    Abstract: An apparatus and a method for reducing aliasing effects of multi-view images are provided to adaptively adjust strength of low frequency filtering according to stereoscopic parallax or variation of a pixel. A multi-view image input unit(100) transmits N multi-view images to a pixel parallax calculating unit(200). The pixel parallax calculating unit calculates a parallax value of a pixel from the multi-view image/multi-view depth data. A filtering strength calculating unit(300) calculates filtering strength corresponding to the parallax value calculated in the pixel parallax calculating unit. A filter unit filters a pixel configuring the multi-view image corresponding to the filtering strength calculated in the filtering strength calculating unit.

    Abstract translation: 提供一种用于减少多视图图像的混叠效应的装置和方法,以根据立体视差或像素的变化自适应地调整低频滤波的强度。 多视点图像输入单元(100)将N个多视图图像发送到像素视差计算单元(200)。 像素视差计算单元从多视点图像/多视角深度数据计算像素的视差值。 滤波强度计算单元(300)计算与在像素视差计算单元中计算的视差值对应的滤波强度。 滤波器单元对构成与在滤波强度计算单元中计算的滤波强度相对应的多视点图像的像素进行滤波。
