Structural and view-specific representations for the categorization of three-dimensional objects
It has been debated whether object recognition depends on structural or view-specific representations. This issue is revisited here using a paradigm of priming, supervised category learning, and generalization to novel viewpoints. Results show that structural representations can be learned for three-dimensional (3D) objects lacking generalized-cone components (geons). Metric relations between o...
متن کاملLearning sparse representations of three-dimensional objects
Each object in our environment can cause considerably different patterns of excitation in our retinae depending on the observed viewpoint of the object. Despite this we are able to perceive that the changing signals are produced by the same object. It is a function of our brain to provide this constant recognition from such inconstant input signals by establishing an internal representation of ...
متن کاملGraph Representations of Three-dimensional Chiral Objects
Chirality of objects is a problem with important applications in biology, pharmacology, medical cosmetology, organic chemistry, inorganic chemistry, supramolecular chemistry, biochemistry, and other branches of science. In this paper we provide a solution for quantification problem of chirality for three-dimensional objects.
متن کاملMultimodal similarity and categorization of novel, three-dimensional objects.
Similarity has been proposed as a fundamental principle underlying mental object representations and capable of supporting cognitive-level tasks such as categorization. However, much of the research has considered connections between similarity and categorization for tasks performed using a single perceptual modality. Considering similarity and categorization within a multimodal context opens u...
