A camera calibration method and medium and a 3-dimensional (3D) object reconstruction method and medium using the camera calibration method are provided. The camera calibration method includes setting a feature track by tracking and matching features in an input image sequence; estimating 3-dimensional (3D) points in relation to the features by initializing a structure and motion of the camera; estimating a pose of the camera by using the 3D points and refining the structure of the camera based on the estimated pose; and refining the pose of the camera.

Provided are an apparatus, method, and medium for generating a panoramic image. In the apparatus, a previously captured image and a currently captured image are projected onto a predetermined curved surface so as to form a first mapping image and a second mapping image, respectively. Movement values in predetermined directions are calculated for maximizing a color similarity between overlapped sections of the first and second mapping images. A panoramic image is generated using the first and second mapping images and the calculated movement values. Therefore, overlapped sections of neighboring images can be precisely superposed and aligned when a panoramic image is generated using a series of images.

A modeling method, medium, and system. The modeling method may include specifying an object in a plurality of 2 dimensional (2D) images expressed from different view points, considering an edge and contents of each component of each 2D image, generating a 3 dimensional (3D) model of each specified object, and matching the generated 3D models considering relative locations of each generated 3D model. Accordingly, a realistic 3D model of an object expressed in an image can be accurately generated.

A modeling method, medium, and system. The modeling method identifies a object within an image by detecting edges within the image, determines a complexity of the identified object based upon detected surface orientations of the identified object relative to a defined surface of the image, selectively, based upon the determined complexity, generates one or more surfaces for a 3D model by identifying one or more vanishing points for one or more corresponding surfaces, respectively, of the identified object and respectively analyzing the identified one or more vanishing points relative to respective determined points of the one or more corresponding surfaces of the image, and generates the 3D model by combining the one or more surfaces in a 3D space.

Provided are an apparatus, method, and medium for processing an image. In the apparatus, at least one image selected from images to be stitched so as to make colors of overlapped sections of the images as identical with each other as possible and operating again in response to a re-alignment signal, and an image correction unit generating the re-alignment signal after correcting a color of at least a part of the overlapped sections as a result of the shifting of the at least one image in consideration of colors of the overlapped sections Then the shifting of the image is repeated. Therefore, even when the overlapped sections of the images are not identical in color, the overlapped sections of the images can be precisely aligned when the images are stitched for forming a panoramic image, thereby making the panoramic image more accurate.

A filtering system, medium, and method, including determining whether a size of a splat exceeds a predetermined size, smoothing a boundary of the splat if it is determined that the size of the splat exceeds the predetermined size, and sharpening the boundary of the splat if it is determined that the size of the splat does not exceed the predetermined size.
