摘要： Disclosed herein is a method for detecting thin lines in image data. The method is performed by a processor to process contone image data. The processing includes thresholding a window of pixels established in the contone domain to generate a binary window of image data, and then determining characteristics associated with on pixels or runs of the binary data. The characteristics (start and end locations, length of on runs) are then thresholded. The processing in the contone and binary domain are used to determine if a thin line exists in the window of image data. The disclosed method produces better quality output images and reduces the addition of false lines in an image.

摘要： Disclosed herein is a method for detecting thin lines in image data. The method is performed by a processor to process contone image data. The processing includes thresholding a window of pixels using a first set of thresholds established in the contone domain, and then counting and thresholding the binary pixels using a second set of thresholds. The processing in the contone and binary domain are used to determine if a thin line exists and if a pixel of interest in the window is an edge pixel that is part of a thin line. The disclosed method produces better quality output images and reduces the addition of false lines in an image.

摘要： Disclosed herein is a method for detecting thin lines in image data. The method is performed by a processor to process contone image data. The processing includes combining a first result of thin line detection using a first method and a second result of thin line detection using a second method to produce an improved thin line determination in the image data. The methods include processing and thresholding in the contone and binary domain to determine if a thin line exists in the window of image data. The thin line determination may also be merged with the image data as processed using other image segmentation techniques. The disclosed method produces better quality output images and reduces the addition of false lines in an image.

摘要： A method and system are provided for reducing the bit depth of grayscale imagery using multi-bit halftoning. The halftoned image data may be lossy or losslessly compressed and stored in memory or transmitted over a communication channel. At the time of printing, the images are decompressed and reconstructed to a grayscale image data using Sigma filtering to preserve edges. Preferably, different Sigma filters may be applied based on contrast information within a local neighborhood region. Fuzzy edge detection may also be used to preserve edge features and prevent smearing.

摘要： The embodiments describe calculating and store scaling information based on processing input binary image data. By manipulating data that is received in binary format, the most cost effective method for scaling may be chosen. The input image data is scanned, a resolution (e.g., for display or output) is determined and a scaling method is determined. If the input binary image data needs to be scaled down to a smaller resolution, the binary image data is processed and scaled and then converted to grayscale image data. If the image data must be scaled to a larger resolution, the input binary image data is first converted to grayscale image data before processing using a segmentation tag-based scaling method. The scaled image data may then be output to an output device, such as a display, printer, or image output terminal.
摘要翻译：实施例描述了基于处理输入的二进制图像数据来计算和存储缩放信息。通过操纵以二进制格式接收的数据，可以选择最具成本效益的缩放方法。扫描输入图像数据，确定分辨率（例如，用于显示或输出），并且确定缩放方法。如果输入的二进制图像数据需要缩小到更小的分辨率，则处理和缩放二进制图像数据，然后将其转换为灰度图像数据。如果图像数据必须缩放到更大的分辨率，则在使用基于分段标签的缩放方法处理之前，首先将输入的二进制图像数据转换为灰度图像数据。然后，缩放的图像数据可以被输出到输出设备，诸如显示器，打印机或图像输出端子。

摘要： A method is described to match an original binary image with the dynamic range of a desired target document. The original binary image is restored first to contone and a histogram of the contone image is processed to generate a TRC for the contone image with improved dynamic range. The histogram processing includes determining a histogram of the contone image, and generating the TRC based on matching the determined histogram with a target histogram profile. This helps in matching outputs from legacy devices to a desired quality.
