Abstract: A method and apparatus with pose estimation, where the method may include obtaining, using a depth network, a respective depth image for each of a plurality of successive input images, obtaining, using a pose network, respective image pose transformation matrices between images, of the successive input images, at adjacent time points, obtaining, based on initial pose information and the respective image pose transformation matrices, image pose information for each of the adjacent times, estimating final pose information dependent on the obtained image pose information, accumulating the image pose transformation matrices, calculating a pose loss value based on a result of comparing image position information, obtained from a result of the accumulating, and sensor position information obtained from a sensor. The pose and depth networks may be updated based on the pose loss value and a composite loss value dependent on the image pose transformation matrices and the input images.

Abstract: An air conditioner includes a housing including an inlet and an outlet, and a blade rotatably provided to open and close the outlet. A blade drive device is connected to one end of the blade in a longitudinal direction of the blade to rotate the blade. A blade support unit is configured to rotatably support the other end of the blade in the longitudinal direction of the blade. The blade support unit includes a coil spring configured to apply torque to the blade and a blade holder is coupled to the other end of the blade. A first coupler is coupled to the coil spring, and is configured to penetrate the coil of the coil spring. A case is configured to accommodate the first coupler of the blade holder and is mounted to the housing. The air conditioner is capable of reducing deformation and noise in a blade.

Abstract: Provided is a stereo matching method and apparatus. A stereo matching apparatus may generate a disparity map by transforming a disparity map of a previous frame based on determined motion information of a camera between the previous frame and the current frame, calculate a confidence for the generated disparity map, and adjust a disparity map corresponding to the current frame based on the confidence and the generated disparity map.

Abstract: A stereo matching method includes obtaining a first feature map associated with a first view image and a second feature map associated with a second view image using a neural network model-based feature extractor, determining respective matching costs between a reference pixel of the first view image and candidate pixels of the second view image using the first feature map and the second feature map, and determining a pixel corresponding to the reference pixel among the candidate pixels based on the determined matching costs.
