    摘要： A method and apparatus of correcting geometric information and providing a panoramic view. In the method of providing a panoramic view, a tilting vector (X′, Y′) is generated by applying matrices H(a,b) and HF to a source image vector (X,Y). The matrix H(a,b) is defined by distortion angles “b” towards a plane direction and a distortion angle “a” towards a depth direction of the source image, and the matrix HF is defined according to a camera parameter matrix K. Also, a two-dimensional vector (x,y) of a source image is converted into a three-dimensional vector (X,Y,W) on a retinal image plane having a unit radial distance from an origin of a ground plane. Also, a warped image width (WIW) is estimated from a width and a field of view (FOV) of the source image. A warping vector (x′,y′) is generated based on the converted vector (X,Y,W) and the WIW.

    摘要： An apparatus and method of providing a panoramic image, the method including: preparing images of a plurality of levels, which are made by scaling each of two source images at several rates; computing a Sum of Square Difference (SSD) between two corresponding images in each of the plurality of levels of the two source images to form an image stitched together; and when stitching the two images, the overlapping area is divided into a plurality of parts and each part is assigned a weight which is linearly applied respectively to the divided part of each source image for blending color. The apparatus includes stitching units to stitch source images together at the plurality of levels and blending units to color blend the source images in the overlapped area.

    摘要： An apparatus and method for bidirectionally inpainting an occlusion area appearing during generation of a virtual viewpoint image, using a foreground area and a background area based on a predicted volume are provided. The method includes receiving an input of a depth image and a color image, the depth image having depth information for a first viewpoint, and the color image having color information for the first viewpoint, generating a virtual viewpoint image at a second viewpoint based on the depth image and the color image, separating the virtual viewpoint image into a foreground area and a background area, based on the depth information and direction information regarding a direction from the first viewpoint to the second viewpoint, predicting a three-dimensional (3D) volume of the foreground area, and inpainting an occlusion area bidirectionally using the foreground area and the background area, based on the predicted 3D volume, the occlusion area being included in the virtual viewpoint image.
