Six experiments investigated the preattentive segregation of line-like patterns composed of discrete elements in a background of distractors. The results indicate that other factors in addition to spatial density influence line segregation. Edge alignment, edge length and principal axis orientation also affect line segregation. Differences in the outputs of Gabor filters fail to account for the perceived segregation of the lines. Possible models of line segregation based on element grouping, feature density and search are briefly discussed.
六项实验研究了在干扰物背景中由离散元素组成的线状图案的前注意分离。结果表明，除空间密度外，其他因素也会影响线条分离。边缘对齐、边缘长度和主轴方向也会影响线条分离。伽柏滤波器输出的差异无法解释线条的感知分离。本文简要讨论了基于元素分组、特征密度和搜索的线条分离的可能模型。
