摘要： Provided are an apparatus and method for generating panorama images and an apparatus and method for tracking an object using the same. The apparatus for generating panorama images estimates regional motion vectors with respect to respective lower regions set in an image frame, determines a frame motion vector by using the regional motion vectors based on a codebook storing sets of normalized regional motion vectors corresponding to a camera's motion and then accumulates motion mediating variables computed with respect to respective continuous image frames to determine an overlapping region, and matches the overlapping regions to generate a panorama image. The apparatus for tracking an object sets the panorama image generated by the apparatus for generating panorama images as a background image, and determines an object region by averaging pixel value difference values between pixels that constitute a captured input image and corresponding pixels in the panorama image. Regional motion vectors are estimated by using the coordinate of a pixel selected in lower regions, and thus a computing process can be simplified and a process speed can be increased. In addition, effects of wrongly estimated regional motion vectors can be minimized by using a codebook. Furthermore, noises are minimized and an object can be accurately extracted by using averaged pixel value difference values.

摘要： Provided are an apparatus and method for aligning color channels on the basis of depth information on an image taken by an imaging device equipped with a multiple color-filter aperture (MCA). An image divider generates a binary image including edge information on an original image, and generates a label map including a plurality of regions of interest (ROIs) respectively corresponding to a plurality of objects included in the original image. A shifting vector estimator estimates color shifting vectors (CSVs) indicating shift directions and distances of color channels of the original image according to the respective ROIs. A channel matching unit obtains a plurality of matched images corresponding to the respective ROIs included in the label map by shifting the color channels according to the respective CSVs, and generates a multi-focus image by combining the matched images.
