  • Publication number: 20240127470
    Abstract: In a method of predicting a position of an object at a future time point for a vehicle, video image information at a current time point and at a plurality of time points before the current time point acquired through a camera of the vehicle may be extracted as semantic segmentation image. A mask image imaging an attribute and position information of an object present in each of the video images may be extracted. A position distribution of the object may be predicted by deriving a plurality of hypotheses for a position of the object at a future time point through deep learning by receiving video images at the current time point and the time points before the current time point, a plurality of semantic segmentation images, a plurality of mask images, and ego-motion information of the vehicle, and calculating the plurality of hypotheses as a Gaussian mixture probability distribution.

  • Patent number: 11094762
    Abstract: Disclosed is a display device. In accordance with the display device, before an organic stack of a light-emitting diode is formed, a sticker is attached to a substrate, while a camera hole-forming portion and a margin area around the same are present, to form the organic stack, and the sticker and components on top of the sticker, such as the organic stack, are removed, so that the edge of the organic stack can be aligned without any additional process using separate masks and the reliability of the display device can be improved due to the provision of the organic stack at a location spaced apart from the camera hole by the margin area.
