Abstract: Systems and methods related to video encoding and decoding using decoder-side intra mode derivation (DIMD) are described. In an exemplary method of coding samples in a block in a video, an intra coding mode is selected based on a plurality of reconstructed samples in a template region adjacent to the block, and the samples in the block are predicted with intra prediction using the selected intra coding mode. The intra coding mode may be selected by testing a plurality of candidate intra coding modes for cost (e.g. distortion) of predicting the template region from a set of reconstructed reference samples. The mode with the lowest cost is used for prediction. In exemplary embodiments, explicit signaling of the intra mode is not required.

Abstract: A vehicular trailer assist system includes a camera disposed at a rear portion of a vehicle and viewing a portion of a trailer hitched at a hitch of the vehicle. During a reversing maneuver of the vehicle and hitched trailer, the vehicular trailer assist system, responsive to processing at an electronic control unit (ECU) of image data captured by the camera, determines a trailer angle of the trailer relative to a longitudinal axis of the vehicle. Based at least in part on the determined trailer angle, the vehicular trailer assist system determines a trailer direction of movement of the trailer while the vehicle is reversing with the trailer hitched at the hitch of the vehicle. The vehicular trailer assist system determines a virtual destination location rearward of the trailer and in the determined trailer direction and controls steering of the vehicle to reverse the trailer towards the virtual destination location.

Abstract: An image decoding method according to the present invention includes reconstructing a residual block by inverse-quantizing and inverse-transforming an entropy-decoded residual block, generating a prediction block by performing intra prediction on a current block, and reconstructing an picture by adding the reconstructed residual block to the prediction block, wherein generating the prediction block includes generating a final prediction value of a prediction target pixel included in the current block based on a first prediction value of the prediction target pixel and a final correction value calculated by performing an arithmetic right shift on a two's complementary integer representation for an initial correction value of the prediction target pixel by a binary digit of 1. Accordingly, upon image encoding/decoding, computation complexity may be reduced.

Abstract: An under-display camera is positioned underneath a display of a mobile device. The under-display camera captures an image using light passing through a portion of the display. The mobile device displays a display image on the display, the display image based on the image. The mobile device displays an indicator overlaid over the display image on an indicator area of the display that overlaps with the portion of the display. The indicator may identify the position of the camera. The mobile device can compensate for occlusion of the camera by continuing to display a previous display image if a more recently captured image includes an occlusion. The mobile device can give users alternate ways to select areas of the display image to avoid camera occlusion, for instance using hardware buttons and/or touchscreen interface elements.

Abstract: The present disclosure relates to visualizing an operative field in the context of a dental operating theater, and more specifically, to a portable, modular, multifunctional intraoral imaging system to assist a practitioner in performing a medical or dental procedure in a confined space (e.g., intraoral cavity or mouth of a patient). The system may include an intraoral camera apparatus having a camera unit equipped with a wireless transmitter, and a viewscreen mounted to an articulated stand or dental delivery unit, wherein the camera wirelessly may transmit an image to a viewscreen located directly in front of a dental practitioner. The practitioner may look directly ahead at a high-definition screen to view the operative field. A dental practitioner may use the apparatus to perform micro-surgical procedures in a confined operative area with less-than-ideal visibility and access, without the present, though generally accepted, physical difficulties and limitations.

Abstract: Described is a system for detecting and correcting perception errors in a perception system. In operation, the system generates a list of detected objects from perception data of a scene, which allows for the generation of a list of background classes from backgrounds in the perception data associated with the list of detected objects. For each detected object in the list of detected objects, a closest background class is identified from the list of background classes. Vectors can then be used to determine a semantic feature, which is used to identify axioms. An optimal perception parameter is then generated, which is used to adjust perception parameters in the perception system to minimize perception errors.
