Abstract: An image synthesizing method according to the present invention includes generating a depth image in a current picture by searching depth information using a plurality of color images obtained at different view points, performing filtering on the depth image using a 3-dimensional (3D) joint bilateral filter, and generating a synthesized image using the plurality of color images and the filtered depth image, wherein the 3D joint bilateral filter performs filtering on the generated depth image using color image information for at least one of previous pictures, the current picture, and subsequent pictures, and the color image information includes information on a boundary of an object in the color images and color information of the color images. According to the present invention, image processing performance may be enhanced.

Abstract: Disclosed herein a method of removing a point cloud outlier and an apparatus implementing the method. The method includes: arranging a point cloud obtained from a laser scanner along at least a first direction; selecting, neighboring first-axis points, between which a separation degree satisfies an inspection start threshold condition, as a first leading-side representative point and a first trailing-side representative point; selecting a first leading-side outlier candidate and a first trailing-side outlier candidate based on a first leading-side separation degree and a first trailing-side separation degree; and determining the first leading-side outlier candidate and the first trailing-side outlier candidate as a first outlier point, when the number of the outlier candidates satisfies an allowable threshold condition.

Abstract: Provided is a parallax minimization stitching method and apparatus using control points in an overlapping region. A parallax minimization stitching method may include defining a plurality of control points in an overlapping region of a first image and a second image received from a plurality of cameras, performing a first geometric correction by applying a homography to the control points, defining a plurality of patches based on the control points, and performing a second geometric correction by mapping the patches.
