摘要： A method and apparatus for code communication is disclosed in order to achieve band-width compression. Successive portions of information are derived and the next portion of information is predicted from at least one preceding portion, an error signal is then generated corresponding to the difference between the predicted portion and the next actual portion of information, whereafter the error signal is coded for transmission to a receiving device. The system is particularly described for coding two level signals derived from a facsimile transmitter, e.g., by the scanning of text or pictures.

摘要： A system for compressing or compacting data that is representative of scanned images. Involved are predictive coding of two level pictorial data, followed by run-length coding characterized by an infinite overflow capability. The predictive stage utilizes an nth-order exhaustive, causal predictor which looks at adjacent points of previous lines and preceding points of present lines to predict what color (black or white) the predictive is. If the prediction is in error, a binary one is transmitted. Alternatively, if the prediction is correct, a binary zero is transmitted. The run-length coding is adapted to code the run-lengths of binary zero between binary one errors using a dual-base counting system, where p represents one base (the number of low order subword states) and n represents a second base (the number of high order subword states) with a subword length, L, of log2 (p + n) bits. Mutually exclusive states in this run-length counting system provide an automatic comma for separating variable-length words (groups of subwords). A significant advantage of this type of run-length number system is that it provides a practical run-length encoding technique with the flexibility of variable-length overflow. The overall data compacting system also achieves a relatively high compression ratio for line drawings and other related type printed matter.
摘要翻译：用于压缩或压缩表示扫描图像的数据的系统。涉及两级图像数据的预测编码，其次是以无限溢出能力为特征的游程长度编码。预测阶段利用第n级详尽的因果预测因子，它可以查看前一行的相邻点和当前行的先前点，以预测预测的颜色（黑色或白色）。如果预测错误，则发送二进制。或者，如果预测是正确的，则发送二进制零。游程长度编码适于使用双基计数系统对二进制一个错误之间的二进制零的游程进行编码，其中p表示一个基数（低位子字状态的数量），n表示第二个基数（具有log 2（p + n）位的子字长度L的高阶子字状态数。该运行长度计数系统中的互斥状态提供了用于分离可变长度字（子词组）的自动逗号。这种类型的游程长度数字系统的一个显着优点是它提供了具有可变长度溢出的灵活性的实际的游程编码技术。整体数据压缩系统还实现了线图和其他相关类型印刷品的相对较高的压缩比。

摘要： An obtaining unit obtains a plurality of first pixel values and a plurality of second pixel values generated by an image sensor and corresponding to a plurality of pixels. A first gain is applied to each of the plurality of first pixel values and a second gain greater than the first gain is applied to each of the plurality of second pixel values. An encoding unit encodes each of a plurality of target pixel values on the basis of a correlation with a reference pixel value corresponding to a same pixel among a plurality of reference pixel values. The plurality of target pixel is one of the plurality of first pixel values and the plurality of second pixel values, and the plurality of reference pixel values is the other of the plurality of first pixel values and the plurality of second pixel values.

摘要： A system for determining compression rates for images, the system comprising a processing resource configured to: obtain a given image at least partially comprising a given text; compress the given image at a given compression ratio, giving rise to a compressed image; perform Optical Character Recognition (OCR) on the compressed image, giving rise to OCR text; compare the OCR text to the given text, giving rise to comparison results; upon the comparison results meeting a rule, increase the given compression rate; and upon the compression results not meeting a rule, return to a previous compression rate, if any.

摘要： A picture data transmission method and device are disclosed in the present invention. The picture data transmission method comprises: recoding a first picture to be transmitted, by a picture data sending terminal, to obtain a second picture, wherein the file size of the second picture is smaller than that of the first picture, and a quality difference between the second picture and the first picture is less than a pre-set threshold; and selecting one of the first picture and the second picture according to quality values of the first picture and the second picture and sending the selected picture to a picture data receiving terminal. According to the present invention, pictures can be recoded to obtain pictures with a small amount of data for data transmission, without affecting the picture quality, thereby saving network resources and reducing storage pressure.
