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.
