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： A system and method for compressing digital pen stroke data utilizing curve simplification. Digital pen stroke images (ink images) generate a relatively large amount of data to preserve the ink image generated on a device. Current ink compression algorithms utilize lossless compression algorithm that have limited success. The invention provides a lossy compression algorithm to reduce the amount of data required to store and transmit ink data. The invention utilizes a two-part algorithm to reduce and compress the number of data points representing the ink data. The invention also utilizes curve splines to reconstruct and smooth the lossy ink data image.

摘要： This invention is directed toward a system and method for scanning a scene or object such as a whiteboard, paper document or similar item. More specifically, the invention is directed toward a system and method for obtaining a high-resolution image of a whiteboard or other object with a low-resolution camera. The system and method of the invention captures either a set of snapshots with overlap or a continuous video sequence, and then stitches them automatically into a single high-resolution image. The stitched image can finally be exported to other image processing systems and methods for further enhancement.

摘要： Knitwear modeling is disclosed. A macrostructure corresponding to a three-dimensional object is generated, based on a stitch pattern and optionally a color pattern. Yarn microstructure is generated and applied to the macrostructure to yield a knitwear model. The stitch positions of the macrostructure can be perturbed to achieve stitch position irregularities. The fluffiness of the yarn microstructure can be controlled. In an alternative embodiment, a two-dimensional knitwear texture is generated, which can then be mapped to a three-dimensional object to yield a knitwear model.

摘要： A computer-implemented mechanism for comparing information sets is described. The mechanism may include a comparison system that concentrates on the schema in each information set. An alternative embodiment includes an equality comparison mechanism that performs sets of initial comparisons to determine whether the information sets are inherently different and not needing a detailed comparison using the schema-centric comparison technique.

摘要： A system and method for optimizing the performance of a graphics intensive software program for graphics acceleration hardware. This system and method encompasses a procedure that validates the different functions of a 3D acceleration capable video card, decides whether to use the acceleration hardware and optimizes the software application to selectively use the functions that work on the specific video acceleration card. Functions checked include sub-pixel positioning, opacity, color replacement and fog. If these tests are successful, then the graphics acceleration is used by the software application. However, if the tests are not successful the decision is made not to use graphics accelerator. Those with ordinary skill in the art will realize that it is not necessary to perform all of the tests in a specific order. Additionally, other types of tests could be performed to ensure software application and video card compatibility before the software application is uses graphics acceleration to render 3D graphics.

摘要： A system and method for graphically showing the animation order of animated elements in a presentation program or other software. The invention consists of a User Interface (UI) widget which shows the order of the animation in the presentation. This UI employs an animation On Object User Interface (OOUI), or animation tag, that is preferably a rectangular control that encloses a number, and labels the order in which objects are animated. Each animation OOUI or animation tag is associated with an object on a display during creation and editing. The animation OOUI or tag is preferably placed in close proximity to the object it is associated with, rather than in a separate window or dialog box, and is hence termed ‘On Object’. The animation tag is active and responds to computer input device selection actions. Each animation OOUI is typically associated with an animation list.

摘要： A User Interface (UI) for a real-time panoramic image correction system and method that simplifies the use of the system for the user. The UI includes a control panel that allows a user to enter meeting table size and shape, camera position and orientation, and the amount of normalization desired (e.g. 0 to 100%). A window can also be implemented on a display that displays the corrected panoramic image. In this window, the head (either normalized or non-normalized) of a meeting participant, preferably one that is speaking, is extracted and displayed in a separate window. Additionally, the corrected panoramic image, whose size will vary in conjunction with the amount of warping applied, can be displayed and transmitted with extra pixels around its perimeter in order to allow the corrected or normalized panoramic image to adapt to any of the standard display size and resolutions and to simplify network transmission. The corrected image can also be transmitted with standard resolutions using non-unity pixel aspect ratios to simply network transmission.

摘要： Generation, coding and transmission of an effective video form, scalable portrait video. As an expansion to bi-level video, portrait video is composed of more gray levels, and therefore possesses higher visual quality while it maintains a low bit rate and low computational costs. Portrait video is a scalable video in that each video with a higher level always contains all the information of the video with a lower level. The bandwidths of 2–4 level portrait videos fit into the bandwidth range of 20–40 Kbps that GPRS and CDMA 1X can stably provide. Therefore, portrait video is very promising for video broadcast and communication on 2.5 G wireless networks. With portrait video technology, this system and method is the first to enable two-way video conferencing on Pocket PCs and Handheld PCs.
