  • Patent number: 10713544
    Abstract: Image data is run through a neural network, and the neural network produces a vector representation of the image data. Random sparse sampling masks are created. The vector representation of the image data is masked with each of the random sparse sampling masks, the masking generating corresponding sparsely sampled vectors. The sparsely sampled vectors are transmitted to nodes of a consensus network, wherein a sparsely sampled vector of the sparsely sampled vectors is transmitted to a node of the consensus network. Votes from the nodes of the consensus network are received. Whether a consensus is achieved in the votes is determined. Responsive to determining that the consensus is achieved, at least one of identification and verification of the image data may be provided.

The scattering surface, which may be an interface between distinct solid, liquid, gaseous or plasma phases, is illuminated with substantially spatially coherent light, and light scattered by the scattering surface is collected and dispersed, such as by a grating, into zeroth- and first-order beams. A spatial Fourier transform of the zeroth- and first-order beams is created, and one of the beams is low-pass filtered. The beams are interfered at a focal plane detector to generate an interferogram, which is transformed to retrieve a spatially resolved quantitative phase image and/or an amplitude image of the scattering surface. Imaging may be performed during an etching process, and may be used to adaptively control a photoetching process in a feedback loop.

  • Patent number: 9081521
    Abstract: A system and method provide a la carte reproduction services wherein a printing system is capable of performing multiple operational printing modes, but is configured, in a normal operational printing state, to perform a subset of the multiple operational printing modes. The printing system includes a user interface to enable a user to select an operational printing mode. The printing system, in response to a user selecting an operational printing mode not included in subset of the multiple operational printing modes, communicates with a printer service provider server to request authorization to perform the user selected operational printing mode. The printer service provider server requests predetermined information from the printing system, and, upon processing and verification of information received from the printing system, configures the printing system to perform the selected operational printing mode.

  • Patent number: 9053387
    Abstract: Each second selection circuit selects, out of a plurality of evaluation values, an evaluation value being in a predetermined relative positional relation with a first evaluation value as an evaluation value outputted from a first selection circuit, and outputs the selected value. The predetermined relative positional relations are different from one another among a plurality of second selection circuits. Every time a second evaluation value is outputted from the second selection circuit corresponding to the integration circuit, the integration circuit reads a weigh value corresponding to a combination of the second evaluation value and the first evaluation, which makes a pair with the second evaluation and is outputted from the first selection circuit, from a storage circuit corresponding to the second selection circuit and integrates the read values.

  • Patent number: 9041977
    Abstract: In an image processing apparatus, a ground color detecting unit is provided that detects ground color information indicating a ground color from input first image data. A storage unit stores a history of the ground color information detected by the ground color detecting unit, and a setting unit is also provided that sets a first threshold value that is a reference of the ground color based on a representative value of first ground color information indicating a first ground color included in the history stored in the storage unit. A ground color removing unit removes a ground color for input second image data based on the first threshold value which was set by the setting unit. A non-transitory computer readable medium storing a program is also provided, the program causing a processor to perform steps similar to those performed by the image forming apparatus.

  • Patent number: 9013770
    Abstract: In an image processing device, the control device identifies a background color of the image. The control device classifies each of the pixels into either one of a background color pixel group or a non-background color pixel group. The control device determines whether a partial region of the image having the non-background pixel is a chromatic color region or an achromatic color region, without using pixel values corresponding to pixels classified into the background color pixel group. The control device determines that the image is chromatic color image when it is determined that the partial region is the chromatic color region. The control device determines that the image is achromatic color image when it is determined that the partial region is the achromatic color region.

  • Patent number: 9007666
    Abstract: Erroneous determination of an image caused by color shift is prevented. Image data is divided in a sub-scanning direction into a first region where color shift hardly occurs and a second region where color shift easily occurs. There are detected a first color line drawing extending in a main-scanning direction in the first region, a second color line drawing extending in the main-scanning direction and having a width larger than that of the first color line drawing in the second region, and a third color line drawing extending in the sub-scanning direction in the image data. On the basis of the detected first, second, and third color line drawings, it is determined whether a document is a color document or not.
