20110038529 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - Image retargeting is appropriately performed on stereo pair images composed of at least two images such as in three-dimensional displays. A path of connected pixels in first image data is calculated based on pixel gradient energy. Each pixel in second image data corresponding to each pixel in connected pixels in the first image data is calculated as an initial search point, based on the stereo correspondence relationship between the first image data and the second image data. Pixels that minimize energy between pixels of the first image data and pixels of the second image data in the proximity of the initial search point is calculated as a path of connected pixels in the second image data. A path of optimal connected pixels in the first image data is calculated using the energy. | 2011-02-17 |
20110038530 | ENHANCED OBJECT RECONSTRUCTION - Processing images includes projecting an infra-red pattern onto a three-dimensional object and producing a first image, a second image, and a third image of the three-dimensional object while the pattern is projected on the three-dimensional object. The first image and the second image include the three-dimensional object and the pattern. The first image and the second image are produced by capturing at a first camera and a second camera, respectively, light filtered through an infra-red filter. The third image includes the three-dimensional object but not the pattern. Processing the images also includes establishing a first-pair correspondence between a portion of pixels in the first image and a portion of pixels in the second image. Processing the images further includes constructing, based on the first-pair correspondence and the third image, a two-dimensional image that depicts a three-dimensional construction of the three-dimensional object. | 2011-02-17 |
