  • Patent number: 11910121
    Abstract: Systems and methods are provided for generating color video from a dual-context camera. A dual-context camera provides a first series of video frames encoded in accordance with a full color model and a second series of video frames encoded in accordance with an underdetermined color model. The two series of video frames are interleaved as to form a series of pairs of frames, each comprising a color video frame and an underdetermined video frame. An image merger generates a composite image for each pair of frames in the series of frames. The composite image includes a set of brightness values from the underdetermined video frame and a set of chrominance values from the color video frame. A color video source replaces the underdetermined image in each of the series of pairs of frames with the composite image generated for the pair of frames to provide a color video stream.

  • Patent number: 11869227
    Abstract: Image recognition may include obtaining a first image, segmenting the first image into a plurality of first regions by using a target model, and searching for a target region among bounding boxes in the first image that use points in the first regions as centers. The target region is a bounding box in the first image in which a target object is located. The target model is a pre-trained neural network model configured to recognize from an image, a region in which the target object is located. The target model is obtained through training by using positive samples with a region in which the target object is located marked and negative samples with a region in which a noise is located marked. The target region is marked in the first image to improve accuracy of target object detection in an image.

  • Patent number: 11750760
    Abstract: An information loss determiner in an image processing device determines whether character collapse has occurred in a simple binarized image. If character collapse has not occurred in the simple binarized image, an image processing determiner selects simple binarization processing as the image processing method of output image data. If character collapse has occurred in the simple binarized image, the process proceeds to photograph area size determination. If the ratio of a photograph area size is less than or equal to a predetermined value, the information loss determiner determines that character collapse has occurred in a posterization processed image. If character collapse has occurred in the posterization processed image, the image processing determiner selects grayscale processing. If character collapse has not occurred in the posterization processed image, the image processing determiner selects posterization processing.

  • Patent number: 11354543
    Abstract: Methods and systems for training and utilizing an artificial neural network (ANN) are provided. In an example method, a computing device can receive an image pair, where a first image of the image pair includes a training image and a second image of the image pair includes a ground truth image. The computing device can provide instances of the first image to a plurality of image filtering modules and determine respective filtered representations of the first image using the plurality of image filtering modules. The computing device can indirectly train an adaptor ANN by applying the adaptor ANN on the respective filtered representations to produce an adapted representation; determining, using a trained colorization ANN, a colorized image from the adapted representation; and updating weights of the adaptor ANN based on a loss function that comprises a difference between the colorized image and the second image of the image pair.

  • Patent number: 11335048
    Abstract: A computing system and method for neural network-based image colorization is provided. The computing system obtains a reference color image by selective application of a color effect on a region of interest of an input image and controls a display device to display a first node graph on a Graphical User Interface of an image/video editing application. The first node graph includes a colorization node representing a first workflow for colorization of at least a first object in grayscale images of a first image feed. The computing system selects the reference color image based on a user input and executes the first workflow associated with the colorization node by feeding the reference color image and the first image feed as an input to a neural network-based colorization model. The computing system receives a second image feed comprising colorized images as output of the neural network-based colorization model for the input.

  • Patent number: 11182112
    Abstract: Example embodiments relate to creating ICC printer profiles with unorthodox ink limits. A printing device may initially print a color profile chart represented by color combinations that are equal to or below an ink limit and generate a first ICC profile based on the color profile chart. The first ICC profile uses a first color set to map input colors of a source color space to output colors of a destination color space. At least one color of the first color set, however, may be represented by a color combination that exceeds the ink limit and thus the printing device may determine a second color set based on the first color set. For the second color set, each color is represented by a color combination that is equal to or below the ink limit. A second ICC profile may be generated to use the second color set.

  • Patent number: 11151691
    Abstract: Systems and methods are provided for image scaling with enhanced compression. One embodiment is a processor that receives an instruction to scale an input image to create an output image that is higher in resolution, and analyzes rows of the input image in sections according to a run length of a predetermined number of consecutive pels. For each run length of consecutive pels, the processor determines a cluster of adjacent pels within the run length having a color intensity value within a threshold range, and determines a replacement intensity value for the cluster based on at least one color intensity value of a pel in the cluster. The processor creates the output image by: upscaling the cluster by the scale factor to multiply a number of pels in the cluster, and changing an intensity value of all pels in the cluster to the replacement intensity value.

    Abstract: To make it possible to specify a color space of image data even in a case where color space identification information is not attached to the image data. The image processing system that handles image data whose color spaces are different comprises a learning unit configured to perform machine learning by taking image data and metadata thereof as input data and color space identification information as supervised data. In the machine learning, a learning model is optimized so that a deviation between the color space predicted from the input data and the color space specified by the color space identification information becomes a minimum.

  • Patent number: 11119035
    Abstract: A computer system for identifying coating texture effects initiates a set of colorant decision points. The colorant decision points identify a probability that an effect pigment type is present within a target coating. The computer system calculates in parallel each colorant decision point within the set of colorant decision points. Each colorant decision point provides a probability that a different effect pigment type is present within the target coating. The computer system then calculates a set of final colorant probabilities. Each final colorant probability within the set of final colorant probabilities is calculated by combining a unique subset of probabilities calculated by the first set of colorant decision points. Additionally, each final colorant probability indicates a probability that an associated colorant is present within the target coating.

Color properties of the printed test patches are measured. In certain examples, a gamut descriptor is identified from a plurality of gamut descriptors using the color properties of the test colors. Each gamut descriptor defines a set of up-sampling parameters for a particular color gamut. Measured color properties for the initial color sample points are up-sampled using the set of up-sampling parameters for the identified gamut descriptor to generate up-sampled data. In certain cases, the up-sampled data is used to generate a color mapping to be applied to print job data received by the printing system.
