摘要： Embodiments of camera-based scanning are described. In various embodiments, scanned documents can be created using images captured by a camera associated with a device. An image captured by the camera is processed to identify portions within the image that correspond to rectangular objects such as paper, business cards, whiteboards, screens, and so forth. One or more of these portions can be selected for scanning automatically based on a scoring scheme and/or semi-automatically with the aid of input from a user. One or more scanned documents are created from the selected portions by un-warping the selected portions to remove effects of perspective (e.g., rectify the portions to rectangles) and applying various image enhancements to improve appearance.
摘要翻译：描述基于相机的扫描的实施例。在各种实施例中，可以使用与设备相关联的摄像机捕获的图像来创建扫描的文档。处理由相机拍摄的图像以识别图像中对应于矩形对象（例如纸张，名片，白板，屏幕等）的部分。可以选择这些部分中的一个或多个，以便借助于来自用户的输入，基于评分方案和/或半自动地自动扫描。通过使所选择的部分变形来去除所选部分中的一个或多个扫描文档，以去除透视效果（例如，将部分整理为矩形）并应用各种图像增强以改善外观。

摘要： In embodiments consistent with the subject matter of this disclosure, a user may input strokes as digital ink to a processing device. The processing device may partition the input strokes into multiple regions of strokes. A first recognizer and a second recognizer may score grammar objects included in regions and represented by chart entries. The scores may be converted to a converted score, which may have at least a near standard normal distribution. The processing device may present a recognition result based on highest converted scores according to a recurrence formula. The processing device may receive a correction hint with respect to misrecognized strokes and may add a penalty score with respect to chart entries representing grammar objects breaking the correction hint. Incremental recognition may be performed when a pause is detected during inputting of strokes.
摘要翻译：在与本公开的主题相一致的实施例中，用户可以将笔画作为数字墨水输入到处理设备。处理装置可以将输入笔划划分成多个笔画区域。第一识别器和第二识别器可以对包括在区域中的语法对象进行评分并由图表条目表示。得分可以转换成转换得分，其可以具有至少近标准正态分布。处理装置可以根据递归公式提供基于最高转换分数的识别结果。处理设备可以接收关于错误识别的笔画的校正提示，并且可以相对于表示打破校正提示的语法对象的图表条目添加惩罚分数。当在笔画输入期间检测到暂停时，可以执行增量识别。

摘要： In embodiments consistent with the subject matter of this disclosure, a user may input one or more strokes as digital ink to a processing device. The processing device may produce and present a recognition result, which may include a misrecognized portion. A user may indicate a desire to correct the misrecognized portion and may further select one or more strokes of the misrecognized portion. The processing device may then present the one or more recognition alternates corresponding to the selected one or more strokes of the misrecognized portion. In some embodiments, the processing device may permit a user to rewrite the selected one or more strokes of the misrecognized portion with newly entered digital ink. Features, such as, rewriting and correction of the input digital ink may be discoverable in some embodiments.
摘要翻译：在与本公开的主题相一致的实施例中，用户可以将一个或多个笔画作为数字墨水输入到处理设备。处理装置可以产生和呈现识别结果，其可以包括错误识别的部分。用户可以指示纠正错误识别的部分的愿望，并且可以进一步选择错误识别部分的一个或多个笔画。处理装置然后可以呈现对应于误识别部分的所选择的一个或多个笔画的一个或多个识别代替。在一些实施例中，处理设备可以允许用户使用新输入的数字墨水来重写错误识别部分中所选择的一个或多个笔画。在一些实施例中，可以发现诸如重写和校正输入数字墨水的特征。

摘要： Ink is stored in a data structure that includes a mapping of the ink's coordinates from one space to another. The responsibility of transforming the ink into desired coordinates occurs after the capture of the ink and at least based on the mapping in the data structure.

摘要： Ink is stored in a data structure that permits later retrieval by applications. The ink includes stroke information and property information. Properties may be associated globally with the ink strokes and/or with each stroke individually. Aspects include a data structure that supports ink for multiple applications. Using the storage system, method, and data structure, various applications may expand on ink to include additional attributes while permitting the ink to be used in applications not supporting the additional attributes. When encountering an unknown tag, the applications will skip past the end of the tag and its associated data to start reading the next tag.

摘要： Apparatus and methods for dynamically rendering digital ink strokes of arbitrary stroke width while a user is drawing the ink strokes. An ink rendering system may receive sampled pen tip positions associated with a stylus or pen on a digitizer. The ink rendering system may further determine pen tip instances having particular shapes, sizes, and/or rotations, and may determine connecting shapes, preferably quadrangles, that connect between the pen tip instances. Smoothing techniques may also be used for existing digital ink.

摘要： Apparatus and methods for dynamically rendering transparent ink strokes, in some situations such that the rendered ink stroke has transparency similar to physical ink while it is being drawn. For example, the ink stroke may be dynamically rendered as a stroke having uniform transparency while it is being drawn. Only the new ink segment that has most recently been added to the stroke may be drawn, and areas of the new ink segment that overlap older segments of the ink stroke may be frozen, or excluded from being re-painted.
