    • A system, including a computer system running image processing software, receives an identification of a desired area to be imaged and collected into an oblique-mosaic image. The computer system creates a mathematical model of a virtual camera having a sensor higher in elevation from which the source oblique images were captured and looking down at an oblique angle, the mathematical model having an oblique-mosaic pixel map for the sensor of the desired area encompassing multiple source images. The computer system assigns a surface location to each pixel included in the oblique-mosaic pixel map and selects source oblique images of the geographic coordinates captured at an oblique angle and compass direction similar to the oblique angle and compass direction of the virtual camera. The computer system reprojects at least one source oblique image pixel of the area to be imaged for each pixel included in the oblique-mosaic pixel map to create the oblique-mosaic image.

    • A method for automatically steering mosaic cut lines along preferred routes to form an output mosaic image includes the step of creating an assignment map corresponding to the output mosaic image where each pixel has an initial designation of unassigned. Then, each pixel of the assignment map that intersects the preferred routes is marked as being a Preferred Cut Line pixel to divide the Assignment Map into one or more regions. For each region, a search is conducted to locate one or more source images that completely cover that region. If multiple source images completely covering the region are located, the method uses a Selection Heuristic to determine quality of coverage, and then designates each pixel in that region as being assigned to the source image determined to be best by the Selection Heuristic. For any remaining unassigned regions, the method searches for two or more source images whose combined footprint completely covers the region, and for each set of two or more combined images, a Pairing Heuristic is used for determining quality of coverage. Each pixel in the region is designated as being assigned to the two or more combined images determined best by the Pairing Heuristic. Then, the Preferred Cut Line pixels are redesignated to match the image assignments of their bounded regions, and the output mosaic image is formed by contributing pixel values from the source images based upon the designations set forth in the assignment map.
    • 用于沿优选路线自动转向马赛克切割线以形成输出马赛克图像的方法包括创建对应于输出马赛克图像的分配图,其中每个像素具有未分配的初始指定的步骤。 然后,与优选路线相交的分配图的每个像素被标记为优先切割线像素,以将分配图划分成一个或多个区域。 对于每个区域,进行搜索以定位完全覆盖该区域的一个或多个源图像。 如果定位完全覆盖区域的多个源图像,则该方法使用选择启发式来确定覆盖质量,然后将该区域中的每个像素指定为被选择启发式确定为最佳的源图像。 对于任何剩余的未分配区域,该方法搜索组合足迹完全覆盖该区域的两个或更多个源图像,并且对于每组两个或更多个组合图像,使用配对启发式来确定覆盖质量。 该区域中的每个像素被指定为分配给由配对启发式最佳确定的两个或多个组合图像。 然后,重新设计优选剪切线像素以匹配其有界区域的图像分配,并且通过基于分配映射中所阐述的指定从源图像中提供像素值来形成输出马赛克图像。

    • A method for creating an oblique-mosaic image from a plurality of source images is disclosed. Initially, a desired area to be imaged and collected into an oblique-mosaic image is identified and then a mathematical model of a sensor of a virtual camera is created, where the virtual camera has an elevation greater than an elevation of the area to be imaged. The mathematical model has an oblique-mosaic pixel map for the sensor of the desired area. A surface location is determined for each pixel included in the oblique mosaic pixel map, and at least one source oblique image pixel of the area to be imaged is reprojected for each pixel included in the oblique-mosaic pixel map to thereby create an oblique-mosaic image of the desired geographical area. The at least one single oblique-mosaic image is visually pleasing and geographically accurate. Further, techniques for compensating for building lean in oblique-mosaic images are disclosed.

    • A lead includes a conductor having a distal end and a proximal end and a resonant circuit connected to the conductor. The resonant circuit has a resonance frequency approximately equal to an excitation signal's frequency of a magnetic resonance imaging scanner or a resonance frequency not tuned to an excitation signal's frequency of a magnetic resonance imaging scanner so as to reduce the current flow through a tissue area, thereby reducing tissue damage. The resonant circuit may be included in an adapter that provides an electrical bridge between a lead a medical device such as an electrode, sensor, or signal generator. The resonant circuit may also be included directly in the housing of a medical device.
