    Abstract: 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.

    Abstract: An image generating method and apparatus are provided. The image generating method irradiates a light with a predetermined wavelength to a target object at a predetermined interval, passes a light having a wavelength required to generate a color image from among lights reflected from the target object, detects color values according to the passed light, generates a depth image of the target object using color values detected during a period in which the light with the predetermined wavelength is irradiated, and generates the color image of the target object using color values detected during a period other than the period in which the light with the predetermined wavelength is irradiated. Accordingly, the image generating method can generate a depth image having high resolution while maintaining the resolution of the color image.

    Abstract: 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.
