    • Provided is a depth image unfolding apparatus and method that may remove a depth fold from a depth image to restore a three-dimensional (3D) image. The depth image unfolding apparatus may include an input unit to receive inputted multiple depth images with respect to the same scene, the multiple depth images being photographed based on different modulation frequencies of a fixed photographing device, a depth fold estimator to estimate a number of depth folds based on a distance between multiple three-dimensional (3D) points of multiple pixels indicating the same location of the scene in the multiple depth images, and an output unit to output the multiple depth images from which depth folds are removed based on the estimated number of depth folds.
    • 提供了可以从深度图像去除深度折叠以恢复三维(3D)图像的深度图像展开装置和方法。 深度图像展开装置可以包括:输入单元,用于接收关于相同场景的输入的多个深度图像,基于固定拍摄装置的不同调制频率拍摄多个深度图像;深度折叠估计器,用于估计多个深度 基于指示多个深度图像中的场景的相同位置的多个像素的多个三维(3D)点之间的距离的折叠,以及输出单元,用于输出从其中去除深度折叠的多个深度图像 深度折叠数。

    • Provided are an apparatus and method for converting a low-resolution depth image to a depth image having a resolution identical to a resolution of a high-resolution color image. The depth image conversion apparatus may generate a discrete depth image by quantizing a depth value of an up-sampled depth image, estimate a high-resolution discrete depth image by optimizing an objective functions of the discrete depth image based on the high-resolution color image and an up-sampled depth border, and convert the up-sampled depth image to a high-resolution depth image by filtering the up-sampled depth image when a difference between discrete depth values of neighboring pixels in the high-resolution discrete depth image is less than a predetermined threshold value.
    • 提供了一种用于将低分辨率深度图像转换为具有与高分辨率彩色图像的分辨率相同的分辨率的深度图像的装置和方法。 深度图像转换装置可以通过量化上采样深度图像的深度值来生成离散深度图像,通过基于高分辨率彩色图像优化离散深度图像的目标函数来估计高分辨率离散深度图像 以及上取样的深度边界,并且当高分辨率离散深度图像中的相邻像素的离散深度值之间的差异是高分辨率深度图像时,通过对上采样深度图像进行滤波,将上采样深度图像转换为高分辨率深度图像 小于预定阈值。
