视觉注意作为一种降低场景理解计算复杂度的智能机制,是目标检测、识别和定位等多种计算模型的基础。在本文中,第一次,生物约束模型的视觉注意力(具有对象识别和定位的能力)对大对象的变化,在虚拟现实中的视觉搜索任务的鲁棒性证明。该模型基于速率编码神经网络,并同时使用自下而上和自上而下的方法来识别和定位学习对象。此外,虚拟现实非常类似于真实世界的场景,其中类似人类的神经认知代理可以识别和定位15个不同的对象,而不管缩放,视角和方向。仿真结果表明,神经认知智能体在大约85.4%的场景中正确执行视觉搜索任务。
Visual attention, as a smart mechanism to reduce the computational complexity of scene understanding, is the basis of several computational models of object detection, recognition and localization. In this paper, for the first time, the robustness of a biologically-constrained model of visual attention (with the capability of object recognition and localization) against large object variations of a visual search task in virtual reality is demonstrated. The model is based on rate coded neural networks and uses both bottom-up and top-down approaches to recognize and localize learned objects concurrently. Furthermore, the virtual reality is very similar to real-world scenes in which a human-like neuro-cognitive agent can recognize and localize 15 different objects regardless of scaling, point of view and orientation. The simulation results show the neuro-cognitive agent performs the visual search task correctly in approximately 85.4 % of scenarios .
