摘要： A method for determining parking availability includes receiving video data from a sequence of frames taken from an image capture device that is monitoring a parking area. The method includes determining background and foreground images in an initial frame of the sequence of frames. The method further includes updating the background and foreground images in each of the sequence of frames following the initial frame. The method also includes determining a length of a parking space using the determined background and foreground images. The determining includes computing a pixel distance between a foreground image and one of an adjacent foreground image and an end of the parking area. The determining further includes mapping the pixel distance to an actual distance for estimating the length of the parking space.

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.

摘要： A grayscale two-dimensional barcode may be converted to a two-dimensional color barcode. The color barcode includes a set of sub-regions, and the cells in each sub-region exhibits a color pattern that corresponds to pattern of binary, grayscale cells. The two-dimensional color barcode may be decoded by comparing the pattern for each sub-region to a known grayscale pattern. The two-dimensional color barcode may be used for error correction by first decoding the barcode in grayscale form based on the luminance without reference to color, then decoding the barcode based on its color and comparing the results.

摘要： A method for removal of punched hole artifacts in digital images includes, for a scanned document page, deriving an original digital image that defines the page in terms of a plurality of input pixels. A reduced resolution bitonal image is generated from the original image. The method further includes providing for identifying of candidate punched hole artifacts in the reduced resolution bitonal image and providing for testing the candidate punched hole artifacts for at least one of shape, size, and location. Where a candidate punched hole artifact meets the at least one test, the method includes generating a modified image. This includes erasing the candidate punched hole artifact from the original digital image.

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 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.
摘要翻译：提供了一种方法和系统，用于根据混合光栅内容处理对扫描图像数据进行分割，以更有效地处理不均匀的颜色触摸对象。扫描的数据被分割为背景和前景层，其中前景层由诸如文本字符的多个对象组成。多个对象中的至少一个被识别为不均匀的颜色。将不均匀的颜色对象划分为预定大小的像素块的多个子对象。然后，子对象通过均匀的颜色聚类，并以二进制压缩算法编码为前景层段。不均匀的颜色子对象被替换为用背景层算法进行压缩处理，或者根据子对象内的多个像素的颜色进行处理以确定特定颜色。在这种情况下，可以根据前景层段算法将子对象压缩为所确定的颜色的颜色。
