment. Mean shift video segmentation may be used for this step. With that segmentation information, the technique further includes indicating on a limited number of keyframes of the video how segments should be merged into a semantic region. Finally, a contiguous volume is created by interpolating between keyframes by a mean shift constrained interpolation technique to propagate the semantic regions between keyframes.

摘要： A process and system for modeling, learning and synthesizing cursive handwriting in a user's personal handwriting style. The handwriting synthesis system and process described herein addresses the problem of learning the personal handwriting style of a user based on limited handwriting samples and producing novel scripts of the same style. The handwriting synthesis process includes segmenting handwriting samples into individual characters using a two-level writer-independent segmentation process, aligning samples of the same character into a common coordinate frame, and learning and modeling the individual character. Synthesis of handwriting is performed by generating individual letters from the models and concatenating the letters using a conditional sampling algorithm. The result is a smooth and fluid connection between letters that successfully mimics the personal handwriting style of a user.

摘要： A real-time low frame-rate video compression system and method that allows the user to perform face-to-face communication through an extremely low bandwidth network. At the encoder side, the system is able to automatically select only a few good faces from the original sequence with high visual quality and compress and transmit them. At the decoder side, the system use image-morphing based rendering method to generate a normal frame-rate video. Experimental results show that the system is superior to more traditional video codecs for low bit-rate face-to-face communication.

摘要： An automated face enhancement system and process which can automatically improve faces in videos or other images by applying cosmetic effects, given only a small amount of user interaction for initialization. For an input video, the system will first track the face and eye locations, and classify pixels in the face into different facial components based on local color models. The classification results of different frames are temporally smoothed to ensure temporal coherence. A set of cosmetic filters are then applied to different facial components.
