    • PURPOSE: A method and an apparatus for regenerating a three-dimensional image from a two-dimensional image are provided to improve a noise removal effect compared with a linear filtering method by processing images through a non-linear filtering method according to a median value. CONSTITUTION: A recovery image generator(310) creates a three-dimensional recovery image through reverse projection using a pixel value corresponding to a median value among pixel values of images. The images are created by the two-dimensional projection of a target to be three-dimensionally recovered. A re-projection image generator(320) creates a two-dimensional re-projected image through the re-projection of the three-dimensional recovered image. A residual image forming part(330) constitutes a residual image according to the difference between the projected image and the two-dimensional re-projected image.
    • 目的:提供一种用于从二维图像再生三维图像的方法和装置,以通过根据中值的非线性滤波方法处理图像而与线性滤波方法相比提高噪声去除效果。 构成:恢复图像生成器(310)通过使用与图像的像素值之间的中值对应的像素值的反投影来创建三维恢复图像。 图像通过三维恢复的目标的二维投影来创建。 再投影图像生成器(320)通过三维恢复图像的重新投影产生二维再投影图像。 残留图像形成部(330)根据投影图像与二维再投影图像之间的差构成残差图像。
