    Abstract: An operation method of a navigation apparatus includes: obtaining valid global positioning system (GPS) data at a current time point corresponding to a current position of a target device; determining first neighboring map elements corresponding to a first region indicated by the valid GPS data at the current time point from among a plurality of map elements of map data; and determining a pose parameter of the target device at the current time point based on a first direction specified by at least a portion of the first neighboring map elements.

    Abstract: A processor-implemented method includes: estimating, from frame images of consecutive frames acquired from one or more sensors, short-term ego-motion information of the one or more sensors; estimating long-term ego-motion information of the one or more sensors from the frame images; determining attention information from the short-term ego-motion information and the long-term ego-motion information; and determining final long-term ego-motion information of a current frame, of the consecutive frames, based on the long-term ego-motion information and the attention information.

    Abstract: A disparity estimation method performed by a processor includes extracting a first image patch comprising a reference pixel from a first image, extracting a second image patch comprising a target pixel corresponding to the reference pixel from a second image, and estimating a residual of an initial disparity between the reference pixel and the target pixel from the first image patch and the second image patch using a residual model, the residual being an estimated difference between the initial disparity and an actual disparity between the reference pixel and the target pixel.
