Patent number: 11983828Abstract: Insertion of supplemental content into a virtual environment is automated using a machine learning model. The machine learning model is trained to calculate a confidence value that a candidate virtual object fits into a virtual environment based on an input that includes a candidate virtual object, a list of persistent virtual objects, and a list of temporary virtual objects. The machine learning model is trained using the persistent and temporary objects displayed in the current virtual environment until it predicts that a selected virtual object fits into the current virtual environment. The trained machine learning model is then used to select a virtual object comprising supplemental content to be inserted as a new virtual object in the virtual environment.Type: GrantFiled: January 11, 2022Date of Patent: May 14, 2024Assignee: ROVI GUIDES, INC.Inventors: Aashish Goyal, Ajay Kumar Mishra, Jeffry Copps Robert Jose

Patent number: 11893111Abstract: Techniques are disclosed for detecting adversarial attacks. A machine learning (ML) system processes the input into and output of a ML model using an adversarial detection module that does not include a direct external interface. The adversarial detection module includes a detection model that generates a score indicative of whether the input is adversarial using, e.g., a neural fingerprinting technique or a comparison of features extracted by a surrogate ML model to an expected feature distribution for the output of the ML model. In turn, the adversarial score is compared to a predefined threshold for raising an adversarial flag. Appropriate remedial measures, such as notifying a user, may be taken when the adversarial score satisfies the threshold and raises the adversarial flag.Type: GrantFiled: November 26, 2019Date of Patent: February 6, 2024Assignee: Harman International Industries, IncorporatedInventors: Srinivas Kruthiveti Subrahmanyeswara Sai, Aashish Kumar, Alexander Kreines, George Jose, Sambuddha Saha, Nir Morgulis, Shachar Mendelowitz

Patent number: 10110869Abstract: A color preview image is generated, preferably in real-time, for a plenoptic imaging system. The raw plenoptic image has a structure containing superpixels and also contains different color channels. For a principal color channel, a center view is generated by determining the pixel value for a center view of the superpixel, i.e. at the centroid of the superpixel. For each of the other color channels, the ratio of that color channel to the principal color channel is calculated for each superpixel. A center view for each non-principal color channel is determined by multiplying the color ratios times the pixel values for the principal color center view. These center views for the principal and non-principal color channels are combined into a color preview image. The calculations preferably can be performed in real-time at video rates.Type: GrantFiled: March 8, 2017Date of Patent: October 23, 2018Assignee: Ricoh Company, LTD.Inventor: Aashish Kumar
