Moreover, in one or more embodiments, the disclosed systems and methods utilize the cleaning confidence map as a reflection of how aggressively to modify digital images. In particular, in one or more embodiments, the disclosed systems and methods utilize the cleaning confidence map to remove shadows, identify and clean background pixels, and correct contrast in relation to the digital image.

An image processing apparatus includes a controller configured to perform: acquiring objective image data, the objective image data being generated by optically reading a manuscript and representing an objective image including a character image indicating a character; determining whether any condition, among conditions including first and second conditions, is satisfied; if the first condition is satisfied, transmitting, to a predetermined communication apparatus, first image data based on the objective image data, the first image data representing the objective image, receiving first processed data from the predetermined communication apparatus; and if the second condition is satisfied, executing, for the objective image data, a predetermined compression processing for reducing size of data representing the character image in the objective image data so as to generate second image data; transmitting the second image data to the predetermined communication apparatus; and receiving second processed data from the predetermined communication apparatus.

A method, non-transitory computer readable medium and apparatus for generating an output image are disclosed. For example, the method includes receiving an image, applying a first filter, applying a second filter, calculating a difference between the image with the second filter that was applied and the image with the first filter that was applied and transmitting the difference to a sharpening module and a segmentation module to generate the output image.

A system prints a document by generating a device-dependent font that is appropriate for the document and the print device. The system does this by identifying a font for the document, identifying an affine transformation matrix for the font, using the device resolution and current page location of the print device to modify the affine transformation matrix to yield a current transformation matrix, adding a reverse of the current transformation matrix to the affine transformation matrix to yield a modified font matrix, and generate a print file using the modified font matrix. The print device then uses the print file print the document with a font corresponding to the modified font matrix.

An image forming apparatus includes: a raster image processing unit configured to convert original image data into image data for image formation being of a raster image; an image forming unit configured to form an image on a paper sheet; a reading unit configured to generate read image data by reading the image formed on the paper sheet; a monitor setting unit configured to set a monitor setting color and an ideal value for the monitor setting color; a color tone monitoring unit configured to monitor a color tone difference between a value of the read image data in the monitor setting color and the ideal value; and a hardware processor configured to perform control to have color correction performed in the image forming unit, wherein the monitor setting color includes at least one of a primary color, a secondary color, a tertiary color, and a tertiary achromatic color.

Systems and methods for extracting text from images rendered on a display screen, the method comprising capturing a color image rendered on a display screen; and transforming the color image to binary color image, preserving text-like graphic components and filtering out non-text-like graphical components. The transforming comprises scanning one or more areas of the color image; and detecting continuous bi-tonal regions in the scanned one or more areas, wherein the continuous bi-tonal regions have large variances.

A document type recognition apparatus includes an image region separation unit, a smoothing unit, an edge enhancement unit, a histogram creation unit, and a document type recognition unit. The image region separation unit outputs a signal indicative of each region obtained by separating an input image into a character region and a pattern region. The smoothing unit performs smoothing processing to remove halftone dots of a particular number of lines or greater in the pattern region of the input image. The edge enhancement unit outputs an image subjected to edge enhancement processing depending on an amount of edge on an edge portion of the character region in the input image subjected to the smoothing processing. The histogram creation unit creates a histogram of the image subjected to the edge enhancement processing. The document type recognition unit recognizes a document type of the input image by utilizing the histogram.

An image processing apparatus includes a memory and at least one processor or circuitry or a combination thereof. The memory is configured to store determination conditions. The at least one processor or circuitry or the combination thereof is configured to acquire image data and extract a feature element from the image data. The at least one processor or circuitry or the combination thereof is further configured to determine whether the extracted feature element satisfies conditions defined in the determination conditions. The at least one processor or circuitry or the combination thereof is further configured to set an area with reference to an extracted feature element satisfying the conditions based on the determination conditions. The at least one processor or circuitry or the combination thereof is further configured to set an attribute of the area based on the determination conditions.

According to one embodiment, a computer-implemented method includes: capturing an image of a document using a camera of a mobile device; performing optical character recognition (OCR) on the image of the document; extracting an identifier of the document from the image based at least in part on the OCR; comparing the identifier with content from one or more reference data sources, wherein the content from the one or more reference data sources comprises global address information; and determining whether the identifier is valid based at least in part on the comparison. The method may optionally include normalizing the extracted identifier, retrieving additional geographic information, correcting OCR errors, etc. based on comparing extracted information with reference content. Corresponding systems and computer program products are also disclosed.
