An apparatus and method for bidirectionally inpainting an occlusion area appearing during generation of a virtual viewpoint image, using a foreground area and a background area based on a predicted volume are provided. The method includes receiving an input of a depth image and a color image, the depth image having depth information for a first viewpoint, and the color image having color information for the first viewpoint, generating a virtual viewpoint image at a second viewpoint based on the depth image and the color image, separating the virtual viewpoint image into a foreground area and a background area, based on the depth information and direction information regarding a direction from the first viewpoint to the second viewpoint, predicting a three-dimensional (3D) volume of the foreground area, and inpainting an occlusion area bidirectionally using the foreground area and the background area, based on the predicted 3D volume, the occlusion area being included in the virtual viewpoint image.

Provided is point-based efficient three-dimensional (3D) information representation from a color image that is obtained from a general Charge-Coupled Device (CCD)/Complementary Metal Oxide Semiconductor (CMOS) camera, and a depth image that is obtained from a depth camera. A 3D image processing method includes storing a depth image associated with an object as first data of a 3D data format, and storing a color image associated with the object as color image data of a 2D image format, independent of the first data.

Provided are an apparatus and a method for high speed filtering of an image for high precision that may include a coordinate determining unit to determine coordinates (P,Q) on a screen with respect to a first pixel to be filtered, a pixel determining unit to determine a second pixel with coordinates including either P or Q, a block setting unit to set a first block comprising the first pixel, and a second block comprising the second pixel, and a processing unit to filter the first pixel by comparing the first block and the second block.
摘要:
Provided are a method and an apparatus for image processing. A scene includes a low resolution depth image and a high resolution color image. A depth image up-scaler up-scales the depth image using an interpolation so as to improve the resolution of the depth image. A color-depth similarity based filter removes noise from the up-scaled depth image using the color image and the up-scaled depth image. A boundary sharpening filter converts a boundary between objects in the up-scaled depth image into a clearer boundary. The resolution of the depth image may increase to the level of the resolution of the color image by means of the depth image up-scaler, the color-depth similarity based filter and the boundary sharpening filter, and the depth of each pixel in the depth image may be adjusted.

An image generating apparatus may include a first reflector and a second reflector. When a light emitter emits an infrared light, the infrared light may be reflected from a first reflector and be omni-directionally reflected. The reflected infrared light that is the infrared light reflected from the object may be reflected from a second reflector and be transferred to a sensor. The sensor may receive the reflected infrared light and generate a depth image of the object.

A method and apparatus for temporally interpolating a three-dimensional (3D) depth image are provided to generate an intermediate depth image in a desired time. The apparatus may interpolate depth images generated by a depth camera, using a temporal interpolation procedure, may generate an intermediate depth image in a new time using the interpolated depth images, and may combine the generated intermediate depth image with color images, to generate a high-precision 3D image.
