摘要： An N95 mask air filter state detection device. The device can be integrated or attached to the N95 mask and includes an electrical sensor coupled to the air filter. The sensor detects static electrical or charge levels of the air filter and provides the electrical level values to a single chip microcomputer. The microcomputer, upon detecting values less than a preconfigured threshold, provides a signal to an LED to illuminate, to a buzzer to play an alert, and/or to a remote paired electronic device. The visual and audible alerts indicate the need to change the filter and thus prevent individuals from using non-functional masks. The alerts also prevent individuals from throwing away functional masks as non-emitting LED and silent buzzer indicate functional filter.

摘要： Disclosed herein are a method and an image processing apparatus implementing the method for color pixel counting in documents by integrating color detection and counting. The method determines if pixels are neutral (e.g., gray) or non-neutral (i.e., color). Windows are used to analyze the pixels. For each window, a number of pixels with at least one color plane ON are counted, as well as a number of ON pixels in each color plane. The windows are determined to be neutral or color. A billable count of color pixels is determined based on the neutrality of the windows. Based on the billable count of color pixels, a bill for outputting the document is determined.

摘要： Embodiments relate to systems and methods for dynamic sharpness control in system using binary to continuous tone conversion. Image data can be processed in the image path of a copier, printer, or other device to enhance sharpness based on user settings. The image can originate in a high-resolution and/or high-color format. The user can select sharpness values to provide better rendered detail. A front-end high-pass 2D filter can be adjusted in response to the settings. A binarized version of the image data is produced in the downstream path. At the back of the image path, the image would conventionally be sent through a binary data to extended contone (BDEC) low-pass filter, set to a fixed level, to produce contone output, counteracting the user's sharpness settings. Instead of applying a fixed back-end filter, that stage can be dynamically adjusted to correspond to the user's sharpness settings, reducing the low-pass effect proportionately.

摘要： The present disclosure relates to a method and system for processing isolated holes in an image to be printed or displayed. The method includes detecting whether pixels corresponding to an isolated hole in the image are in an off state, determining a sum of pixels that are in an on state in a first pixel ring surrounding the pixels corresponding to the isolated hole when the one or more pixels in the isolated hole are detected to be in the off state, comparing the sum of pixels in the pixel ring that are in the on state with a threshold sum, turning off a number of pixels in at least another pixel ring either comprising of or surrounding the pixels when the first sum of pixels in the on state is greater than the threshold sum, and outputting the isolated hole including the turned off first number of pixels.

摘要： A system calculates appropriate billing within an imaging pipeline. An input component receives an image that is described as a plurality of pixels. A PDL component receives the image and determines a location, a color and a designation for each of the one or more pixels. A marking engine modifies the one or more pixels based at least in part on the location and the color provided by the PDL component and places each of the one or more pixels as a monochrome or a composite pixel on a substrate. An analysis component counts the number of monochrome and composite pixels placed on the substrate by the marking engine, the number of composite pixels that include a designation are counted as monochrome. A billing component calculates the cost for placing each of the monochrome and the composite pixels counted by the analysis component.

摘要： A methodology for thin line detection and enhancement in electronic images is disclosed. The methodology includes associating an electronic image with at least one basic context window that is less than the size of the electronic image based on the input image resolution of the electronic image; detecting one or more predefined patterns which correspond to thin lines in the electronic image using the at least one basic context window; excluding patterns for the one or more detected patterns which are halftone patterns; and adding at least one pixel to the electronic image based on at least one of the remaining patterns so as to enhance thin line features in the electronic image. In some implementation, the methodology may be configured to handle electronic images having different resolutions. A system for thin line detection and enhancement in electronic images having different resolutions is also disclosed.
