摘要： As set forth herein, a computer-implemented method facilitates pre-analyzing an image and automatically suggesting to the user the most suitable regions within an image for text-based personalization. Image regions that are spatially smooth and regions with existing text (e.g. signage, banners, etc.) are primary candidates for personalization. This gives rise to two sets of corresponding algorithms: one for identifying smooth areas, and one for locating text regions. Smooth regions are found by dividing the image into blocks and applying an iterative combining strategy, and those regions satisfying certain spatial properties (e.g. size, position, shape of the boundary) are retained as promising candidates. In one embodiment, connected component analysis is performed on the image for locating text regions. Finally, based on the smooth and text regions found in the image, several alternative approaches are described herein to derive an overall metric for “suitability for personalization.”
摘要翻译：如本文所述，计算机实现的方法有助于预分析图像并且自动地向用户建议图像内的最合适的区域用于基于文本的个性化。具有空间平滑的图像区域和具有现有文本的区域（例如标牌，横幅等）是用于个性化的主要候选者。这产生了两组相应的算法：一种用于识别平滑区域，一种用于定位文本区域。通过将图像划分成块并应用迭代组合策略来找到平滑区域，并且满足某些空间属性（例如，边界的大小，位置，形状）的那些区域被保留为有希望的候选者。在一个实施例中，对用于定位文本区域的图像执行连接分量分析。最后，基于图像中发现的平滑和文本区域，本文描述了几种替代方法，以得出“适合个性化”的总体度量。

摘要： A method of defining a glyph font character representing an input binary code includes defining a first portion of a matrix using an input binary code including a plurality of input bits. A second portion of the matrix is defined by performing a transformation on the input binary code so that the second portion of the matrix includes a plurality of transformed bits. A glyph character is derived that corresponds to the matrix. The glyph character is defined by a plurality of components corresponding in location to said bits of said matrix, wherein the components of the glyph character comprise a first component (e.g. a forward slash /) that corresponds to and represents a “1” bit of the matrix and second component (e.g., a backslash \) that corresponds to and represents a “0” bit of the matrix. The transformation operation includes a NOT operation or other logic operation, and includes a shift operation. The transformation can be repeated to derive additional portions of the matrix by transforming the group of bits of the preceding matrix portion. The glyph characters corresponding to alphabet characters are each defined as a bitmap and are saved as Postscript Type 3 font.

摘要： A method and system is provided for segmenting scanned image data in accordance with mixed raster content processing for more efficient processing of non-uniform color touching objects. The scanned data is segmented to background and foreground layers wherein the foreground layer is comprised of a plurality of objects such as text characters. At least one of the plurality of objects is identified as being non-uniform in color. The non-uniform color object is partitioned into a plurality of sub-objects of predetermined size pixel blocks. The sub-objects are then clustered by uniform color and coded with a binary compression algorithm as a foreground layer segment. Non-uniform color sub-objects are alternatively discarded for compression with the background layer algorithm, or processed for determination of a particular color based upon the color of a plurality of pixels within the sub-object. In such a case, the sub-object can then be compressed in accordance with a foreground layer segment algorithm as the color of the determined color.

The base pattern is modulated via a user interface by adjusting positions of the pattern known for selectively controlling curve shapes of the pattern. A guilloché mark is illustrated by display on the imaging device of the adjusted base pattern and a compilation of associated replicate patterns for user assessment of the mark.

摘要： An image processing system such as a multi-function device (MFD) with an “e-reader” mode is disclosed. The e-reader mode can be activated by a user from the MFD user interface, or automatically detected by the system if the mode is set to “auto.” Once in e-reader mode, the system automatically locates the area corresponding to the e-reader screen, crops it, de-skews it when necessary, and enhances the image. In addition, N-Up (printing several pages of content on one physical page) may be applied if users desire. The enhancement adjusts background color, boosts the contrast, and de-blurs the image when necessary. Two embodiments of enhancement are presented. The first one performs Tone Reproduction Curve (TRC) adjustment and possible de-blurring on the entire screen area. The second one segments the screen area into three kinds of objects (text/picture/background). Different TRCs are applied to enhance the objects.
