    • Architecture that guides the freeform drawing of objects by a user to enable the user to produce improved drawings without significant training. As the user draws, the architecture dynamically updates a relevant shadow image proximate (e.g., underlying) the user's strokes. The strokes overlay an evolving shadow image, which shadow image is suggestive of object contours that guide the user during the drawing process. Relevant edge images selected from a large database are automatically blended to construct the shadow image. As the user draws, the strokes are dynamically analyzed using an encoding of overlapping windows for fast matching with the database of images. A top ranked set of matching database edge images are aligned to the drawing, a set of spatially varying weights blend the edge images into the shadow image, and a scoring technique is employed to select the optimum shadow image for display.
    • 指导用户自由绘制对象的架构,以使用户能够在不进行重大培训的情况下生成改进的图纸。 当用户绘制时,体系结构动态地更新用户笔画的邻近(例如,底层)的相关阴影图像。 笔画覆盖了不断变化的阴影图像,阴影图像暗示着在绘图过程中引导用户的对象轮廓。 从大数据库中选择的相关边缘图像将自动混合以构建阴影图像。 当用户绘制时,使用重叠窗口的编码动态地分析笔画,以便与图像数据库快速匹配。 匹配数据库边缘图像的顶级排列集合与图形对齐,一组空间变化的权重将边缘图像混合到阴影图像中,并且使用评分技术来选择用于显示的最佳阴影图像。

    • Users with mobile computing devices author skywriting and submit them to a virtual skywriting service. A mobile computing device having wireless network access is configured to capture a digital image of a real world scene including sky. The image is captured while the mobile computing device is in a geographical location or area. While the mobile computing device is still in the geographical location or area, it transmits via the wireless network a request for virtual skywriting. The request is received by a skywriting service that obtains or determines the geographical location/area that the computing device is in or near. The skywriting service selects a skywriting from among the previously submitted skywritings; the skywriting may be selected based on its having been entered at or associated with the geographical location. The mobile device receives the virtual skywriting from the service and displays a version of the digital image with the virtual skywriting added to the sky in the version of the digital image. Either the service or the mobile device may render the skywriting onto the image. Various effects may be applied in rendering the skywriting to give it realistic or vapor-like appearance.
    • 使用移动计算设备的用户可以创作并将其提交给虚拟的Skywriting服务。 具有无线网络访问的移动计算设备被配置为捕获包括天空的真实世界场景的数字图像。 当移动计算设备处于地理位置或区域时,捕获图像。 当移动计算设备仍处于地理位置或区域时,它通过无线网络发送虚拟天空写入请求。 该请求由获取或确定计算设备处于或接近的地理位置/区域的天空写入服务接收。 Skywriting服务从之前提交的空头作品中选择一个天空的文字; 可以基于其已经在地理位置输入或与其相关联来选择空格。 移动设备从服务接收虚拟天空写入,并且在数字图像的版本中显示添加到天空的虚拟天空的数字图像的版本。 服务或移动设备可以将图案呈现在图像上。 各种各样的效果可以用于渲染这个写真,使之成为现实的或类似蒸气的外观。

    • A technology is described for generating a strip panorama. The method can include selecting panoramas grouped together for a road to combine into the strip panorama. Side view images can be extracted from the plurality of panoramas. Another operation is computing depth maps for side view images using stereo matching. Depth histograms can be generated for depth map columns of the depth maps. The depth histograms can have column-depth alignment scores computed by multiplying corresponding depth values from at least two related depth histogram maps. A further operation can be aligning related side view images using the column-depth alignment scores. The aligned side view images can be stitched while maximizing a stitching score.
    • 描述了一种用于生成条带全景的技术。 该方法可以包括选择全部组合在一起的道路,以组合成条带全景。 可以从多个全景图中提取侧视图。 另一个操作是使用立体匹配来计算侧视图的深度图。 可以为深度图的深度图列生成深度直方图。 深度直方图可以通过将至少两个相关深度直方图的相应深度值相乘来计算列深度对齐分数。 进一步的操作可以使用列深度对准分数对准相关侧视图。 对齐的侧视图可以缝合,同时最大化拼接分数。

    • An integrally formed high density ceramic pellet, for use in a ballistic armor plate, has a longitudinally extending body portion and an impact receiving end face. The impact receiving end face includes an impact receiving proximal segment that is convexly curved and a distal segment that merges with a top surface of the body portion. The distal segment has lateral surfaces that have a region including at least a portion which is concave in configuration or a region including a substantially smooth angled configuration. A cross-sectional area of the distal segment at the area of merger is greater than a cross-sectional area taken across a nominally designated base of the proximal segment. The length of the contour line of the outer surface of the distal segment is between 5 and 25% of that of the entire integrally formed impact receiving end face.

    • An “Oblique Image Stitcher” provides a technique for constructing a photorealistic oblique view from a set of input images representing a series of partially overlapping views of a scene. The Oblique Image Stitcher first projects each input image onto a geometric proxy of the scene and renders the images from a desired viewpoint. Once the images have been projected onto the geometric proxy, the rendered images are evaluated to identify optimum seams along which the various images are to be blended. Once the optimum seams are selected, the images are remapped relative to those seams by leaving the mapping unchanged at the seams and interpolating a smooth mapping between the seams. The remapped images are then composited to construct the final mosaiced oblique view of the scene. The result is a mosaic image constructed by warping the input images in a photorealistic manner which agrees at seams between images.
    • “倾斜图像拼接器”提供了一种用于从表示场景的一系列部分重叠视图的一组输入图像中构造逼真倾斜视图的技术。 倾斜图像拼接器首先将每个输入图像投影到场景的几何代理上,并从期望的角度呈现图像。 一旦将图像投影到几何代理上,则对所渲染的图像进行评估,以确定要混合各种图像的最佳接缝。 一旦选择最佳接缝,通过在接缝处保持不变,并在接缝之间插入平滑的映射,相对于那些接缝重新映射图像。 然后将重新映射的图像合成以构建场景的最终镶嵌斜视图。 结果是通过以照片写实的方式扭曲输入图像构成的马赛克图像,其在图像之间的接缝处一致。
