On Learning to Recognize 3-D Objects from Examples
نویسنده
چکیده
Previous results on nonlearnability of visual concepts relied on the assumption that such concepts are represented as sets of pixels [l]. This correspondence uses an approach developed by Haussler [2] to show that under an alternative, feature-based representation, recognition is PAC learnable from a feasible number of examples in a distribution-free manner.

Spatiotemporal information during unsupervised learning enhances viewpoint invariant object recognition.
Recognizing objects is difficult because it requires both linking views of an object that can be different and distinguishing objects with similar appearance. Interestingly, people can learn to recognize objects across views in an unsupervised way, without feedback, just from the natural viewing statistics. However, there is intense debate regarding what information during unsupervised learning...
متن کاملExtending the Qualitative Trajectory Calculus Based on the Concept of Accessibility of Moving Objects in the Paths
Qualitative spatial representation and reasoning are among the important capabilities in intelligent geospatial information system development. Although a large contribution to the study of moving objects has been attributed to the quantitative use and analysis of data, such calculations are ineffective when there is little inaccurate data on position and geometry or when explicitly explaining ...
متن کاملHierarchical Multiclass Object Classification
Humans can use similarity between objects in order to recognize rare objects. They also make many abstract concepts when they see some objects very often. Interestingly, a large part of brain is associated with common classes like faces rather than rare objects like Ostrich. In our work we want to propose a model that has four mentioned characteristics. 1. Use more resources for categories that...
متن کاملLearning the 3-D structure of objects from 2-D views depends on shape, not format
Humans can learn to recognize new objects just from observing example views. However, it is unknown what structural information enables this learning. To address this question, we manipulated the amount of structural information given to subjects during unsupervised learning by varying the format of the trained views. We then tested how format affected participants' ability to discriminate simi...
متن کاملFuzzy Relational Model with 3-D Structural Information of Objects
An approarch is proposed that gets a fuzzy relational model of objects by taking 3-D geometrical information of objects obtained from stereo vision as inouts. To solve the scale problem occurred in quantitative representation of 3-D structural information of obiects and lower the ~ ~ ~--. matching cost, a fuzzy relational description language (FRDL) is defined in this paper that represents the ...
