Publication number: 20210192231Abstract: Autonomous driving systems described herein provide an efficient way to manage camera-based perception by considering the characteristics of captured images. In one example, a camera sensor may capture an image and a processor may determine a first region of interest (ROI) within the image and a second ROI within the image. The processor may generate a first image of the first ROI and a second image of the second ROI. The processor may transmit a control signal based on one or more objects detected in the first ROI and/or one or more objects detected in the second ROI to cause the vehicle to perform an autonomous driving operation.Type: ApplicationFiled: December 20, 2019Publication date: June 24, 2021Inventors: Hee-Seok LEE, Heesoo MYEONG, Hankyu CHO

Publication number: 20200219316Abstract: Disclosed are techniques for estimating a 3D bounding box (3DBB) from a 2D bounding box (2DBB). Conventional techniques to estimate 3DBB from 2DBB rely upon classifying target vehicles within the 2DBB. When the target vehicle is misclassified, the projected bounding box from the estimated 3DBB is inaccurate. To address such issues, it is proposed to estimate the 3DBB without relying upon classifying the target vehicle.Type: ApplicationFiled: January 2, 2020Publication date: July 9, 2020Inventors: Young-Ki BAIK, Hyun-Mook CHO, Duck Hoon KIM, Jeong-Kyun LEE, ChaeSeong LIM, Hee-Seok LEE

Publication number: 20200125953Abstract: 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: ApplicationFiled: October 23, 2018Publication date: April 23, 2020Inventors: Seungwoo YOO, Heesoo MYEONG, Hee-Seok LEE, Hyun-Mook CHO
