    Abstract: ADAS includes a processing circuit and a memory which stores instructions executable by the processing circuit. The processing circuit executes the instructions to cause the ADAS to receive, from a vehicle that is in motion, a video sequence, generate a position image including at least one object included in the stereo image, generate a second position information associated with the at least one object based on reflected signals received from the vehicle, determine regions each including at least a portion of the at least one object as candidate bounding boxes based on the stereo image and the position image, and selectively adjusting class scores of respective ones of the candidate bounding boxes associated with the at least one object based on whether a respective first position information of the respective ones of the candidate bounding boxes matches the second position information.

    Abstract: An apparatus for an artificial neural network includes a format converter, a sampling unit, and a learning unit. The format converter generates a first format image and a second format image based on an input image. The sampling unit samples the first format image using a first sampling scheme to generate a first feature map, and samples the second format image using a second sampling scheme different from the first sampling scheme to generate a second feature map. The learning unit operates the artificial neural network using the first feature map and the second feature map.

    Abstract: An electronic device includes: a first image sensor that outputs a first image produced by photographing a first viewing angle; a second image sensor that outputs a second image produced by photographing a second viewing angle that overlaps a portion of the first viewing angle; a third image sensor that outputs a third image produced by photographing a third viewing angle; and a processor that performs object detection on an object included in an image. The processor generates disparity information indicating a separation degree of a feature point of the first and second images, transforms the third image based on the disparity information, and performs object detection on the transformed third image.
