  • Image processing method and medium to extract a building region from an image
    Patent number: 8744177
    Abstract: Provided is a method of performing an image segmentation so as to extract a building region from an input color image. The method includes extracting a plurality of straight lines that pass through a vanishing point and determining the building region in the image based on color values around the plurality of straight lines.
    Type: Grant

  • Method for determining ground line
    Patent number: 8395824
    Abstract: A method of determining a ground line from an input image. The method includes determining a plurality of ground line candidates from the image, determining a certain band a central-line of which is a boundary between a G region and other regions in a Ground Building Sky (GBS) map of the image, and determining the ground line of the image by selecting a ground line candidate, among the plurality of ground line candidates, having the greatest extent crossing the certain band.

  • Image generating method and apparatus
    Patent number: 7718946
    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.
