Patent number: 11195331Abstract: A neural network may be used to determine corner points of a skewed polygon (e.g., as displacement values to anchor box corner points) that accurately delineate a region in an image that defines a parking space. Further, the neural network may output confidence values predicting likelihoods that corner points of an anchor box correspond to an entrance to the parking spot. The confidence values may be used to select a subset of the corner points of the anchor box and/or skewed polygon in order to define the entrance to the parking spot. A minimum aggregate distance between corner points of a skewed polygon predicted using the CNN(s) and ground truth corner points of a parking spot may be used simplify a determination as to whether an anchor box should be used as a positive sample for training.Type: GrantFiled: March 16, 2020Date of Patent: December 7, 2021Assignee: NVIDIA CorporationInventors: Dongwoo Lee, Junghyun Kwon, Sangmin Oh, Wenchao Zheng, Hae-Jong Seo, David Nister, Berta Rodriguez Hervas

Publication number: 20210166052Abstract: In various examples, one or more deep neural networks (DNNs) are executed to regress on control points of a curve, and the control points may be used to perform a curve fitting operation—e.g., Bezier curve fitting—to identify landmark locations and geometries in an environment. The outputs of the DNN(s) may thus indicate the two-dimensional (2D) image-space and/or three-dimensional (3D) world-space control point locations, and post-processing techniques—such as clustering and temporal smoothing—may be executed to determine landmark locations and poses with precision and in real-time. As a result, reconstructed curves corresponding to the landmarks—e.g., lane line, road boundary line, crosswalk, pole, text, etc.—may be used by a vehicle to perform one or more operations for navigating an environment.Type: ApplicationFiled: December 2, 2020Publication date: June 3, 2021Inventors: Minwoo Park, Yilin Yang, Xiaolin Lin, Abhishek Bajpayee, Hae-Jong Seo, Eric Jonathan Yuan, Xudong Chen

Publication number: 20200249684Abstract: In various examples, a path perception ensemble is used to produce a more accurate and reliable understanding of a driving surface and/or a path there through. For example, an analysis of a plurality of path perception inputs provides testability and reliability for accurate and redundant lane mapping and/or path planning in real-time or near real-time. By incorporating a plurality of separate path perception computations, a means of metricizing path perception correctness, quality, and reliability is provided by analyzing whether and how much the individual path perception signals agree or disagree. By implementing this approach—where individual path perception inputs fail in almost independent ways—a system failure is less statistically likely. In addition, with diversity and redundancy in path perception, comfortable lane keeping on high curvature roads, under severe road conditions, and/or at complex intersections, as well as autonomous negotiation of turns at intersections, may be enabled.Type: ApplicationFiled: February 4, 2020Publication date: August 6, 2020Inventors: Davide Marco Onofrio, Hae-Jong Seo, David Nister, Minwoo Park, Neda Cvijetic

Publication number: 20200090322Abstract: In various examples, a deep neural network (DNN) is trained for sensor blindness detection using a region and context-based approach. Using sensor data, the DNN may compute locations of blindness or compromised visibility regions as well as associated blindness classifications and/or blindness attributes associated therewith. In addition, the DNN may predict a usability of each instance of the sensor data for performing one or more operations—such as operations associated with semi-autonomous or autonomous driving. The combination of the outputs of the DNN may be used to filter out instances of the sensor data—or to filter out portions of instances of the sensor data determined to be compromised—that may lead to inaccurate or ineffective results for the one or more operations of the system.Type: ApplicationFiled: September 13, 2019Publication date: March 19, 2020Inventors: Hae-Jong Seo, Abhishek Bajpayee, David Nister, Minwoo Park, Neda Cvijetic

Publication number: 20200026960Abstract: In various examples, systems and methods are disclosed that preserve rich spatial information from an input resolution of a machine learning model to regress on lines in an input image. The machine learning model may be trained to predict, in deployment, distances for each pixel of the input image at an input resolution to a line pixel determined to correspond to a line in the input image. The machine learning model may further be trained to predict angles and label classes of the line. An embedding algorithm may be used to train the machine learning model to predict clusters of line pixels that each correspond to a respective line in the input image. In deployment, the predictions of the machine learning model may be used as an aid for understanding the surrounding environment—e.g., for updating a world model—in a variety of autonomous machine applications.Type: ApplicationFiled: July 17, 2019Publication date: January 23, 2020Inventors: Minwoo Park, Xiaolin Lin, Hae-Jong Seo, David Nister, Neda Cvijetic

Patent number: 10169637Abstract: Example methods, systems, computer-readable media, and apparatuses for on-screen optical fingerprint capture for user authentication are presented. These allow for the authentication of a fingerprint where the fingerprint image is propagated in a glass layer before being captured by a camera. In some examples, such propagation can result in multiple fingerprint images resulting from total internal reflection within the glass layer. Feature information can then be determined from the captured image of the fingerprint, which can include multiple fingerprint images. The amount of feature information can then be reduced. A histogram associated with the captured image based on the reduced number of features can be generated, and a user can be authenticated based on the histogram.Type: GrantFiled: October 18, 2016Date of Patent: January 1, 2019Assignee: Qualcomm IncorporatedInventors: Hae-Jong Seo, John Wyrwas

Patent number: 9454265Abstract: This disclosure provides systems, methods and apparatus for touch and gesture recognition, using a field sequential color display. The display includes a processor, a lighting system, and an arrangement for spatial light modulation that includes an array of light modulators. Each light modulator is switchable between an open position that permits transmittance of light from the lighting system through a respective aperture and a shut position that blocks light transmission through the respective aperture. The processor switches the light modulators in accordance with a first modulation scheme to render an image and in accordance with a second modulation scheme to selectively pass object illuminating light through at least one of the respective apertures. A light sensor receives light resulting from interaction of the object illuminating with an object and outputs a signal to the processor. The processor recognizes, from the output of the light sensor, a characteristic of the object.Type: GrantFiled: September 23, 2013Date of Patent: September 27, 2016Assignee: QUALCOMM IncorporatedInventors: John Michael Wyrwas, Paul Eric Jacobs, Evgeni Petrovich Gousev, Russell Wayne Gruhlke, Chung-Po Huang, Hae-Jong Seo, Xiquan Cui, Jacek Maitan
