  • Publication number: 20220207864
    Abstract: A method of classifying a media includes receiving a media file and extracting therefrom first and second data streams including first and second media content, respectively, the media content being associated with the media item. First and second feature vectors describing the first and second media content, respectively, are generated. At least a first single feature vector representing the first sequence of first feature vectors and the second sequence of second feature vectors is generated, or at least a first single feature vector representing at least the first sequence of first feature vectors is generated. A second feature vector representing at least the second sequence of second feature vectors is generated. A probability vector from the first single feature vector, or from the first and second single feature vectors is generated. A user profile suitability class is assigned to the media item based on the probability vector.

  • Patent number: 11232609
    Abstract: A method of displaying an image on a see-through display comprises: obtaining a first electro-magnetic radiation matrix of radiation intensity values of an object; dividing the first matrix into a second matrix representing a first subset of the radiation intensity values, and a third matrix representing a second subset of the radiation intensity values; generating a first grayscale image with an enhanced contrast representing the first subset of the radiation intensity values from the second matrix; colouring the first grayscale image with a first colourmap to obtain a first colour image; generating a second grayscale image representing the second subset of the radiation intensity values; colouring the second grayscale image with a second colourmap to obtain a second colour image; combining the first colour image and the second colour image; and displaying the combined colour image on the see-through display.

  • Patent number: 10593125
    Abstract: We disclose a method for synthesizing by computer an artwork where 2D and 3D contents are integrated within a same composition. Such an artwork creates plausible effects for the viewers by showing a different relationship between 2D and 3D at each viewing angle. Methods are proposed for ensuring the continuity between the 2D and the 3D parts in terms of mesh geometry and reflected colors. The user selects from a given scene a region of interest (ROI) to be reproduced in 3D. A flat rendering grid is created that matches the topology and tesselation of the ROI. The ROI is attached to the rendering grid. To enhance the continuity between the 2D and the 3D parts of a scene object, the 2D part of the object can be represented as bas-relief. Designers can create 2D-3D sculpture paintings for decoration, exhibitions, and homes.

  • Publication number: 20190297298
    Abstract: We present a method for hiding images in synthetic videos and reveal them by temporal averaging. We developed a visual masking method that hides the input image both spatially and temporally. Our masking approach consists of temporal and spatial pixel by pixel temporal variations of the frequency band coefficients representing the image to be hidden. These variations ensure that the target image remains invisible. In addition, by applying a temporal expansion function derived from a dither matrix, we allow the video to carry a visible message that is different from the hidden image. The image hidden in the video can be revealed by software averaging, or with a camera, by long exposure photography. The method finds applications in the secure transmission of digital information.

  • Patent number: 8633996
    Abstract: In previously known imaging devices as in still and motion cameras, for example, image sensor signal response typically is linear as a function of intensity of incident light. Desirably, however, akin to the response of the human eye, response is sought to be nonlinear and, more particularly, essentially logarithmic. Preferred nonlinearity is realized in image sensor devices of the invention upon severely limiting the number of pixel states, combined with clustering of pixels into what may be termed as super-pixels.

  • Patent number: 8634640
    Abstract: A method for selecting a color palette includes receiving a feature from an image of an object and a reference color chart, calculating a transform to correct a color in the imaged reference color chart, correcting a color in the feature using the transform, and selecting a color palette based on the corrected feature color. The reference color chart includes reference colors, and the transform corrects the color in the imaged reference color chart to substantially equal a corresponding reference color. An apparatus for selecting a color palette is also described.

  • Patent number: 8462238
    Abstract: The present invention aims to capture two images simultaneously in the visible part of the spectrum and a NIR image. This is achieved through a camera for simultaneously capturing a visible and near-infrared image by at least a sensor producing sensor response data and having at least one color filter array (CFA) comprising at least four different filters, said color filter array having visible and near-infrared light filters, and said camera comprising means to obtain a visible image while using the sensor response data from the visible part of the spectrum and a NIR image using the sensor response data from the near-infrared part of the spectrum.

  • Patent number: 7609230
    Abstract: A method and system is provided for creating a display and generating images. Creating the display includes receiving a transmissive display component over an emissive display component and positioning each emissive display pixel with one or more transmissive display pixels creating a display surface capable of displaying color images. Displaying images on the display surface includes decomposing image data associated with the image into separate chrominance signal levels and luminance signal levels, displaying the representation of the chrominance signal levels of the image by driving emissive display pixels in correspondence to the chrominance characteristic of the image, generating the representation of the luminance signal levels for display through the emissive display pixels of the emissive display component and filtering the displayed representation of the luminance signal level using transmissive display pixels in accordance with the luminance characteristics of the image.

  • Patent number: 7522769
    Abstract: Embodiments of the present invention recite a computer implemented method and system for estimating skin color from an image. In embodiments of the present invention, an image of a subject and of an imaged reference color set is accessed. In embodiments of the present invention, a controlled infrastructure is not required when capturing the image. At least one skin pixel of the subject is located in the image and a color description of the at least one skin pixel is determined. Then, a color correction function to be applied to the color description of the at least one skin pixel is determined. The color correction function is applied to the color description of the at least one skin pixel to create a modified color description. Finally, the skin color of the subject is estimated based upon an analysis of the modified color description.
