摘要： A method and apparatus for reconstruction of a region of interest for an object is provided. The reconstruction of the object may be based on chords which may fill a part, all, or more than all of the region of interest. Using chords for reconstruction may allow for reducing data acquired and/or processing for reconstructing a substantially exact image of the ROI. Moreover, various methodologies may be used in reconstructing the image, such as backprojection-filtration, and modified filtration backprojection.

摘要： A method and apparatus for reconstruction of a region of interest (ROI) for an object using an imaging system is provided. The imaging system may substantially exactly reconstruct the ROI with a straight line trajectory. In the straight line trajectory, the ROI is not bounded or encircled by the actual trajectory of the source (e.g., no chords that are composed from two points on the source trajectory intersect or fill the ROI to be imaged). However, the ROI may be substantially reconstructed by using “virtual” chords to reconstruct the ROI. The virtual chords are such that no point on the trajectory is included in the virtual chord (such as one that is parallel to the straight line trajectory). These virtual chords may intersect and fill the ROI, thus enabling substantially exact reconstruction. Further, in reconstructing the image, the straight line trajectory may be assumed to be infinite in length.
摘要翻译：提供了一种用于使用成像系统重建用于对象的感兴趣区域（ROI）的方法和装置。成像系统可以用直线轨迹基本上精确地重建ROI。在直线轨迹中，ROI不受源的实际轨迹的限制或环绕（例如，由源轨迹上的两个点组成的和弦不相交或填充要被成像的ROI）。然而，可以通过使用“虚拟”和弦来重建ROI来实质地重建ROI。虚拟和弦使虚拟和弦中不包含轨迹上的点（例如平行于直线轨迹的点）。这些虚拟和弦可以相交并填充ROI，从而实现基本精确的重建。此外，在重建图像时，可以认为直线轨迹的长度是无限大的。

摘要： An exemplary method for online character recognition of characters includes acquiring time sequential, online ink data for a handwritten character, conditioning the ink data to produce conditioned ink data where the conditioned ink data includes information as to writing sequence of the handwritten character and extracting features from the conditioned ink data where the features include a tangent feature, a curvature feature, a local length feature, a connection point feature and an imaginary stroke feature. Such a method may determine neighborhoods for ink data and extract features for each neighborhood. An exemplary character recognition system may use various exemplary methods for training and character recognition.
