沉积-删除被广泛认为是地表深度有序化的决定性线索，沉积或删除表面被解释为在毗邻表面之后。然而，Froyen，Feldman和Singh已经证明，当等高线的两侧发生吸积-删除时，由于三维旋转，吸积-删除区域也可以被视为前方和自遮挡。在这项研究中，我们问几何图形-背景线索是否可以推翻传统的“深度来自增长-删除”的解释，即使当增长-删除只发生在等高线的一侧。我们使用了两个任务：相对深度任务(前/后)和运动分类任务(平移/旋转)。我们进行了两个实验，其中只有一组交替区域的纹理是移动的，而另一组是静态的。与传统的吸积-删除解释相反，在大约一半的试验中，移动的凸起和对称区域被认为是三维的和旋转的。在第二个实验中，给运动区域不同的运动方向(从而削弱了基于运动的分组)进一步削弱了传统的吸积-删除解释。我们的结果表明，标准的“深度从增长-删除”的解释被静态的几何线索覆盖到图形-背景。总体而言，研究结果表明，增加-删除、图形-背景和运动结构之间存在丰富的相互作用，而现有的运动深度模型并不能捕捉到这一点。
Accretion-deletion is widely considered a decisive cue to surface depth ordering, with the accreting or deleting surface interpreted as behind an adjoining surface. However, Froyen, Feldman, and Singh have shown that when accretion-deletion occurs on both sides of a contour, accreting-deleting regions can also be perceived as in front and as self-occluding due to rotation in three dimensions. In this study we ask whether geometric figure–ground cues can override the traditional “depth from accretion-deletion” interpretation even when accretion-deletion takes place only on one side of a contour. We used two tasks: a relative-depth task (front/back), and a motion-classification task (translation/rotation). We conducted two experiments, in which texture in only one set of alternating regions was moving; the other set was static. Contrary to the traditional interpretation of accretion-deletion, the moving convex and symmetric regions were perceived as figural and rotating in three dimensions in roughly half of the trials. In the second experiment, giving different motion directions to the moving regions (thereby weakening motion-based grouping) further weakened the traditional accretion-deletion interpretation. Our results show that the standard “depth from accretion-deletion” interpretation is overridden by static geometric cues to figure–ground. Overall, the results demonstrate a rich interaction between accretion-deletion, figure–ground, and structure from motion that is not captured by existing models of depth from motion.
