Publication number: 20230298360Abstract: Certain aspects of the present disclosure provide techniques for lane marker detection. A set of feature tensors is generated by processing an input image using a convolutional neural network. A set of localizations is generated by processing the set of feature tensors using a localization network, a set of horizontal positions is generated by processing the set of feature tensors using row-wise regression, and a set of end positions is generated by processing the set of feature tensors using y-end regression. A set of lane marker positions is determined based on the set of localizations, the set of horizontal positions, and the set of end positions.Type: ApplicationFiled: March 18, 2022Publication date: September 21, 2023Inventors: Seungwoo YOO, Heesoo MYEONG, Hee-Seok LEE

Patent number: 11410040Abstract: Certain aspects of the present disclosure are directed to methods and apparatus for deep learning in an artificial neural network. One example method generally includes receiving input data at an input to a layer of the neural network; replicating a group of neural processing units in the layer to form a superset of neural processing units, the superset comprising n instances of the group of neural processing units; processing the input data using the superset to generate output data for the layer; and determining an uncertainty of the output data. Processing the input data includes performing a dropout function by zeroing out one or more weights of a set of weights for each of the n instances of the superset of neural processing units and convolving, for each of the n instances in parallel, the input data with one or more non-zeroed out weights of the set of weights.Type: GrantFiled: October 23, 2018Date of Patent: August 9, 2022Assignee: Qualcomm IncorporatedInventors: Seungwoo Yoo, Heesoo Myeong, Hee-Seok Lee, Hyun-Mook Cho

Patent number: 11195028Abstract: Disclosed are techniques for estimating multiple lane boundaries through simultaneous detection of lane markers (LM) and raised pavement markers (RPM). Conventional techniques for lane marker detection (LMD) comprises extracting and clustering line segments from a camera image, fitting the clustered lines to a geometric model, and selecting the multiple lanes using heuristic approaches. Unfortunately, in the conventional technique, an error from each step is sequentially propagated to the next step. Also there are no techniques to estimate both LMs and RPMs. A technique to simultaneously detect in real time both LM and RPMs is proposed. This enables optimal estimation of multiple lane boundaries.Type: GrantFiled: January 2, 2020Date of Patent: December 7, 2021Assignee: QUALCOMM IncorporatedInventors: Jeong-Kyun Lee, Young-Ki Baik, Seungwoo Yoo, Duck Hoon Kim
