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.
Claims25
A disparity estimation method performed by a processor, the disparity estimation method comprising:
- 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.
A disparity estimation apparatus comprising:
- an image acquirer configured to acquire a first image and a second image;
- and
- a processor configured to:
- extract a first image patch comprising a reference pixel from the first image,
- extract a second image patch comprising a target pixel corresponding to the reference pixel from the second image, and
- estimate 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.
A disparity estimation method performed by a processor, the disparity estimation method comprising:
- estimating an initial disparity having a first resolution between a reference pixel in a first image and a target pixel in a second image, the target pixel corresponding to the reference pixel;
- estimating a residual having a second resolution smaller than the first resolution from the first image and the second image using a residual model, the residual being an estimated difference between the initial disparity and an actual disparity between the reference pixel and the reference pixel;
- and
- correcting the initial disparity based on the residual to obtain a final disparity.
