  • Patent number: 10089713
    Abstract: A method for registering images aligns a fixed image with a corresponding moving image. A target image and a reference image are selected. The reference and target images are relatively low-res representations of the fixed and moving images respectively. A current image distortion map is determined that defines distortions between the target and reference images. A residual image is determined by comparing the reference image and a warped target image derived from the target image based on the current image distortion map. A residual image distortion map is determined based on transform coefficients of cosine functions fitted to the residual image. The coefficients are determined by applying a DCT to a signal formed by the residual image and image gradients of the warped target or reference image. The current image distortion map is combined with the residual image distortion map to align the fixed image and the moving image.

  • Patent number: 10091469
    Abstract: An image processing apparatus can measure a three-dimensional shape of a subject with high accuracy when an image of a projection pattern is captured with a favorable contrast. The image processing apparatus includes a matching calculation unit that performs matching calculation between a projection pattern in an image being captured and an image of a projection pattern generated by a projection pattern generation unit. An image evaluation unit calculates a contrast as an evaluation standard in the captured image. A symbol position calculation unit highly accurately calculates a position of each of a group of points forming the projection pattern, for each area in the captured image determined to be a highly accurate shape measurable area based on the contrast, and thus obtains a peak luminance position. A three-dimensional shape calculation unit calculates the three-dimensional shape of the subject.
