摘要： Disclosed are methods and apparatus for processing linguistic expressions (e.g., opinionated text documents). The linguistic expressions are processed by, firstly, detecting topics of interest discussed in the linguistic expressions. The sentiment, or sentiments, of an originator with respect to each of the topics detected in the linguistic expressions is then assessed. The originators are then grouped (or clustered) into one or more groups based on the similarities between the originators' respective sets of detected topics and corresponding sentiments. Semantic information is then associated with a given group. Finally, for a given member of a given group, a profile is created or updated. This profile comprises attributes that may be based on a degree of membership of the given member to the given group and the semantic information associated with the given group.

摘要： Disclosed is a method for scanning and processing an image using the error diffusion screening technology, comprising: (1) scanning each pixel Mi of an nth line in an original image one by one and then storing a scanning result of the pixel Mi to an ith storage location; and (2) processing the stored result of the pixel Mi by using error diffusion and scanning pixels of an n+1th line in the original image until all pixels of the nth line have been processed and all pixels in the n+1th line have been scanned and stored, wherein once processing for the pixel Mi is completed, a scanning result of a pixel of the n+1th line is stored to the ith storage location previously occupied by the pixel Mi. Based on the method, the capacity for storing is only required to be able to store the data of one line in an image in the scanning direction, which saves the storage for bidirectional scanning. The method can optimize the hardware used to implement error diffusion and improve the operating efficiency. Also disclosed is a system for achieving the method.
摘要翻译：公开了一种使用误差扩散筛选技术对图像进行扫描和处理的方法，包括：（1）逐个扫描原始图像中的第n行的每个像素Mi，然后将像素Mi的扫描结果存储到第i个存储位置; 和（2）通过使用原始图像中的第n + 1行的误差扩散和扫描像素来处理像素Mi的存储结果，直到第n行的所有像素都被处理并且第n + 1行中的所有像素已被扫描并存储，其中一旦针对像素Mi的处理完成，将第n + 1行的像素的扫描结果存储到先前由像素Mi占据的第i个存储位置。基于该方法，存储容量只需要能够将扫描方向上的一行数据存储在图像中，从而节省用于双向扫描的存储。该方法可以优化用于实现误差扩散的硬件，提高运行效率。还公开了一种用于实现该方法的系统。

摘要： The present invention discloses a full parallax three-dimensional display device. It comprises a projector array and an orthogonal cylinder raster screen. The orthogonal cylinder raster screen comprises the first cylinder raster and the second cylinder raster. The projector array and the orthogonal cylinder raster screen are put in order. The projector array projects images on the orthogonal cylinder raster screen. The raster directions of the first cylinder raster and the second cylinder raster of the orthogonal cylinder raster screen are parallel to the x-axis and the y-axis, respectively. The advantage of the present invention is that it can generate 3D images of high image resolution and high view-field resolution. The extremely tiny view field intervals can bring completely continuous and jumping-free 3D perception for the viewer, reduce the fatigue caused by discontinuous view field in conventional 3D display, and achieve full parallax 3D display including horizontal parallax and vertical parallax.
