    • A method for determining if a first pixel and a second pixel belong to a same surface includes: determining a spatial-difference value for the first pixel and the second pixel; determining one or more vision-difference values for the first pixel and the second pixel; determining, from the spatial-difference value, an initial same-surface probability value for if the first pixel and the second pixel belong to the same surface; determining, from the one or more vision-difference values, a first vision-difference probability value for if the first pixel and the second pixel belong to the same surface; determining, from the spatial-difference value and the one or more vision-difference values, a second vision-difference probability value; determining, from the initial same-surface probability value, the first vision-difference probability value and the second vision-difference probability value, an improved same-surface probability value for if the first pixel and the second pixel belong to the same surface.
    • 一种用于确定第一像素和第二像素是否属于相同表面的方法包括:确定第一像素和第二像素的空间差值; 确定所述第一像素和所述第二像素的一个或多个视差值; 从所述空间差值确定如果所述第一像素和所述第二像素属于相同表面的初始相同面概率值; 从所述一个或多个视差值确定如果所述第一像素和所述第二像素属于相同表面的第一视差概率值; 从所述空间差值和所述一个或多个视差值确定第二视差概率值; 从所述初始相同概率值确定所述第一视差概率值和所述第二视差概率值,如果所述第一像素和所述第二像素属于相同表面,则确定改进的相同概率值。
