Lenticular-based 2D anti-aliasing digital filtering method for stereo image
一种基于棱柱镜的立体图像二维抗混叠数字滤波方法

Based on the characteristic of lenticular-based LCD auto-stereo display and its corresponding stereo image, aiming to solve spectrum aliasing problem, this paper proposed a novel 2D anti-aliasing digital filtering method. This method analyzed multiview LCD sub-pixel arrangement of slant lenticular, established the corresponding sub-sampling model with multi-dimensional sampling theory, and designed the corresponding 2D digital filter, so that 2D spectrum anti-aliasing filtering was performed on each view image and the distortion of stereo image was effectively eliminated. Experimental results show that the proposed method is of low complexity, good filtering effect, and strong applicability to similar auto-stereo displays.
