  • Patent number: 11461937
    Abstract: Embodiments of the present disclosure relate to computer storage, methods, and systems for the automatic optimization of accessible color themes. Systems and methods are disclosed that leverage the use of confusion lines to identify and highlight relationships between colors that may be inaccessible (e.g., indistinguishable) for a person with a vision impairment, such as a color vision deficiency. In some embodiments, a set of input colors can be automatically optimized for color accessibility using confusion lines. The set of input colors can be optimized utilizing an objective function, including at least one of a CVD alignment term, out-of-gamut term, distinguishability term, and faithfulness term.

  • Patent number: 11461931
    Abstract: Provided are systems and methods to perform colour extraction from swatch images and to define new images using extracted colours. Source images may be classified using a deep learning net (e.g. a CNN) to indicate colour representation strength and drive colour extraction. A clustering classifier is trained to use feature vectors extracted by the net. Separately, pixel clustering is useful when extracting the colour. Cluster count can vary according to classification. In another manner, heuristics (with or without classification) are useful when extracting. Resultant clusters are evaluated against a set of (ordered) expected colours to determine a match. Instances of standardized swatch images may be defined from a template swatch image and respective extracted colours using image processing. The extracted colour may be presented in an augmented reality GUI such as a virtual try-on application and applied to a user image such as a selfie using image processing.

  • Patent number: 11380001
    Abstract: A controller for qualifying image registration includes a memory that stores instructions; and a processor that executes the instructions. When executed by the processor, the instructions cause the controller to execute a process that includes receiving first imagery of a first modality and receiving second imagery of a second modality. The process executed by the controller also includes registering the first imagery of the first modality to the second imagery of the second modality to obtain an image registration. The image registration is subjected to an automated analysis as a qualifying process to qualify the image registration. The image registration is variably qualified when the image registration passes the qualifying process, and is not qualified when the image registration does not pass the qualifying process.

  • Patent number: 11381707
    Abstract: There are disclosed techniques for error diffusion for printing. For example, there is disclosed a device comprising a pixel selector, to select a pixel from an image to be printed, wherein the pixel is associated to a group of device state probabilities, wherein each device state probability describes a probability of choosing a particular device state, wherein each device state describes the quantity of each colorant to be used in correspondence of the pixel. The device may comprise a device state determiner, to choose the device state for the selected pixel on the basis of the device state probabilities associated to the selected pixel. The device may comprise a feedback chain, to diffuse device state probability errors to pixels to be subsequently selected. The feedback chain may include a selected pixel error determiner, to determine device state probability errors for each device state probability of the selected pixel.

  • Patent number: 11366620
    Abstract: A color management system for a printing system includes a fleet color management service that manages color calibration for printing devices. Calibration target print jobs are sent to the printing devices within a group. The calibration target print jobs are measured to capture color printing data. The measured data is uploaded to the fleet color management service, which determines color printing parameters for the group, including an aggregate maximum end point target. The fleet color management service generates a tone reproduction curve for all of the printing devices based on the color printing parameters. Validation of the color printing capabilities are performed using a validation set of the printing devices to determine the validation set printing devices can meet the aggregate maximum end point target.
