感知物体的空间布局是视觉场景感知的关键。光学流程提供有关空间布局的信息。这不受图像模糊的影响,因为运动检测技术在图像结构中使用低空间频率。因此,在视觉流可用的情况下,感知具有模糊锡永的场景应该是有效的。此外,当模糊图像与视流相互作用时,视流可确定空间关系,校正模糊图像。校准的图像结构,然后在运动停止后保留由光流指定的空间关系。因此,当光流和模糊图像可用时,感知模糊场景应该是稳定的。我们研究了影响模糊场景识别的视流类型,并对视觉稳定性进行了评价。当观看包含平移流(实施例1)、旋转流(实施例2)或两者(实施例3)的单个帧和整个视频时,在模糊视频中识别场景。当第一次看到模糊的图像时,我发现了一些场景。当观看模糊视频片段时,无论是单独使用还是与旋转流结合使用,他们的表现都得到了改善。一周后,帕提克仍然能够从静态模糊图像中感知场景。因此,平移流输入端与模糊的图像结构一起作用,以产生有效且稳定的场景效果。这些结果表明,具有模糊锡永的观察者在他们不注意时可能能够识别他们的周围环境。
Per​ceiv​ing the spa​tial lay​out of ob​jects is cru​cial in vi​sual scene per​cep​tion. Op​tic flow pro​vides in​for​ma​‐ tion about spa​tial lay​out. This in​for​ma​tion is not af​fected by im​age blur be​cause mo​tion de​tec​tion uses low spa​tial fre​quen​cies in im​age struc​ture. There​fore, per​ceiv​ing scenes with blurry vi​sion should be ef​fec​tive when op​tic flow is avail​able. Fur​ther​more, when blurry im​ages and op​tic flow in​ter​act, op​tic flow spec​i​fies spa​tial re​la​tions and cal​i​brates blurry im​ages. Cal​i​brated im​age struc​ture then pre​serves spa​tial re​la​tions spec​i​fied by op​tic flow af​ter mo​tion stops. Thus, per​ceiv​ing blurry scenes should be sta​ble when op​tic flow and blurry im​ages are avail​able. We in​ves​ti​gated the types of op​tic flow that fa​cil​i​tate recog​ni​tion of blurry scenes and eval​u​ated the sta​bil​ity of per​for​mance. Par​tic​i​pants iden​ti​fied scenes in blurry videos when view​ing sin​gle frames and the en​tire videos that con​tained trans​la​tional flow (Ex​per​i​ment 1), ro​ta​tional flow (Ex​per​i​ment 2) or both (Ex​per​i​ment 3). When first view​ing the blurry im​ages, par​tic​i​pants iden​ti​fied a few scenes. When view​ing blurry video clips, their per​for​mance im​proved with trans​la​tional flow, whether it was avail​able alone or in com​bi​na​tion with ro​ta​tional flow. Par​tic​i​pants were still able to per​ceive scenes from sta​tic blurry im​ages one week later. There​fore, trans​la​tional flow in​ter​acts with blurry im​age struc​‐ tures to yield ef​fec​tive and sta​ble scene per​cep​tion. These re​sults im​ply that ob​servers with blurry vi​sion may be able to iden​tify their sur​rounds when they lo​co​mote.
