ANALYSES OF 3-D OBJECT RECOGNITION PROCESS BY PYSCHOPHYSHICAL EXPERIMENTS

心理物理学实验，揭示了在人类物体识别的观点依赖性和观点独立的属性，并指出，这些研究之间的根本差异，可以发现关于物质对象和实验范式使用。因此，有可能在这两种类型的实验中研究了不同的物体识别过程。为了评估这种可能性，我们进行了两个实验，分别研究了熟悉物体的命名和新物体的识别。结果表明，人类原型的物体描述包含丰富的组成结构信息，但与视图无关的属性只在有限的范围内被发现。因此，在这些原型被激活后，通过心理旋转的验证过程被认为是必要的，以检查对应观察到的意见。所提出的两个过程，原型激活和验证过程，可以调和矛盾， 关于我们 实验之间的时间点。研究表明，识别三维物体的反应时间与视点有关。我们已经考虑了依赖性反映了心理旋转过程的参与，该过程将观察到的视图转换为规范视图，并研究了三维物体心理旋转的可能途径。我们的实验结果表明，命名旋转的熟悉物体的反应时可以通过假设以下心理旋转的模型最好地预测基于以旋转为中心的坐标轴：首先（a）围绕矢状轴旋转，然后（B）围绕水平轴旋转，如果需要的话，然后（c）围绕垂直轴旋转。通过计算在描述物体所有可能视角的视球上出现最具遗传性视角的概率，定义了“遗传视角率”，发现遗传视角率可以很好地预测三维物体的优良度。最后，通过对婴儿物体识别过程的研究，发现低特殊频率成分在物体整体性沉淀中起着重要作用。少

Psychopysical experiments which revealed view-dependent and view-independent properties in human object recognition, and it is pointed out that fundamental differences can be found between these studies concerning the material objects and the experimental paradigms used. Therefore, there is a possibility that different process of object recognition have been investigated in these two types of experiments. In order to evaluate this possibility, two experiments which investigated naming of familiar objects and recognition of novel objects The results suggested that human prototypes of object have descriptions that contain rich information on component structure but view-independent properties ate found only in limited ranges. Therefore, after these prototypes are activated, a verification process by mental rotation is considered necessary to check correspondence to observed views. The proposed two process, the prototype activation and the verification processes, can reconcile contradicto … More ry points between the experiments. Which show view-dependence and view-independence.It has been pointed out that the reaction times for recognizing 3-D objects depend on view points. We have considered that the dependency reflects involvement of the mental rotation process which transforms an observed view into a canonical view and investigated possible pathways in which a 3-D objects are mentally rotated The results of our experiment s suggest that the reaction time for naming rotated familiar objects can be best predicted by the model which assumed the following mental rotations based on the observer-centered coordinate axes : first (a) rotation around the sagittal axis, and next (b) around the horizontal axis, then (c) around vertical axis, if necessary.Furthermore, we have analyzed the determinants for goodness rating on 3-D objects. 'Generic-view rate' was defined by calculating a probability of the most genetic view on a viewing sphere which describes all potential views of an object It was found that the goodness rating of 3-D objects can be well predicted by the genetic view rate.Finally, infants'' object recognition process was investigated and found that low-special frequency components take an very important role for object unity precipitin.
