摘要： An apparatus and a processor-implemented method are provided for determining a cusp within a stroke of electronic ink. Curvature at each of a plurality of points on the stroke is estimated. Based on the estimated curvature at each of the plurality of points, a neighborhood of the points where the cusp resides is identified. One of the points in the neighborhood of the points is determined to correspond to the cusp.

摘要： Methods and apparatus for displaying images, e.g., text characters, on display devices which have multiple separately controllable luminance elements per pixel. Multiple alpha values are generated per pixel, e.g., one per pixel sub-component. Filtering is then performed to generate a filtered alpha value for each pixel sub-component. The filtering operation uses as its input multiple alpha values. The alpha values used for the filtering operation may come from neighboring pixels. Accordingly, in the case where character glyphs are combined to form larger images, e.g., text strings, the filtering operation performed on glyph edge pixels depends on the content of a neighboring character glyph. In one embodiment unfiltered alpha values used to represent character glyphs are stored in a glyph cache. To avoid repeated filtering of character glyphs, in another embodiment, character glyphs are padded along their vertical edges, filtered and then stored in the glyph cache.
摘要翻译：用于在具有每个像素具有多个可单独控制的亮度元素的显示设备上显示图像（例如，文本字符）的方法和装置。每像素生成多个α值，例如每像素一个子分量。然后执行滤波以为每个像素子分量生成滤波的α值。过滤操作用作其输入多个α值。用于滤波操作的alpha值可能来自相邻像素。因此，在字符字形被组合以形成较大图像（例如文本串）的情况下，对字形边缘像素执行的滤波操作取决于相邻字符字形的内容。在一个实施例中，用于表示字符字形的未过滤的α值被存储在字形缓存中。为了避免字符字形的重复过滤，在另一个实施例中，字符字形沿其垂直边缘被填充，被过滤并存储在字形缓存中。

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 repainted.

摘要： The present invention relates to storing information including electronic ink. 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： A lasso select tool that allows a user to draw a flexible line of selection ink in order to select one or more graphical objects for manipulation. As the user draws this selection line, the lasso select tool continuously redraws and displays a connection line connecting one end of the selection line with the opposite end of the selection line. This connection line thus graphically demonstrates to the user the area that is presently encompassed by the resulting lasso enclosure. Further, the lasso select tool will change the appearance of any object selected with the lasso enclosure. The lasso select tool also selects objects that are only substantially encompassed by the lasso enclosure. For example, the lasso select tool may select ink objects that are only 60% or more encompassed by the lasso enclosure.

摘要： A method of analyzing electronic ink, in which document data for a document containing electronic ink content is received from a software application running on a first processing thread. The first processing thread is employed to provide the document data to an electronic ink analysis process for analyzing on a second processing thread. Control of the first processing thread is then returned to the software application. After the results of the analysis are received, the results are reconciled with the current document data for the document.

摘要： A method for enhancing a textual image for undergoing optical character recognition begins by receiving an image that includes native lines of text. A background line profile is determined which represents an average background intensity along the native lines in the image. Likewise, a foreground line profile is determined which represents an average foreground background intensity along the native lines in the image. The pixels in the image are assigned to either a background or foreground portion of the image based at least in part on the background line profile and the foreground line profile. The intensity of the pixels designated to the background portion of the image is adjusted to a maximum brightness so as to represent a portion of the image that does not include text.

摘要： A processing device may recognize a number of input handwritten strokes, which may represent a mathematical expression, a chemical formula, or other two-dimensional structure. Rewriting rules of a grammar may be applied to the strokes to produce a number of possible recognition results. Each of the possible recognition results has a respective score based on a sum of rewriting rules applied to the strokes to produce respective ones of the possible recognition results. Input may be provided to identify misrecognized strokes and a correct terminal production, or symbol corresponding to the misrecognized strokes. Strokes may be misrecognized for many reasons, including parsing errors, over-grouping or under-grouping of matrices, and improper placement of a recognized terminal production, or symbol, with respect to a root structure. Correction hints may be leveraged for correcting types of errors mentioned above.

摘要： A number of regions and partitions may be created based on input handwritten atoms and a grammar parsing framework. Productions for tabular structures may be added to the grammar parsing framework to produce an extended grammar parsing framework. Each of the regions may be searched for a tabular structure. Upon finding a tabular structure, a type of tabular structure may be determined. Configuration partitions may be created, based on the added productions, and added to the created partitions. A set of configuration regions may be created based on the configuration partitions and added to the created regions. The productions for tabular structures and productions of the grammar parsing framework may be applied, as rewriting rules, to the atoms to produce possible recognition results. A best recognition result may be determined and displayed. A mechanism for correcting misrecognition errors, which may occur while recognizing tabular structures, may be provided.
