    摘要: A depth noise filtering method and apparatus is provided. The depth noise filtering method may perform spatial filtering or temporal filtering according to depth information. In order to perform spatial filtering, the depth noise filtering method may determine a characteristic of a spatial filter based on depth information. Also, in order to perform temporal filtering, the depth noise filtering method may determine a number of reference frames based on depth information. The depth noise filtering method may adaptively remove depth noise according to depth information and thereby enhance a noise filtering performance.

    摘要: An image processing method which determines and depth-unfolds a depth folding region in an input depth image. A depth folding region of an input depth image may be determined based on a variance of the input depth, image or a gradient image. A predetermined first depth value may be added to a depth value of each pixel of the determined depth folding region and depth information of the input depth image may be updated.

    摘要: Provided is an image processing apparatus, medium, and method. The image processing apparatus may include a first calculator and a second calculator. The first calculator may calculate a first weight of a first frame depth value of a first pixel of a depth image and a second weight of a second frame depth value of the first pixel, based on an obtainment time difference between the first frame depth value of the first pixel and the second frame depth value of the first pixel among a plurality of frame depth values of the first pixel. The second calculator may determine a corrected first frame depth value of the first pixel using a linear sum that is calculated by applying the first weight to the first frame depth value of the first pixel, and by applying the second weight to the second frame depth value of the first pixel.

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.
